Madonna with the blue diadem – Raphael

Several years ago I visited the prints and drawings room at the National Galleries of Scotland in Edinburgh and was treated to my own little exhibition starring a lovely Raphael drawing. While it’s nice to get close to such pictures, to take one’s time with them, to meet them as individuals, it is also extremely rewarding to get positively drunk on a rich and steady stream of Raphaels. An undeniable advantage of living in Vienna is that our galleries treat us to exhibitions that are far from modest; our ample imperial collections are embellished but hardly outshone by guest appearances from the Louvre and the National Gallery in London. Such frenzied visual gluttony leaves one with very different impressions of the overall trajectory of Raphael’s work than calm meditation on a single piece.

Allegorical figure of poetry – Raphael

For one thing, it struck me how important tone is to his compositional strategy. Right from the early preparatory stages (and from his early years), his torsos and legs are offset simply and elegantly by plain slabs of tone. The effect is remarkably spatial: tone really does work, it is by no means a filler. One watches him carve an arched back deep into the picture by means of crude but deliberately-placed tonal contrast. In more complex drawings with many figures, this same simple strategy becomes meaningfully elaborate. Tone relates each figure to every other, especially in terms of depth. Plain, round heads and simple arcs of arms are woven in and out, set back at different distances, and curled gently towards us by rolling rhythms established largely tonally. Gently undulating movements ripple through tranquil and otherwise crisp, idealised figures. The masterful, airy sense of space informs us that we are emerging from the stilted Dark Ages into the spacious, glistening pastures of the Renaissance; it invites us to suck in a deep breath of that heady air.

Raphael

The force of this tonal organisation carries over into his painting, which is luminous. The brightness of his figures still gleam against the bright jewel-blue landscapes. Rather than dull them to grey, Raphael neutralises them with white, keeping their contrast limited but their colour otherwise pure. Without invoking da Vinci’s atmospheric haze, Raphael offers us sharply-drawn cities that recede by fading to an icy blue; they retreat into the distance but glow as lavishly as the radiant figures.

It is a sheer delight to observe his methodical approach. Seemingly uninterested in the peculiarities of individuals, he treats them with egalitarian lines that harmonise their quirks into balanced lines and forms. Thus subdued, each ideal human becomes a conduit for graceful forces, and Raphael can make them dance, can animate these soft puppets with a living movement that courses through them with the steady and mesmerising will of flowing water. One observes again and again that he often draws whole scenes of nudes: thoroughly inappropriate nudes in solemn religious settings. Drawing is a tool of understanding, and Raphael acquaints himself with every aspect of his figures as he works variations of the picture.

Raphael

Alongside these careful nudes are painstaking drapery studies. A cloth hangs over a chair, as though it might be wrapped around a waist, and is reproduced faithful to life. Then it is redrawn, less stiff, with more emphasis given to the imagined meaty masses beneath. One sees immediately that he combines these two separate studies, these two firm foundations, into a meaningful amalgam of fabric and flesh–that each enhances the other, describes the other, that they move together. And his draperies are incomparably airy, infused with a lightness that only such sure knowledge of both figure and folds of cloth can achieve. The truly inspired pictures augment his understanding. Air blows up under garments and lifts them lightly, it teasingly curls their hems. The billowing, swelling folds extend the figures into otherworldly forms with a magical presence about them. What Raphael draws is too perfect to be real, and yet so natural as to seduce us into believing it anyway.

Raphael (print of a fresco)

Raphael’s drawing is perhaps most mesmerising for its delicacy. That simple chalk marks can produce such textural differences between skin and fabric is astounding. A supple arm or face can be as fine and smooth as porcelain, nestled into a rustling bed of hatching that describes those carefully-observed folds. There are some exquisite passages of hatching that run counter to the folds of the fabric, opening it out in a radiating fashion. Such control shows us where his attention lay, and while it might be far from the throbbing muscles of Michelangelo, or from the frenzied swirls of Leonardo, we appreciate that his own emphasis is equally compelling and equally distinct. Raphael delights us with a clarity that rings like crystal, with an enveloping vision of humanity that softens and perfects his figures into more noble and gracious manifestations thereof.

Raphael

Artists are often called upon to produce endless novelty, to demonstrate their ‘creativity’ by producing something entirely unexpected. Raphael’s tendency toward ideals or universals in his figures suggests a rather an urge to perfect each previous attempt, to take up the idea again and refine it. His inventiveness is the truly inquisitive kind that attends very carefully to its subject, seeking to extract the most pleasing and elegant and finally effortless solution that comes out of deep familiarity with that subject. This genuine inquisitiveness uncovers endless variety on a single theme, as is evident in his Marys. His parameters are tight–circular rhythms, pinks and blues, babies cradled in crescents of arms–but each new iteration probes the possibilities in a breathlessly fresh manner, the glowing and trembling air positively wet with dew.

Three graces – Raphael

The Albertina, swarming with visitors, gives one something else to reflect upon, which is the way people fear the art, and the way they talk about it. Whether a tour group or a pair of friends, two roles tend to emerge: one type stands helpless and intimidated before the Raphaels, the other speaks with authority. While one follows in silence, the other puts on her ‘tour voice,’ a dreadful monotone that indicates she doesn’t quite appreciate her listeners to be humans; or talks with adamant certainty about Raphael’s technical aims and his motivations as if they were solid facts. This last, particularly, strikes me: an appeal to the formal properties, but a very arrogant one that seems to impose more on the picture than it extracts from it. Or one overhears an appeal to formal properties that is infuriatingly empty: a teacher solemnly tells his students to come nearer to the drawings, and finally to ‘schauen Sie die Hände und die Füße an, wie die gezeichnet sind,’ (‘Look at the hands and feet, at how they are drawn,’) with no further comment, no indication of particularly successful or unsuccessful strategies, no disappointment that in these instances the hands are rather weakly drawn and clearly not the emphasis of these more compositionally-oriented drawings that incline rather more towards neglecting the details.

My humble artist companion and I enter the gallery with another attitude altogether. We come, admittedly, with our familiarity with certain Raphael paintings, of that single drawing (now on loan to the Albertina), filled with our predilection for Michelangelo, but with our eyes open, ready to greet the pictures as they are. Our conversation–sparse, because of our private absorption in the pictures–is quietly observational, relishing a confident mark, joying in vivid colours, delighting in the judicious variety of the mark-making, in an unexpected and strong row of square knuckles, but also regretting the careless sections, the limp passages that lack conviction. The longer we stay with the pictures and the more we think about his choices, we start to appreciate what makes Raphael distinctive, why Ingres would later strive after his elegant fastidiousness, how classical it feels, yet at the same time coloured with the jewel-like hues of the Middle Ages. We are always sharing, wondering, noticing. If these humble comments can give you some handle on Raphael, give you some way to think about the formal properties in a concrete way, open your eyes to the simple delight a picture can awaken in you, I sincerely hope they might bring you a step closer to genuine appreciation. For as Aristotle opens his Metaphysics: ‘By nature, all men long to know. An indication is their delight in the senses. For these, quite apart from their utility, are intrinsically delightful, and that through the eyes more than the others.’

The mirror (c) 2017 Samantha Groenestyn (oil on linen)

The connection between colour and geometry demands some attention. Richard Heinrich (2014: 41) argues that ‘there is always a tension between … colour space and the geometry of colour,’ that conceptualising colour in terms of space is not as simple as unearthing the underlying geometric principles that will take care of everything. He is, of course, correct in this. There are many rich and nuanced ways of conceiving of colour spatially, from Aristotle’s delightfully plain string of colours, which Newton (1672) eventually closed into a circle, which has been expanded both theoretically and experimentally into various three-dimensional schema that are as idealised or roughly-hewn as their methods dictate (Briggs, 2017). A geometric conception of colour space, like that of Philipp Otto Runge (1810), approaches colour from a purely theoretical side, permitting us the sharp analytical divisions of conceptual midpoints and the elegant polish of a sphere as the theoretical limit. The reality of colour, both for the physicist and the painter, is much rougher at the edges, much more irregular, much grittier. But this does not mean that some abstracted principles, deliberately divorced from the messy realities of light and pigment, cannot be united with the practice in an instructive way. Indeed, such conceptual clarity can help the practicing colourist organise her approach to colour, while still allowing the flexibility to adapt those principles to experience.

But this is not really the disjunction that Heinrich is getting at. Rather, he is concerned that a geometric model for colour tries to explain both our perceptual experience and our concept of colour, and that this uneasy compromise tends to destroy our concept of colour (Heinrich, 2014: 41-42). We establish a working web of relations, but relations between possibly infinite coordinates of hue-value-chroma, none of which bear any greater significance over any other such that they attract the familiar and seemingly meaningful titles of ‘red’ or ‘yellow.’ This is true, but it points to the greater underlying problem that our concept of colour is desperately flawed. That we conceive of colour so misguidedly despite our firmer scientific grasp on it has only negative implications for painters. Most pressingly, there is a pervasive and false belief that colour cannot really be taught, which lends it a certain mysticism both in philosophy and in art schools. This mysticism is only compounded by the fact that colour is persistently mistaught on the basis of our flawed conception of it. We need to reconfigure our concept of colour or, if that is too extreme, to at least separate out a working theory of colour that practitioners–painters–can rely on from a more experiential understanding of it. This, I think, is not so outlandish: physicists operate with a different set of primary colours without threatening our habitual perceptual ideas about colour. What needs to be teased out is the psychological conception of colour, dearly-held but quite unrelated to the models most useful to artists and physicists.

From Runge, 1810: Farbenkugel

The primary colours are a good place to start, especially given Heinrich’s justified criticism of Runge’s development of the colour sphere (Farbenkugel). Runge moves deftly from a triangle (picking out red, yellow and blue) to a star which incorporates orange, green and purple, smooths them into a familiar colour-wheel and fleshes the whole thing out into a ball. The dubious move (which Heinrich (2014: 38) does not let him get away with) is that he begins with certain geometric parameters but quietly dissolves them along the way. The triangle is made of points, marking out the primary colours, which are connected by lines, which signify the gradations between them. The triangle says that conceptually, we grasp the idea of a ‘pure’ red–it tends neither towards yellow nor blue, it is not in the least orange or purple, it holds a privileged status as a colour (hue) that every orangish red and purplish red does not. It says that while there are many oranges, there is only one pure red.

We can, however, conceive of a middle-orange, one that appears equally red and yellow, and a green that is no more yellow than it is blue, and likewise a perfectly balanced purple. Runge (1810) thus bisects each line and places each of these so-called secondary colours at the midpoints, forming a small inverted triangle. Perhaps what starts to go awry here is that the lines from green to orange, from orange to purple, from purple to green, do not really signify anything–just a gradation of muddy browns. Runge expands this second triangle without explanation, presenting us with two triangles which we could not, on geometric terms, distinguish, though they represent vastly different ideas: the hierarchy is dissolved. To gloss over this fact, Runge removes the points altogether, and it is this that Heinrich (2014: 40) particularly objects to. The model abandons its initial claims about the significance of some colours above others and drops into a fluid mass of relations.

Runge’s Farbenkugel development

Runge’s move is questionable, but the result is perhaps not so catastrophic. This is not only because in practice, one can navigate colour more nimbly and efficiently when one thinks only in terms of relations rather than absolutes (for example, recognising that this mix should be bluer than that mix, rather than trying to match a particular fixed shade on a colour chip). But also because our attachment to the primary colours might be unjustified. Runge’s initial choice of red, yellow and blue–even as conceptual ideals–could be as arbitrary as his model ultimately suggests.

As David Briggs (2017) describes, the concept of a primary colour is itself somewhat muddy. We generally bring to it the idea of an ‘unmixed,’ ‘pure,’ or ‘primitive’ colour. But these intuitions bring various assumptions, mostly derived from paint, which are simply nonsensical when we describe colour in terms of light. In light, common colours compound the reflectance: green does not ‘defile’ red, but their shared components yield yellow and their differing components cleanly cancel out. Another enduring sense of ‘primary colour’ is a colour from which all others can be derived. This would already force us to branch colour into two separate realms, one of paint and one of light, which revolve around different base colours: subtractive and additive primaries, respectively. Briggs (2017) assiduously notes that this formulation brings conceptual dangers of its own, particularly that ‘it is a small and slippery step from the observation that all hues can be made from three primary colours, to the assumption that all hues are made of those three colours,’ which would be another paint-oriented bias.

To further complicate the idea of a primary colour, Briggs (2017) rightly points out that in fact we cannot derive all colours from just three. For the painter, purple is notoriously elusive because red pigment is still too yellow, thus the mixture of red and blue tends to result in an unsavoury brown. Painters resort to other pigments such as a rose (suspiciously magenta-like) or to outright purple pigments. Perhaps even more shatteringly, the additive primaries are no more certain, they do not correspond to any specific red or green or blue wavelengths; rather, Briggs describes them as optimal ranges of wavelengths. Defining primary colours at all turns out to be a hazardous and imprecise enterprise; at the very least this should cause us to question what reason we have to insist on points in our geometric model of colour.

Copy after Mestrovic

That reason might have something to do with our perception. Ewald Hering (1878) describes another set of primaries: the four psychological primary colours of red, yellow, green and blue. These four colours are privileged for having a ‘mentally unmixed’ status, while all other colours seem, to our minds, to be gradations between adjacent colours. This is why an orange can satisfactorily be described as a yellowish red, but we feel uncomfortable to describe a green as a yellowish blue. This seems to be the unrelinquishable ‘grammar of colour’ that Heinrich (2014: 41) particularly wants to hold onto: the sense, based in our experience of colour, that these colours are distinct and in this way primitive. This stance seems as arbitrary and as defensible as any: green is rigid and present in our experience in a way that orange is not. Or as Heinrich (2014: 41) puts it, ‘we will have to admit that green lies between blue and yellow in a fundamentally different sense as orange between yellow and red.’ But for the painter, green remains a mixture of yellow and blue, just as red may be a mixture of rose and yellow, depending on her pigments. And for the physicist, green is the absence of blue and red, while orange is a more complex array of light. Our mental divisions–what we project onto the world and how we break it down–do not correspond to the ‘input into our visual system’ and the stimulation of our rods and cones (Briggs, 2017); nor do they correspond to the pigments that happen to be available to painters. And that might be just fine.

What I propose is to keep these three types of colour systems distinct, while acknowledging their intersections. Runge’s colour sphere perfectly captures the fluid conceptual relations between hues and their values and chroma for the painter. Since it is advantageous to think relationally rather than in absolutes when trying to establish a harmonious colour context in a painting, an idealised, geometric model of three-dimensional colour space proves a useful tool for the painter. Such a tool, being relatively simple, yet rich and adaptable to any situation, empowers the painter both to organise her observations and translate them into paint, and to teach a coherent and systematic approach to colour to her students.

Physicists, meanwhile, may continue to measure wavelengths, discuss energy, and optimise their additive primaries of red, green and blue. Since the physicist is concerned with describing what light information enters the eye, his measurements do not undermine or contradict the relational model of the painter’s pigments. Rather, the two conceptions intersect unexpectedly beautifully: the complementaries of the additive primaries (red, green and blue) are cyan, magenta and yellow. These last three are used in printing to achieve the maximum range of mixed colours, and can be shown to yield a broader gamut of colours in paint than red, yellow and blue. This elegant inversion, identified by Helmholtz (1852a), perhaps gives us a firmer reason to fix cyan, magenta and yellow as the optimal subtractive primaries, if indeed we would rather retain points in our geometric model of colour space. At the very least, we might revise our pedagogical practices and stop teaching painters colour theory based on the psychological primaries rather than on the actual properties of light and pigments.

A painter does not need to understand the physics of light in order to manipulate paint. The systems remain conceptually distinct. But I think it would be correct to say that not only is the painter’s system inversely related to the physicist’s; it is also subordinate to it in the sense that after the pigments are applied, a painting, too, is simply an object reflecting wavelengths of various frequencies into the rods and cones in our eyes. In this sense, as Briggs (2017) argues, the painter works with light. He offers a particularly nice example that bridges the two systems in the practice of painting. A painter can drag paint roughly over dry paint of another colour such that the colour underneath sparkles through the gaps, or lay small strokes of different colours next to each other as the Impressionists did. The eye mixes these physically unmixed colours in an additive manner. Scientifically, it would be called ‘additive averaging mixing;’ painters call it ‘optical mixing’ and use it knowledgeably to great effect. Briggs (2017) further argues that the painter works with perception, and that what the spectator perceives remains largely geared around the four psychological colours, by which he makes sense of the painting.

And so we return to the ‘concept of colour’ that Heinrich is reluctant to dissolve into the more sophisticated systems. Drawing on Ludwig Wittgenstein, he relates it to a ‘grammar of colour,’ which modestly and openly captures something but not all of our experience of colour (Heinrich, 2014: 41). This is the key: none of the systems of colour we have discussed capture everything of our experience of colour; each operates in its realm without excluding or invalidating the others. An artist might comfortably talk of a ‘blueish yellow’: her vivid cadmium yellow paint is redder than the mental ideal of yellow; she can physically add blue to it to make it more yellow. But for the spectator, who now sees an ideal yellow in the painting, no feat of mental dexterity seems to allow him to imagine a blueish yellow. The slightest introduction of blue slides the colour irrevocably into the lush spectrum of greens. That is simply the mental category of green. And since, mentally, green is opposed to red, our brains cannot grasp a red that leans towards green, or a green that leans towards red. The curious thing is that yellow and blue, though they complement as strikingly as red and green, merge effortlessly into a pleasing colour. This says very little about how light or pigments operate, but it says a great deal about what we project onto what we see. Perhaps a phenomenology of colour would treat of questions like these.

Copy after Mihanovic

In any case, as spectators with firm mental categories for colour, the are things we can say about colour, and things that we cannot. Wittgenstein (LWL, 8) is not so facetious to suggest that certain models of colour–such as his favoured colour octahedron–are ‘really a part of grammar… It tells us what we can do: we can speak of a greenish blue but not of a greenish red etc. … Grammar is not entirely a matter of arbitrary choice.’ Grammar has its role, and need not be threatened by geometrical schema designed to help the painter navigate colour space, any more than it should be threatened by physics. A grammar of colour seems to attempt to describe our intuitions about colour based on how we perceive it, just as the grammar of a natural language attempts to explain how we structure our expressions, even though it may consist more in explaining exceptions than syntactic regularities (Chomsky, 1965: 5). Perhaps the intersection between a geometric colour space and a grammar grounded in a phenomenology of colour would reveal yet more rewarding insights, perhaps as beautifully connected as light and paint have proved to be.

Just trying to say it right

The struggle (c) Samantha Groenestyn (oil on linen)

There are few people who can both write about art and produce it. I have been cautioned against attempting the superhuman feat of doing both. Undoubtedly, there is a lot of impassioned but mutilated thought that has been scribbled down, and a lot of cleverly strung together ruminations that entirely miss the point of the artwork in question. Regrettably, frenzied vehemence and smooth yet detached theorising tend to be accepted as legitimate encounters between art and writing, as though art ought to infect words with its garbled passions, and as though crystalline categorisations really said the whole of what is to be said about art. An honest, steady, thoughtful middle ground is difficult to attain, but it is this gravity and lucidity that Susan Sontag manages to achieve in her essays on film, theatre and literature. Against Interpretation and Other Essays thrusts us deep into the works in question, considering them, as it were, from the inside. Sontag is both artist and thinker: author and critic; able to love and to measure, to experience and to judge.

The essay. Perhaps, itself, a dying artform. It is easy to dash off an article, a commentary, a review, some quick thoughts, or a summary. But to engage with ideas–whether they emerge from books or paintings or elsewhere–involves something more. It involves a cohesive train of thought, an argument, an insight, a real willingness to enter a zone of intellectual conflict. In the case of writing about art, the essay is a knife, sharpened for the express purpose of permeating the flesh of the artwork to get at what is inside, to taste it, to judge it, to display its qualities for what they are. Perhaps things were ever as dire as they seem to be now: but writing about art, if at all penetrable, is so often vapid promotional cotton candy; sugary teasers that are little more than loosely-clad advertising, slick and professional, treading lightly so as not to crush any toes.

As for myself: Perhaps you have traced my artistic education, observing my first tentative steps into the world of painting, as I respectfully recounted it online. I kept my eyes open, I exposed myself to many things. I thought fiercely and critically about all of it–all of it–I agonised over the disappointments, the ineptitude, the obtuseness, the deception, the sheer ignorance. I think one does not improve unless one learns to discover faults, and can explain why they are faults, and propose ways of addressing them. As an artist, I kept these considerations to myself and applied them in practice. But in writing about art, I maintained a certain reverence. I made a conscious choice to be just, but positive: to focus on the best things.

Copy after Klinger

A curious but probably predictable thing came from this: I was plagiarised. My thoughts found themselves rehashed, sloppily restitched and dimly cited in monstrous word-spaghetti that no longer conveyed the original idea, if any at all. I went to exhibitions where my own words were read back to me, translated into German. It made me consider who has these jobs, and why they don’t know what to say about art. Certainly, artists don’t always know how to write about their work, and that’s why they paint it. But if people who are otherwise proficient writers can’t produce a faithful and insightful piece on a work of art, the problem seems to be deeper. They cannot think about art. They stand before a painting in a distracted panic.

But not all of us do. Some of us approach an artwork attentively, quietly, patiently. We take our time with it, revisit it, think on it. Sontag (1966: 12) is not at all incorrect to say that ‘attention to form in art’ is urgently needed. The formal properties–how colour is used, how strokes are applied, linear rhythms and the balance of shapes–might not be the entirety of a painting, but taking them in is surely the place to start. The little ripples of paint will soon chase away the anxiety, drawing us into a silent and timeless realm, inviting us to reflect. Our thoughts will scurry around with the worries and agitations that we hug to ourselves every waking minute, but these, too, will slow down. A painting is a shy creature, but approached through its form, it might let us near it.

Copy after Claudel

Sontag’s essays, as a collection, make me consider the art I encounter and what is being said about it. I have known highly trained painters, self-taught painters, casual painters, designers, illustrators and conceptual artists across the world. Sontag looked fiercely at the world around her, she wrote about the time in which she lived, about America, about Europe. Her essays are not lighthearted, not necessarily short, not lazy Sunday supplements. They are the product of an active and alert mind wrestling with works that stimulate it or disappoint it and unleash a response. Goodwill is no vice, but the critic, the thinker, has work to do, and goodwill must not cloud the public discussion about art. We came to be impressed, to be stirred, to greet grand ideas–when art fails us, it is not we who should be ashamed, apologetically carrying home our embarrassment at the artist’s deficiency like a tail between our legs. Our critical faculties have not failed us. The art is rubbish.

Sontag (1966: 12) demands a kind of criticism that genuinely responds to art, rather than one that ‘usurp[s] its place.’ Words continue to threaten to replace the artwork, but the situation has grown considerably worse: the words are disposable, interchangeable, unilluminating and cheap. Barely able to capture a coherent thought, they could hardly hope to upstage an artwork. The real threat is whether such vacuous feel-good writing blinds us to art entirely, dulling our sensibilities, subduing our objections. The remedy has been around for some fifty years. We need:

‘Acts of criticism which would supply a really accurate, sharp, loving description of the appearance of a work of art. This seems even harder to do than formal analysis.’

(Sontag, 1966: 13)

The conjunction of sharp and loving is surprising but utterly natural. For how can one love a painting without discernment? How can one withhold affection from a painting that satisfies visually and stirs thoughts even in the silent mechanisms of its construction? Sontag (1966: 14) urges us to recover our senses, and that call is no less urgent now. Once we’ve learned to trust our senses, we must also remember to sharpen our judgements of what we perceive: to be fair, incisive and to demonstrate our love for thoughtful, well-crafted art.

A full spectrum

Dutch self portrait (c) Samantha Groenestyn (oil on linen)

Early Rembrandt: his colours are bold and gleaming, his compositions elaborate and ambitious; the drawing is wobbly in places. But Rembrandt is unmistakably there right from the beginning. His early Historical Scene reminds me of the clumsy vigour of the youthful Velazquez who, in just a few short years, elevated his painting dramatically, adhering to his same vision but finding more and more assured means of expression. Delacroix (2010: 141) exclaims of Rubens: ‘It is very evident that Rubens was no imitator; he was always Rubens.’ One feels seized by the same conviction when one stands before an early Rembrandt, and this is reassuring. Finish and fluency come with time; originality of conviction and sensibility shine through in spite of underdeveloped abilities.

Detail of Rembrandt, Historical scene

The Rembrandthuis is a veritable cavern of treasures, augmented by the practical demonstrations of printing etchings and mixing up paints from pigments. Huddled in Rembrandt’s tight and dim etching studio, privy to etching, drypoint and engraving techniques, peering into pots of ink made of burnt rabbit bones and linseed oil, watching the hasty print come out clouded with too much ink on the clear surface, one emerges with an entirely different understanding of what Rembrandt produced. Encountering prints made by his own hand, and able to compare them with the efforts of others to recreate them from the same plates, or to make copies of them, one is struck by the artistry of the entire process and of the masterful hand and inventive mind behind them.

Rembrandt’s atmospheric prints make use of a full spectrum of techniques, he pushes every method for what it can give him, overlapping and merging and setting them off against each other to maximum effect. Drypoint curves with their fuzzed burrs render hazy leaves blowing in the trees, but crisp, sharp, engraved lines lightly caress figures in blazing light in the foreground. The darks are an absorbing mixture of furious hatching and the controlled rubbing of ink; they transition thickly into light passages, and one appreciates that this transition is supplied deliberately and carefully, it does not take care of itself or lazily blend two unrelated areas.

Rembrandt

That thick hatching is never harried or negligent; it alters course because the image takes it there. Rembrandt is unafraid to search around the surface of the object as if actually feeling his way around it, little clumps of hatches rolling this way and then that way, breaking into each other like rippling waves in a canal. His inventiveness with mark-making is astonishing, lively and ever responsive to the subject.

Rembrandt, Militia Company of District II Under the Command of Captain Frans Banninck Cocq, known as the Night Watch, 1642

Returning to the Rijksmuseum to see his paintings, after emerging from the intricate world of his etchings, his compositional prowess is instantly striking. It migrates directly from his small and tightly-spun etchings to the grand format, bringing its seething dark patches and soulful transitions into the light and its expert contrasts that make the light flash where it really needs to. We are all painting with the same ground up bits of dirt in linseed oil. But Rembrandt knows how to find an impressive range within the mix, how to play tones and textures off against one another for specific effects of light, how to use lightness of touch to convey brilliance, how to deepen space with quickly engulfing shadows. The Night Watch dazzles less for its individual perfections but rather for its pictorial unity. The pictures that flank it, decked with smooth drawing and inventive rendering, ring with even-handed clarity. Each face in them is well-depicted, each pose carefully arranged and interlocking with the next, each figure grouped with others, yet shown in its individuality. Yet in these pictures, composition is conceived much more as a linear arrangement of given subjects. Rembrandt sacrifices much–he gives us stumpy legs and obscured faces–but he has puzzled over how to present us with a picture, not simply a spread of information. The vast stretch of darkness across the top reads just like his etchings–a thick darkness hangs heavily over the militia, certainly unnecessary for the reproduction of their likenesses, but indispensable for a resonant, night-swamped image.

Delacroix (2010: 209) laments that ‘The majority of painters who are so scrupulous in their use of the model spend most of their time putting faithful copies into dull and ill-digested compositions. They believe that they have accomplished everything when they reproduce heads, hands and accessories in slavish imitation of nature without any relationship with one another.’ One is left in no doubt that Rembrandt digests his compositions–that his smaller works, many of them hardly more than thumbnails, give him such a sense for the whole, allow him to extract salient passages and subdue others, or weave them more subtly together, in a way that eludes more faithful painters. His compositions do feel chewed–it feels as though he is intimately acquainted with them, as though he has explored every crevice of them and considered their weight and role with respect to the whole. And seeing etchings in their first, second, sixth, seventh states, seeing the gentle alterations, and the sometimes dramatic revisions, one sees that Rembrandt considered and reconsidered, reworked his images, knew them thoroughly and beat them into the shape he wanted. This is a kind of familiarity and deliberateness that one does not meet with often.

The effect

The drawing class (c) 2017 Samantha Groenestyn

Images seep into language, and in so doing they add colour and liveliness. The metaphor chases after the potency of the image, abandoning the bald precision of description for a surprising visual equivalence painted in words. But Lichtenstein (1993: 204) is eager to persuade us that the image itself is something autonomous and specific. Though it can be imported into language, it does not consist in language. Nor is it simply the flipside of verbal description, an illustration of words. Our encounter with the image should reach beyond the boundaries of language.

Lichtenstein’s (1993 [1989]: 4, 63) incredible book, The Eloquence of Colour, champions the unruly and indispensable element of painting that is colour, the rogue party in painting’s troubled relationship with philosophy. She sees in colour–stubbornly material, emotional and seductive–the very thing that makes painting both distinct and effective. It is the part that Plato could not subdue, when he rightly recognised the seductive and deceptive threat of the image. Plato’s move, Lichtenstein (1993: 142) explains, was swift and decisive: he derailed the theoretical hopes of the image by framing the debate on the territory of language. The image must defend itself by the standards of discourse, and so too must painting if it wishes to emerge from the mechanical arts and prove itself a ‘legitimate form of knowledge’ (Lichtenstein, 1993: 204).

Even Aristotle’s defence of the visual does not challenge this founding assumption, which has plagued the visual and performative arts ever since (Lichtenstein, 1993: 62). He resigns himself to the ontologically deficient status of materiality, to the inferiority of appearances and the Spectacle (Aristotle. Rhet. III.1, 1404a1-4, trans. Roberts; Poet. B.6, 1450b17-19, trans. Bywater; Lichtenstein, 1993: 63). Colour suffers from this prejudice more than drawing–for drawing is crisp and measurable, and able to describe a story, and thus more readily tamed for discursive purposes. Yet in defining the image as something linear and illustrative–as the metaphor–philosophical discourse frames the question for its own advantage, constructing a straw man which it then proceeds to dominate (Lichtenstein, 1993: 44; 82). Painting, resplendent with colour, defies discourse because it does not consist entirely in drawing. The image ought to defend itself precisely on its own non-discursive grounds.

This discursive attack that puts the image on the defensive is precisely the fate suffered by rhetoric, and Lichtenstein thus finds in rhetoric an unexpected ally for painting (Lichtenstein, 1993: 205). Discourse seeks to distance itself from rhetoric, demanding logical rigour in arguments above persuasive delivery of them. The visible, theatrical aspects of speech open the door to all manner of deception. The charge of sophistry is levelled at both rhetoric and painting, Lichtenstein (1993: 68) argues, not simply because they are visual, but because of how persuasive the visual is. Their very charm, their incontestable effectiveness, is exactly what sparks this mistrust.

Discourse may colour itself with metaphors, but rhetoric strides to the edge of logical argument, sets its words aside and simply shows us. We hear the image in discourse; we simply see it in rhetoric (Lichtenstein, 1993: 129). Action is no metaphor. A forceful gesture is forceful; a proud bearing is proud; a wavering voice does waver; a heavy silence bears down on us heavily. ‘Persuasion is clearly a sort of demonstration,’ says Aristotle (Rhet. I.1, 1355a4-5). These actual, active demonstrations threaten language–they suggest a deficiency in language, and they hint at their own independence from language, their escape from the carefully defined terms of language (Lichtenstein, 1993: 92, 111). The hierarchy of language above the image might be overturned, the image might prove stronger.

But neither Lichtenstein nor Aristotle attempt to invert the traditional hierarchy. Lichtenstein (1993: 75, 111) would rather abandon hierarchies altogether, and clarify instead how the visible and the discursive complement one another. Aristotle (Rhet. I.1, 1355a20-25, 1356a20-25) still requires that the orator ‘be able to reason logically,’ and thus considers rhetoric ‘an offshoot of dialectic’ rather than a rival; the orator cannot afford to let truth itself go unnoticed merely because his audience pays too little heed to his intricate arguments. Platonism urges us to look for hierarchies and homogeneity in theories of representation, Lichtenstein (1993: 55) suggests; Aristotelianism tends to permit more heterogeneous theories of representation, the kinds that embrace logically elusive concepts like desire and pleasure.

The sign itself represents the attempt to ‘master the image logically’ (Lichtenstein, 1993: 51). The sign models representation on language: it assumes that representation, too, must be discursive. It implies that every visual, like a word, stands in for what it represents, and that this is how it acquires meaning. There is a referential relationship between the sign and what it signifies (Lichtenstein, 1993: 179). Lichtenstein counters that meaning exists in the image as a unity, it permeates its materiality; even without precise contours a painting can persuade us through a haze of convincing colours–the part that Descartes (2008 [1641]: 15) says remains true when all else is fictitious. Wherever we try to interpret, we seek a referent for a sign; whenever we speak of resemblance, we are making a comparison between two disconnected things, we are approaching the painting with a discursive attitude (Lichtenstein, 1993: 51). Representation is much simpler if we take rhetoric as our model: the painting, like the orator, simply re-presents the very object or emotion before our eyes (Lichtenstein, 1993: 123). It does not tell, it shows.

The most pressing thing, then, is not how much a painting resembles its referent, how accurately it embodies this information, but rather how captivating it is. The painting must, like the orator, hold our attention, capture our fancy, and move us. Lichtenstein (1993: 180) argues that ‘truth in painting lies in the effect of the representation on those who see it’–that representation consists in perception, which takes place in the viewer, not reference, a relation between the painting and its referent.

Insisting on the effect rather than the internal cohesiveness of the painting itself, and on what the artist intended to embed in it, seems problematic at first glance. But this emphasis on perception has less to do with private, subjective interpretations of a painting by scattered viewers, and more to do with an immediate sensory encounter with it. For interpretations, you will recall, are discursive decodings of images. In placing perception at the centre of our theory of representation, we are exchanging the cerebral encounter with the painting for a sensory one: we are approaching it on material grounds, responding to its material presence with our bodily awareness. We let our eyes apprehend the painting, we let them roam where it urges them, we let its mood wash over us, we trust its silent proddings rather than searching for intellectual substitutions we might make.

Unlike the discordant diversity of subjective interpretations, I would argue that this immediate sensory apprehension brings us much nearer to the intention of the artist. It is the way a painting seems to ‘come across directly onto the nervous system,’ as Bacon (1975: 18) strives after; it reflects Wollheim’s (1987: 43) observation that the artist assumes the dual role of artist and spectator in one, constantly testing and retesting the painting’s effect on herself, in order to know whether it will have the same effect on other spectators. ‘The painter’s pleasure is also that of the viewer’ (Lichtenstein, 1993: 182). The spectator comes nearer the painter’s intention if he simply perceives the painting and lets its silent visual elements work on him.

Yet even the path of perception is fraught with philosophical difficulties. Descartes has long since challenged the ontological status of sensory perceptions, finding a way to convert them into intellectual ideas independent of the body. For if we experience sensations in our dreams, they must, reasons Descartes (2008 [1641]: 14; 20-1), have very little to do with physical experience. Scoring points on the side of discourse, he (2008 [1641]: 23) concludes that ‘perception … is an inspection by the mind alone.’ Kant (2009 [1783]: §1; §10) is clear to point out that we are dealing with metaphysics, not physics; whatever a physical thing is, he argues, all we can measure is our own idea of it. Materiality has suffered heavily under our discursive tradition of metaphysics. Arguing for the significance of the material and our perception of it is no small task within this enduring theoretical domain.

Perhaps the best route out is that suggested by Lichtenstein (1993: 182): to prove that illusion is no deception, for the simple reason that it shows itself. The illusion never asks us to believe in its truth, it never attempts to stand in for reality. It shows us something of the world, all the while admitting its own artifice, and we indulge ourselves momentarily in the illusion because it is pleasurable (Lichtenstein, 1993: 179). Painting is comparable to cosmetics: it seeks to delight us, to captivate us, to seduce us, but not to trick us into believing in a false reality. This playful artifice does not deserve the accusation of sophistry, argues Lichtenstein (1993: 187); rather, the kind of persuasion that promises truth by airtight feats of logic but quietly leads us astray is sophistry. ‘What makes a man a ‘sophist’ is not his faculty, but his moral purpose,’ retorts Aristotle (Rhet. I.1, 1355b15-20). The key, Lichtenstein (1993: 181) insists, lies in realising that truth in painting, like in rhetoric, is measured by its effectiveness in the spectator, not by its relation to reality or our idea of it.

To establish painting’s theoretical validity, then, on the grounds of its rhetorical persuasiveness rather than on discursive grounds, we need to show how this effectiveness can be deliberately achieved. Generally, a discipline has had to prove itself on both theoretical and pedagogical grounds to be recognised as a liberal art: Lichtenstein (1993: 139) describes the rocky emergence of the Royal French Academy in 1635 and painting’s troubles in both domains, particularly the reluctance of the newfound professors to verbalise their practice. Lichtenstein (1993: 152) surmises that ‘drawing is the only thing in painting that can really be subjected to rules’–and thus the only part of painting which can truly be taught, and systematically theorised about. Here we will raise a resounding objection: colour can indeed be taught, and thus we can put forward an alternate way of theorising about painting, one that suits colour and drawing equally, and that accommodates a perceptual theory of representation.

First we need to be clear what we mean by ‘rules.’ I am not endorsing binding, homogeneous laws of painting. Rather, I am arguing for systematic, orderly but adaptive principles that approximate our perception and work in conjunction with it. They explicitly avoid the strict recipes and dogmas of the studio; they permit great but knowledgeable flexibility in technique. They require each artist to develop her own sensibility, to order her perceptions according to her own aesthetic preferences–they demand great facility and understanding but also offer the greatest liberation from rules and haphazard fortuitousness alike. They are not rules at all.

They are the kinds of systems described by Panofsky (1991 [1927]: 28-30) in his book on perspective, which emphasises the difference between the rigid mathematical space that our linear perspective imposes upon space as we actually perceive it through two spherical eyes, but which we adapt to our aesthetic purposes nonetheless, and the kind of systems described by Runge (1810) and more lately by David Briggs (2017) which describe colour space three dimensionally, either strictly geometrically like Runge, or in conjunction with light indices like Briggs. These systems deny absolutes; they acknowledge that what we perceive is difficult to describe, but they find relational ways to do so that encourage the active participation of the artist.

And, being able to be taught, these systems meet both the theoretical and the pedagogical requirements of a liberal art (Lichtenstein, 1993: 151). They achieve all this far from the narrow demands of language and discourse, holding fast to a rhetorical conception of representation, embracing what is explicitly visual in painting, preserving and promoting its characteristic and autonomous effectiveness.

Geometry & painting

Adèle (c) Samantha Groenestyn (oil on linen)

Importing mathematics into painting has some potentially grand implications. The idea makes me flush with uncontainable excitement; it smacks of Descartes (2006 [1637]: 9) and his methodical approach to knowledge, and I would echo his rationalist sentiment: ‘I was most keen on mathematics, because of its certainty and the incontrovertibility of its proofs.’ This unlikely marriage between mathematics and painting is especially dear to me because it offers something steady and dependable in terms of colour and not merely in terms of drawing; it promises to embrace the entirety of painting with its sober orderliness. This systematisation hardly destroys the poetry of painting. Rather, it allows us to sharpen our technical methods, which equips the genius (of the Kantian flavour) to paint something deeply insightful and moving. And it promises a double elegance: the sight of the painting itself, just like the sounds in music, may please us, and at the same time be grounded in delightfully crisp mathematical relationships, just like the improbable mathematical elegance of harmony in music.

These longings for order and systematisation sound rather like seventeenth-century aspirations to elevate painting to a science, or at least to a liberal art, which has much to do with shedding its humble craft status, as a trade practiced by illiterates. Painting has certainly made many efforts in this direction; it may boast of its academic status now that it is so commonly taught in universities rather than in ateliers, now that it defends itself verbally and indeed often consists more in its verbal conception and explanation than in its visual execution. But perhaps these victories are no victories at all: they strip painting of the very things that distinguish it as painting. Painting might have done better to have sought an intellectual ally in mathematics rather than in language, for there it would have found ways to describe its visual concepts succinctly and precisely.

This camaraderie is most apparent when it comes to colour. Colour is the rogue that has been seized by painters who want to defy philosophical discourse, and it is the uncontainable element that philosophy has used to subordinate painting. It seems to defy principles, thus it eludes philosophers, and it seems to operate largely by inspiration, superstition and magic, which seems to be attractive to painters. Across both disciplines, there is general agreement that colour is definitively not rule-amenable, while drawing is. Jacqueline Lichtenstein (1993 [1989]: 4; 62-3), in The Eloquence of Colour, traces this long-standing tension back to Plato and Aristotle, observing that ‘being material, colour has always been seen as belonging to the ontologically deficient categories of the ephemeral and the random.’ Philosophy has, she writes, thus favoured the more conceptually manageable element of painting: drawing (Lichtenstein, 1989 [1993]: 4).

If colour does not lend itself to principles, this has another, more practical, result. Philosophy aside, it means that colour cannot be taught. This lends itself to all varieties of unwelcome mysticism, that I personally would like to see chased out of the discipline of painting. It suggests that painters are ‘gifted,’ that they are conduits for ‘inspiration,’ or that they must operate by chance–all of which deny that painting is a disciplined skill that can be developed and improved and harnessed for aesthetic purposes. This is an unhappy state for painting to be in, for it grants artists license to all sorts of nonsense and self-indulgence, and abuses the viewer with all manner of ineptly executed work. In short, it encourages carelessness and invites decadence. Painting is visibly decaying before our eyes.

In the face of these two apparent deficiencies, I want to argue that the emphasis on drawing–both as philosophically acceptable and as practically teachable–is misplaced. Drawing certainly does lend itself to principles which can indeed be taught, and perhaps this fact is even overplayed. There are elements to drawing that cannot be taught, because each draughtswoman will adapt the learned principles to her own sensibility; she will interpret them, introducing a quality of line that no one else has. And, more broadly, the principles that are discussed and taught are not incontestable facts of existence. This is very clearly described by Panofsky’s (1991 [1927]: 37) contrast of spherical and linear perspective. Lastly, I want to raise a surprisingly little-grasped fact, one that is also popularly rejected by painters: colour is indeed amenable to principles, and there are painters who work with these principles and succeed in teaching them. Colour is very acutely described by geometry. In our infatuation with language, this straightforward ordering of colour has persisted largely unnoticed for at least two hundred years.

Lichtenstein (1993 [1989]: 142) notes that ‘ever since society has set a hierarchy among human activities, their relation to language has been the ultimate criterion for the establishment of a division, both social and philosophical, between the noble arts and the servile trades.’ Because of this, she explains, painting has sought to prove itself by ‘literary credentials;’ in order to do this, it has been expected to ‘satisfy both theoretical and pedagogical objectives,’ as we have already considered (Lichtenstein 1993 [1989]: 142; 151). Since she accepts that colour defies principles, she looks to rhetoric to redeem the intellectual status of painting, a fascinating move that demands more attention elsewhere, but we may here respond with our geometry of colour.

Copy after Rodin, Burgher of Calais

A fascinating little tract by Philipp Otto Runge appeared in the early 1800s. His Farbenkugel, or ‘colour sphere,’ is a mathematically pure way of conceptualising colour. It conceives of the relations between all colours three-dimensionally. He begins with a flat triangle that represents the three unmixed colours of red, yellow and blue. Each line is bisected to indicate that, mathematically, the secondary colours are the halfway points between each of these: orange, green and purple. These six points are extended out to the edges of a circle, which is then pierced by a perpendicular axis at whose poles stand white and black. The mid-point of this pole is, mathematically, a mid-tone grey. As colours move directly across the horizontal axis, they are neutralised by their mathematical opposite, entirely cancelling each other out as grey at the mid-point–yellow becomes, not more purplish, but more grey, as it moves towards purple, its opposite. Green and red exist in the same relation, and orange and blue. The knowledge of these relationships means a painter in fact need not use a black paint to recreate these relationships in paint: grey is not the absence of colour, but the annihilation of one colour in its mathematical opposite–‘alle einander auf derselben Gerade gegenüberliegenden Farben [sind] als Kräfte anzunehmen, welche einander entgegenstehen und sich durch ihre Vermischung zerstören in Grau’ (‘all colours that lay across from each other on the same line are to be assumed opposing forces that, upon mixing, annihilate each other in grey’) (Runge, 1810: 28). The rest of the sphere is filled out by every conceivable mixed colour and in every level of lightness and darkness, vividness and neutrality. The whole thing is most easily grasped visually, and this is the advantage of geometry.

(After Philipp Otto Runge)

It is a very beautiful model, one developed concomitantly with discussions with Goethe, and a living idea still used and taught by artists who appreciate the more rugged borders of three-dimensional colour-space. But more than this, the emphasis on relationships allows a shift in thinking: rather than considering colours as absolutes, bound to precise recipes of two-parts cadmium yellow to one-part prussian blue, they may instead be managed and manipulated as a complex but entirely rational web of relationships. This means, in fact, an emancipation from the types of dogmas that more mystically-inclined painters tend to bark at other painters: it means a shift from objectively defining colours to subjectively experiencing them. It allows a painter to recreate her perceptual experience of seeing colours; it allows for the fact that a certain mixture can appear pink or green, depending on the context it is set in. It marks a dramatic difference between painters who ask ‘what colour this really is,’ and those who ask how they perceive it. The second mindset affords far greater flexibility and dexterity with colour. And it can be taught.

(From Philipp Otto Runge, Farbenkugel)

This kind of dexterity is important because ultimately, while we might define our concept of colour in a pure mathematical way, paint itself does not respond to such precise geometrical divisions, and does not correspond so precisely to light. The painter must cope with two additional overlays to her mathematical concept of colour: the chemistry of paint and how the mixtures are achieved by actual pigments of vastly different physical properties, and the physics of light and the fact that her eyes take in a much broader gamut of colours than her paint is capable of mixing. A swift and nimble understanding of the relationships as geometric proportions is a solid conceptual ground that can be modified empirically as the painter’s experience with using paint and approximating it to what she sees grows. Runge (1810: 62) notes this as an aside to Goethe in one of his letters: ‘Ich kann mich hier nicht über die Praktik ausbreiten, weil es erstlich zu weitläufig wäre,’ (‘I cannot expand upon the practice here, firstly because it would ramble on too long,’) but he mentions that the artist requires ‘den nötigen chemischen wie mathematischen Kenntnissen’ (‘the necessary chemical alongside the mathematical knowledge.’)

Such systems equip us with knowledge, and thus confidence, and in the case of colour, adequately describe and organise the material reality of paint and at the same time accommodate our subjective, perceptual experience of it. Runge (1810: 42; 61) hopes that these pure insights will permit more definite expression; he thinks that being secure in the mental connections of the elements is the only means of setting a painter’s mind at ease, in the face of such superstition and chance. It would be well at this point to remind ourselves not to take the implications of these principles too far, and thus to return to Panofsky.

Copy after Claudel, Vertumne et Pomone

For the principles of vanishing-point perspective, the mainstay of principled drawing, are, indeed, a construction devised during the Renaissance, as Panofsky (1991 [1927]: 27) notes early on. It provides us with a mathematical space that is actually at odds with our perceptual experience of space, but that does not undermine its usefulness to us. Panofsky (1991 [1927]: 29-30) contrasts the visibly rigid ‘structure of an infinite, unchanging and homogenous space–in short, a purely mathematical space’ with ‘the structure of psychophysiological space.’ Our working concept of perspective demands that space conforms entirely to reason, that it is ‘infinite, unchanging and homogeneous’ (Panofsky (1991 [1927]: 28-9); but that demands certain assumptions that deny our experience of it: firstly, ‘that we see with a single and immobile eye,’ and secondly, that a flat plane adequately reproduces our curved optical image–two ‘rather bold abstractions’ from our perceptual experience.

‘In a sense,’ write Panofsky (1991 [1927]: 31), ‘perspective transforms psychophysiological space into mathematical space.’ And there is indeed nothing wrong with that if we recognise it as such, and do not take our theoretical underpinnings too far, thus over-emphasising the theoretical validity of drawing over colour.

Copy after Claudel, Vertumne et Pomone

Beginning with (helpfully visual) geometric principles, we can thus devise rigorous and teachable theoretical systems for both of the equally important parts of painting, for drawing and for colour, describing them in pure, abstracted, mathematical terms, whose constancy is beautiful in and of itself. We can reclaim the liberal art of painting, award it some intellectual prestige, and even ground it in scientific principles that draw on chemistry and physics as well. Descartes’ project might not prove so alien in the murky and superstitious realm of painting.
