Abstract
Art theory asks what artworks mean, yet this question arrives too late. Drawing on Living Value Theory’s account of symbolic fit, this article distinguishes two independent relations: mesocosmic fit (coordination with the living world of appearance, scale, materials, and situation) and intersymbolic fit (coordination with texts, iconographies, legal categories, and other symbol systems). Jan van Eyck’s Arnolfini Portrait (1434) exemplifies the distinction: extreme optical precision paired with six centuries of unresolved classificatory dispute. Read through this lens, the history of art theory, from mimesis and iconography to Panofsky, formalism, and beyond, appears as successive attempts to theorize these relations without adequately separating them. Art theory is redefined as the recursive practice that makes, disputes, and reorganizes relations of fit.
Introduction: Why "What Does Art Mean?" Starts Too Late
Every account of art theory eventually collides with the same, apparently modest question: What does a given work mean? The literature that has accumulated around that question is vast and, on its surface, disunified: debates about representation and abstraction, mimesis, form against content, expression, symbolism, iconography, artistic intention, interpretation, realism, medium specificity, aesthetic autonomy, the institutional definition of art, phenomenology, semiotics, visual studies, multimodality. Read side by side, these debates can look like separate disciplines that happen to share a subject matter rather than a single field working through a shared problem.
They are not separate. Each of them keeps colliding with the same underlying relation: the relation between an artwork, something outside the artwork, and the symbolic account through which someone tries to make that relation explicit. Living Value Theory's general account of symbolic fit supplies a way of stating this relation precisely. Before asking what a symbolisation means, ask what it fits. A symbolisation can fit the living world it coordinates with, mesocosmic fit, and it can fit other symbolic systems, intersymbolic fit. The two relations are independent, and the capacity to draw a distinction within either of them is never, by itself, evidence that the distinction was already present in the object being described.
No painting demonstrates the stakes of this distinction more starkly than Jan van Eyck's small oak panel of 1434, now known as the Arnolfini Portrait. For nearly six centuries, scholarship has tried to settle what the painting shows: a marriage, a betrothal, a legal transfer of authority, a memorial for a dead wife, a domestic scene with no ceremonial content at all. Each proposal arrives with real erudition, gathers adherents, and eventually collapses under counter-evidence the painting itself seems to keep generating. The painting is at once the most visually determinate object in the early history of oil painting, every fold, every strand of fur, every reflected surface resolved with obsessive precision, and one of the most institutionally undetermined, six hundred years of disagreement about what its central gesture actually accomplishes. That combination, extreme visual precision paired with persistent classificatory difficulty, will recur throughout this article as the clearest available test of the distinction between mesocosmic and intersymbolic fit, used not as an isolated puzzle but as the thread tying the article's separate sections together.
It is worth being explicit from the outset about what kind of claim this is and is not. Nothing that follows proposes to settle what the Arnolfini Portrait actually shows, a question that remains, properly, a matter for archival and iconographic research and not for a theory of symbolic fit to adjudicate from a distance. What the fit framework offers instead is a redescription of why that research has taken the shape it has, six centuries of proposals rather than a single settled finding, and a set of concepts that make the shape of that difficulty explicit rather than treating it as a scholarly embarrassment waiting to be corrected.
Set against this test case, the article's governing question becomes: what if the history of art theory is largely the history of attempts to theorise these different kinds of fit without adequately distinguishing them?
1. The Two Relations Art Theory Cannot Avoid
Mesocosmic fit concerns how an artwork coordinates with the living world: visible appearance, bodily scale, spatial organisation, material properties, social relation, remembered event, dwelling, historical situation. Intersymbolic fit concerns how an artwork coordinates with other symbolic systems: a textual narrative, an iconographic convention, a theological doctrine, a legal category, a piece of criticism, another artwork. Neither axis reduces to the other, and excellent standing on one guarantees nothing about the other, a claim already established as foundational for symbolic fit in general and now specified for the case of art.
Selectivity governs mesocosmic fit from the start. Zeuxis's famous grapes, painted so convincingly that birds are said to have pecked at them, fit visual appearance without fitting taste, smell, weight, or the slow process of ripening and decay. A portrait can fit a sitter's face with total confidence while telling an observer nothing determinate about that person's inner life. Van Eyck's Arnolfini interior fits the play of daylight across brass, fur, and glass with a precision that borders on the forensic, while remaining entirely silent on what the two figures standing in that light are actually doing together.
Intersymbolic fit works along a different axis entirely. A medieval Crucifixion may have negligible archaeological fit with first century Jerusalem while achieving extremely high fit with an already stabilised body of Christian iconographic and theological convention: this is the Cross, this is Mary, this posture signifies grief rather than fainting. Arnolfini, by contrast, exhibits the opposite profile along at least one crucial dimension. Its central gesture, the joined hands, the raised right arm, activates the visual grammar of witnessed ceremony, formal attestation, oath, without corresponding determinately to any single documented ritual of the period. The gesture achieves high pictorial specificity and correspondingly low fit with the legal and liturgical categories later interpreters have tried to sort it into. A Crucifixion with weak mesocosmic and strong intersymbolic fit, and Arnolfini with a comparably strong mesocosmic fit and comparably weak intersymbolic fit along its most contested dimension, will recur throughout what follows as the article's structural backbone.
The two profiles are not exhaustive, and most artworks occupy positions between them rather than at either extreme. A nineteenth century photograph of a public event can achieve extraordinary mesocosmic fit with the visible scene it records, every face, every posture caught with mechanical fidelity, while remaining almost entirely undetermined with respect to what the event meant to those photographed, information the photograph was never built to supply and that a caption, itself a further act of intersymbolisation, must subsequently provide from outside the image. A heraldic device, by contrast, can achieve very high intersymbolic fit with a family lineage and a set of legal claims to land or title while having essentially no mesocosmic relation to any visible scene at all, since a coat of arms does not depict anything in the ordinary sense. Holding these cases alongside the Crucifixion and alongside Arnolfini establishes the range the rest of the article will work within: fit is always a matter of degree along two independent axes, not a binary property an artwork either possesses or lacks.
2. Mimesis: Art Theory Begins with Mesocosmic Fit
Classical accounts of mimesis are usually rehearsed as a prelude to later, more sophisticated theory. Read through the lens of fit, the earliest recorded art-theoretical anecdotes already state the central problem with unusual clarity. Zeuxis paints grapes so convincingly that birds attempt to eat them. Parrhasius paints a curtain so convincingly that Zeuxis, arriving to inspect the work, asks that it be drawn aside. Both anecdotes are usually read as celebrations of illusionistic skill. They are more precisely read as demonstrations that mimetic success is always dimensional rather than total.
The painted curtain fits optical expectation closely enough to coordinate a practised viewer's perceptual habits along exactly the dimension the anecdote isolates, the visual cue that indicates fabric hanging over a surface. It does not thereby become a curtain, nor does it fit weight, texture, or the way real fabric moves in a draught. Realism, on this account, is the deliberate prioritisation of particular dimensions of mesocosmic fit over others rather than high fit taken generally, a prioritisation that differs by period, genre, and purpose. Caricature demonstrates the same principle from the opposite direction: a caricature can have extremely poor geometric fit with a sitter's measured proportions while achieving unusually high fit with that sitter's recognisable social bearing or characteristic expression, precisely because the caricaturist has chosen which dimensions of mesocosmic coordination to intensify and which to abandon.
Van Eyck's interior in Arnolfini pushes the same logic to an unusual extreme. The brass chandelier, the convex mirror, the individual strands of the small dog's coat, the oranges on the windowsill are rendered with a fidelity to optical appearance that few paintings before or since have matched. This is mimetic achievement of an exceptionally high order along the specific dimensions oil paint could, by 1434, be made to differentiate: surface, reflection, light, texture. It is not thereby achievement along every dimension a viewer might want a painting to supply, and the gap between these two claims, precision along some dimensions and precision generally, is the first recurrent confusion this article sets out to track. Art theory has repeatedly converted a demonstration of selective mesocosmic fit into a categorical claim about representation as such, as though a painting that achieves extraordinary fit along one axis must thereby have settled every question a viewer could ask of it.
3. Iconography: The Engineering of Intersymbolic Fit
Somewhere between does this image resemble something and what does this image mean lies a distinct and much older art-theoretical achievement: iconography, the deliberate construction of stable conversion rules between pictorial motif and narrative or doctrinal content. A woman holding a wheel becomes Saint Catherine. A figure holding keys becomes Peter. A winged lion becomes the evangelist Mark. None of these identifications depends primarily on resemblance between the image and a mesocosmic referent, since none of the apostles left a verified likeness for later painters to fit. They depend instead on relations among symbolic systems: a pictorial attribute stabilised by repetition until it reliably triggers a specific textual and doctrinal identification for any suitably trained viewer.
Iconographic traditions are, in the vocabulary developed elsewhere for symbolic fit generally, engineered fit systems, comparable in function to a diagnostic manual or a legal definition. Fit here is built, through repetition, workshop transmission, ecclesiastical instruction, and eventually formal cataloguing, rather than simply found, and it works remarkably well precisely because its conversion rules are stabilised independently of any single artist's intention.
Arnolfini deploys exactly this apparatus while withholding the stability that ordinarily accompanies it. The single lit candle in the chandelier has been read as a symbol of the presence of Christ, of the marriage vow, of ordinary domestic illumination, or of human life understood as a finite flame. The small dog has been read as an emblem of marital fidelity, as an ordinary luxury pet appropriate to the household's wealth, or, less commonly, as a memento of mortality. The oranges, imported at a cost exceeding a skilled craftsman's monthly wage, have been read as references to fertility, to paradise regained, to the couple's Mediterranean trading connections, or simply as an unmissable display of purchasing power. Each of these readings draws on an authentically attested iconographic convention elsewhere in fifteenth century painting. None of them converges on a single determinate meaning here, because the painting activates several engineered conversion rules simultaneously without providing the contextual signal that would ordinarily indicate which rule governs this particular scene. Iconography works so well in its home territory that it creates a standing temptation to assume every pictorial element must eventually resolve into a stabilised symbolic assignment. Arnolfini is where that temptation meets its most instructive failure, and the failure is instructive precisely because iconography's engineered fit is real, not because the method itself is somehow defective.
The same pattern recurs, less dramatically, wherever an iconographic convention is applied outside the narrow context in which it was originally stabilised. A halo reliably signals sanctity within a devotional image and signals nothing determinate at all when it later reappears, drained of its original theological content, as a decorative motif in secular design. A raised hand with two fingers extended reliably signals blessing within a specific liturgical context and can, in a different composition, signal only address, emphasis, or the beginning of speech. Iconography's engineered fit is always local to the symbolic ecology that stabilised it, and its apparent portability, the sense that a lion simply means Mark wherever it appears, depends on contextual cues that are themselves doing unacknowledged work. Arnolfini supplies those cues so sparingly, and activates so many candidate conventions simultaneously, that the local stabilisation iconography ordinarily provides never quite takes hold.
4. Iconology and the Dream of the Fully Sayable Image
Erwin Panofsky's 1934 essay on the painting remains the single most influential document in its interpretive history, and it deserves to be read as the paradigmatic instance of a much broader ambition within twentieth century art history: iconology, the attempt to widen iconographic method into a comprehensive account of a work's cultural, intellectual, and doctrinal meaning. Panofsky proposed that the scene records an actual marriage rite, conducted informally within the couple's own household, with Van Eyck himself serving as one of the legally required witnesses, his presence certified by the inscription above the mirror, Johannes de eyck fuit hic, and by the two small reflected figures standing in the doorway behind the couple. On this reading nearly every object in the room becomes a piece of legal or sacramental apparatus: the single candle as the nuptial candle prescribed by contemporary ritual, the removed shoes as a token of the sanctity of the ground on which a vow is taken, the dog as an emblem of the fidelity the vow establishes.
The reading was extraordinarily productive. It widened the symbolic ecology surrounding the painting, drew fifteenth century legal and devotional practice directly into art-historical method, and demonstrated, more effectively than any single piece of formal analysis could, how much interpretive weight a painting's material details might be made to bear. It also demonstrates, with unusual clarity, a characteristic hope running through iconology as a discipline: that with sufficient contextual reconstruction, an image can eventually be rendered into an increasingly complete verbal account, one that approaches, asymptotically, full propositional equivalence with what the painting shows.
This hope runs against a caution symbolic fit makes explicit. Intersymbolic expansion is not automatically recovery. A destination system, here the discursive, argumentative prose of art-historical interpretation, can generate far more explicit differentiation than its pictorial source ever stabilised, and the sophistication of that expansion can feel like discovery even where it is, in significant part, production. Panofsky's reading is many pages long, closely argued, and grounded in solid period evidence about marriage custom. None of this demonstrates that the painting's own pictorial differentiation already contained the specific legal classification the argument arrives at. Subsequent archival research has in fact weakened several of the reading's supporting details, no contemporary source confirms the informal domestic marriage rite Panofsky describes, and the identification of the sitters with a couple who, according to surviving records, may not have married until 1447, thirteen years after the panel was painted, has never been resolved. What the case shows is that the more sophisticated an interpretive apparatus becomes, the easier it becomes to mistake the precision of the interpretation for the precision of the artwork along the same dimensions, rather than that Panofsky reasoned badly, since a persuasive, well-evidenced argument and a pictorially determinate source can look, from inside the argument, exactly alike.
5. Formalism: Stop Translating the Painting
Formalist criticism, developed largely in reaction against exactly this kind of expansive iconological reading, can be understood as a disciplined response to intersymbolic overreach. Its characteristic instruction, look at the painting, amounts to a demand that translation into narrative, biography, doctrine, or legal classification be suspended long enough to register what the work differentiates pictorially in its own right: line, colour, mass, surface, rhythm, the internal relations among painted forms considered independently of what those forms are taken to depict or symbolise.
This is a real achievement, arrived at without the vocabulary developed here but tracking exactly the insight that vocabulary makes explicit: symbolic systems possess different differentiating affordances, and a painting's own affordances are not exhausted by whatever a verbal account subsequently manages to say about it. Applied to Arnolfini, a formalist reading would want to isolate precisely what Panofsky's account tends to pass over on its way toward legal and sacramental content: the extraordinary internal rhyme between the curved brass of the chandelier and the curved glass of the mirror, the chromatic relation between the man's dark red robe and the woman's saturated green, the way the room's converging orthogonals organise the eye independently of any narrative the room is supposed to be staging.
Formalism, however, risks the opposite error the moment it treats this isolation as complete. Line, colour, mass, and surface are never merely internal formal relations existing apart from a world. They are perceptually encountered by an embodied viewer, materially instantiated in ground pigment and oil, bodily scaled to a room a person could actually stand in, and historically situated within a household whose wealth, trade connections, and social position the very materials on display, imported fur, imported fruit, imported carpet, cannot be separated from. Iconology over-translates, converting pictorial differentiation into more propositional content than the source can support. Formalism, pursued to its logical end, over-isolates, protecting the artwork from intersymbolic overreach by treating its mesocosmic relations as though they were optional context rather than a second, equally indispensable axis of fit. The theory of symbolic fit developed here avoids both errors by insisting from the start that mesocosmic and intersymbolic fit are independent axes that must both be tracked, not a hierarchy in which one can simply be substituted for the other.
6. Differential Precision: Why a Painting Is Not a Sentence
Different symbolic systems possess different differentiating affordances, and no system exists that can receive every other system's distinctions without residue. Painting can differentiate simultaneous spatial relation, exact scale, resemblance, colour, material texture, gaze, bodily posture, and proximity with a precision no sequential verbal description matches. Language can differentiate negation, tense, conditionality, quotation, explicit attribution, and reported speech with an efficiency no static image approaches. The two systems are not arranged along a single scale from vague to precise. Each is precise differently, and the mistake art theory has repeatedly made is to ask which system is more precise overall rather than asking what each system is precise about.
Arnolfini isolates this principle with unusual force. The central gesture, the man's right hand raised, the woman's hand resting in his open left palm, is pictorially unambiguous in every dimension a painting can specify: the exact angle of the wrist, the precise disposition of the fingers, the relative height and orientation of the two figures. What the gesture is not pictorially unambiguous about, because painting was never built to differentiate this, is its institutional classification. A raised hand of this kind could accompany an oath, a greeting, a blessing, a declaration, or a simple gesture of address, and fifteenth century viewers, like modern scholars, would have needed information from outside the picture, a spoken formula, a documented ritual sequence, a legal witness's testimony, to determine which. The painting states exactly that two people are joined by the hands in a particular configuration. It cannot, and structurally could never, state on its own which propositional category, marriage, betrothal, oath, greeting, that configuration belongs to. Pictorial precision does not entail propositional precision, and the converse holds equally: a written record stating plainly that two named individuals married on a given date says almost nothing about how the room, the light, the clothing, or the bodies actually looked, exactly the differentiation Van Eyck's panel supplies in such overwhelming abundance.
7. The Arnolfini Portrait: Where Art Theory Meets Intersymbolic Misfit
The painting therefore supplies the article's central case in the fullest sense, not as an isolated puzzle to be solved but as a demonstration, worked out across six centuries of scholarship, of what happens when extremely high mesocosmic fit is paired with persistently low fit against every institutional and linguistic category later interpreters have tried to apply.
The historiography is unusually well documented because each new reading has been recorded, dated, and answered by the next. Panofsky's 1934 marriage certificate reading dominated scholarship for decades. Linda Seidel subsequently stressed the painting's commercial and mercantile context over its sacramental content. Margaret Carroll argued the scene depicts not a wedding but a legal transfer of authority within an already existing marriage, the man granting the woman power to act on his behalf during his absences on business. Edwin Hall proposed the scene records a betrothal rather than a wedding proper, a distinct legal category in the period with its own conventions. Margaret Koster read the painting as a memorial commissioned after the woman's death, noting the documentary uncertainty around the sitters' identities and marriage dates. Craig Harbison emphasised sexuality and social performance over any single legal classification. Each of these readings is produced by a properly trained scholar working from real archival and iconographic evidence. Each has, in turn, been challenged by counter-evidence the painting itself seems to keep generating: there is no ring visible anywhere in the scene, there is no priest, the setting is a private bedroom rather than a church or public hall, the hand-joining is performed with the left hand rather than the right, unusual for a formal marital rite, and the two small figures reflected in the mirror cannot be securely identified as anything more specific than witnesses of an unspecified kind.
Technical examination of the panel adds a further, physical layer to this difficulty. Infrared reflectography has shown that Van Eyck altered his own underdrawing as the composition developed, adding the dog, the chandelier, the chair, the string of beads, and the discarded shoes only as the work progressed rather than including them from a fixed initial plan. The perspective, closely studied, is subtly inconsistent, the chandelier is too large for the room it hangs in, the bed too short for the figures beside it, adjustments that indicate Van Eyck prioritised visual plausibility and compositional balance over strict geometric accuracy at exactly the points where a documentary reading would want the room's construction to be most reliable. None of this shows carelessness. It shows a working method in which the room's furnishings were being composed for pictorial effect during the act of painting rather than transcribed from a fixed prior scene, which weakens, without eliminating, any reading that treats the panel as a neutral record of a specific, already-scripted event.
The convex mirror at the centre of the composition adds a final complication that bears directly on how the ambiguity is experienced rather than merely documented. It reflects the backs of the two principal figures and, beyond them, two small figures standing in the doorway, positioned structurally where an actual viewer standing before the panel would be standing. The mirror is pictorially exact about this reflected doorway scene down to the individual folds of the reflected figures' clothing. It is not, and cannot be, exact about who those figures are or what role they occupy, guest, further witness, the painter himself, or a viewer's own implied position within the room. The device that ought, on a documentary reading, to supply the clearest confirmation of witnessed ceremony instead extends the painting's intersymbolic ambiguity to the question of who is watching, and from where, adding a further dimension along which pictorial precision and institutional determinacy come apart.
Symbolic fit supplies a description of this historiographical pattern that does not compete with any of the individual archival arguments above but reframes what persistent disagreement of this kind is evidence for. The conventional assumption running through the literature is that the painting contains one determinate answer, and that scholarship simply has not yet reconstructed it with sufficient precision. An alternative and more modest possibility is available once mesocosmic and intersymbolic fit are held apart: the difficulty may lie not in the painting's pictorial content, which is, on every point relevant to the dispute, exceptionally well preserved and exceptionally well studied, but in the mapping between that pictorial content and the legal or sacramental categories later viewers keep trying to sort it into. The hand relation is pictorially exact. Whether that exact relation constitutes an oath rather than a betrothal, a greeting rather than a legal transfer, is not a pictorial property in the same sense, because those categories belong to a juridical and linguistic vocabulary the painting was never built to make determinate. This is intersymbolic ambiguity in its clearest available form: the ambiguity arises because the destination classificatory system demands a distinction, marriage or oath, ceremony or transfer, that the pictorial source, however exact along its own dimensions, never made.
This reframing carries a specific and testable implication, one that distinguishes it from a merely deflationary shrug at continued disagreement. If the difficulty is truly intersymbolic, further archival discovery about fifteenth century marriage custom in general should not be expected to resolve the dispute, because no amount of general contextual reconstruction supplies the one thing the painting itself withholds, an unambiguous pictorial marker distinguishing this specific ceremony from its neighbours. What might resolve the dispute is evidence external to the categories being disputed altogether, a surviving contract naming the sitters and the occasion, for instance, which is precisely the kind of evidence six centuries of searching have failed to produce. Interpretive proliferation of the kind this painting has generated can therefore indicate persistent intersymbolic misfit between a highly differentiated pictorial source and the linguistic and institutional categories through which interpreters have tried to settle it, rather than an inexhaustible reservoir of hidden semantic content waiting for a sufficiently perceptive reader. This is among the strongest claims the fit framework makes available for art theory generally, and it deserves to be stated with appropriate caution: the claim is heuristic rather than ontological, a redescription of why the dispute has the shape it has, not a fresh archival discovery that settles which reading is correct. It asks the discipline to distinguish two very different research programmes that have so far been run together, continuing to search for evidence that would settle the classification, which remains entirely legitimate, and recognising that the absence of such evidence after six centuries is not necessarily evidence of scholarly failure.
It is worth noting, in passing, that this same painting has elsewhere been approached through a different but compatible vocabulary, one built around money, closure, and remainder rather than fit, and arrives at a structurally similar conclusion from another direction. Money, on that account, is among the most thoroughly engineered intersymbolic systems humans have built, designed specifically to close a transaction without leaving any relational residue behind. The painting's persistent refusal to be classified, on that same account, is what remains once every attempt at such closure has been made and has failed to hold. The two vocabularies name the same structural fact from different entry points: an object that achieves very high engineered fit on one register, its status as a valued, authenticated, transactable commodity, while sustaining very low fit on another, its status as a determinate record of a specific kind of event.
8. Christian Art as Re-symbolisation
Christian painting generally exhibits a symbolic structure unlike the mimetic problem examined in section two, because the artist's primary source is very often already thoroughly symbolised before the artist ever picks up a brush. No painter working on a Crucifixion had mesocosmic access to Golgotha. What the painter had instead was scripture, exegetical commentary, liturgical practice, sermon literature, and an existing pictorial tradition, each layer depositing further intersymbolisation onto the last. The relevant chain therefore runs through event, oral narration, canonical text, exegesis, liturgy, prior image, and only then to the new artwork, before art-historical interpretation adds a further layer on top, rather than running directly from world to artwork.
A painter depicting the martyrdom of a saint whose only surviving record is a written vita composed centuries after the fact faces exactly this structure at full scale. Nothing in the text specifies the saint's face, build, or precise bodily posture at the moment of death. The painter must nonetheless supply all of these, drawing not on the vita directly but on an accumulated pictorial tradition of martyrdom scenes generally, itself already several removes from any original event. What looks, to a later viewer, like a direct depiction of a historical death is in fact the current layer of a very long chain of successive intersymbolisation, each layer adding pictorial determination the previous layer never supplied and could not have supplied.
This means their mesocosmic fit operates on a different object than the original event, rather than that such paintings lack mesocosmic fit altogether, taking an already symbolised content and giving it renewed sensory and material density: bodies, wounds, drapery, architecture, weather, light, individual faces. Arnolfini contains a striking, compressed instance of exactly this structure within an otherwise secular commission. Around the circumference of the convex mirror at the centre of the composition, Van Eyck has painted ten tiny scenes from the Passion of Christ, rendered with the same obsessive fidelity as everything else in the room despite their minute scale. The most theologically absolute transaction available within Christian cosmology, the sacrifice understood to redeem all of humanity, is present in this painting, and it is present as a miniaturised, peripheral detail circling the frame of a device whose central function is to reflect the room's own commercial and domestic furnishings back into the scene. The dense intersymbolic inheritance that organises an entire altarpiece elsewhere in this same period has been compressed here into a decorative border, still legible, still theologically freighted, and no longer structurally central to the composition it inhabits.
9. The Renaissance as a Crisis of Fit
The Renaissance is conventionally narrated as a return to realism after the relative pictorial schematism of the preceding centuries. The fit framework suggests a more precise description. Renaissance painters inherit an already extraordinarily dense body of stabilised Christian symbolic content, iconographic attribute, narrative sequence, doctrinal reference, largely unchanged in its basic vocabulary from medieval devotional practice. At the same time, pictorial technique across the period intensifies mesocosmic fit at an unprecedented rate: linear perspective organises coherent optical space, anatomical study grounds bodily proportion in observation, oil glazing renders surface and light with new fidelity, portraiture individuates faces rather than schematising them, and landscape becomes topographically specific rather than generic. A donor portrait from a century earlier typically renders the donor's face as a generic, largely interchangeable type, kneeling at the margin of a devotional scene whose theological content the donor's own features do nothing to specify. A Renaissance donor portrait, by contrast, individuates the sitter's face with enough precision that later scholarship can sometimes identify the person by name from the painting alone, an intensification of mesocosmic fit occurring inside a devotional format whose theological content, and therefore whose intersymbolic obligations, remain entirely unchanged.
Two axes are therefore amplified simultaneously, an inherited intersymbolic structure of very high stability and a rapidly intensifying mesocosmic determination, and the combination generates a productive tension the fit framework predicts rather than merely observes after the fact. The more concretely rendered the depicted world becomes, the harder it is for inherited symbolic categories to control every dimension of what is now visible in such detail. Northern Renaissance painting, working in oil rather than the tempera still dominant further south, pushes this tension especially far, and Van Eyck sits at its furthest reach. He is not merely realistic in the loose sense that word usually carries. He intensifies mesocosmic pictorial determination in the Arnolfini interior to a point at which the inherited symbolic categories, marriage, oath, witnessing, that the room's furnishings and the figures' gestures ordinarily support elsewhere in period painting cease to hold the scene together with any stability. The panel's celebrated precision is, on this reading, a direct structural consequence of exactly the historical tension the Renaissance as a whole was working through, rather than something incidental to its interpretive difficulty.
10. Art as Productive Intersymbolic Misfit
Most institutional symbolic systems are engineered to maximise fit. Traffic signage wants reliable, unambiguous instruction. Legal classification wants stable, defensible categories. Scientific notation wants controlled, lossless conversion between representation and calculation. Art frequently does something else entirely. A poem becomes more interesting precisely because paraphrase never exhausts it. Music can be extraordinarily differentiated along its own internal dimensions while resisting propositional description almost completely. A painting can invite verbal classification and simultaneously withhold the specific differentiation that would let any single classification settle the matter.
The common claim that art resists interpretation should therefore be restated more precisely. Arnolfini has not resisted interpretation. It has generated six centuries of interpretation, an interpretive productivity few other single objects in European art can match. What it resists is closure through high-fit intersymbolisation, the arrival of one verbal or legal classification that would render every further reading redundant. This resistance is not obviously a defect. A painting that straightforwardly declared, in some symbolically equivalent verbal form, this is the wedding of two named individuals on a specified date would settle the historiographical dispute immediately and would also, very plausibly, generate a much thinner body of subsequent engagement. Sustained low intersymbolic fit, held here across gesture, setting, symbolic apparatus, and inscription simultaneously, can function as a productive rather than merely regrettable property of certain artworks, keeping recursive possibilities open that a fully settled classification would foreclose.
The contrast with a painting that does achieve closure sharpens the point. A donor portrait inscribed with the sitter's name, the date, and a brief statement of pious intention achieves very high intersymbolic fit almost by design, the inscription supplies exactly the classificatory information the image itself leaves open, and once supplied, that information rarely generates further dispute. Such paintings are not thereby inferior. They are doing something different, using text to close a gap that image alone would leave unclosed, in service of a devotional purpose that depends on the donor being identifiable rather than debated. Arnolfini's inscription, Johannes de eyck fuit hic, performs the opposite operation, declaring the painter's presence with legal-sounding precision while specifying nothing about the nature of that presence, witness, guest, notary, or simply signatory, that would let the declaration actually close anything. The two paintings share the technique of inscribed self-reference. They use it toward opposite ends, one toward settlement, the other toward its indefinite deferral, and the difference between them is not a matter of degree but of what each artist was apparently trying to accomplish with the same available tool.
11. Art Theory as an Institution of Intersymbolisation
Art history and art theory are not simply commentaries standing outside their objects. They are themselves intersymbolisation machines, converting painting into prose, performance into prose, installation into prose, gesture into concept, with each successive publication adding a further layer to an already layered chain. The sequence of readings traced in section seven, Panofsky's marriage certificate, Seidel's commercial reframing, Carroll's legal transfer, Hall's betrothal, Koster's memorial, Harbison's account of social performance, is, considered as a whole, a visible record of successive acts of intersymbolisation rather than merely a list of disagreements about a fixed object, each one converting the same pictorial source into a different destination vocabulary, each one adding real new differentiation to the surrounding scholarly discourse while making no correspondingly guaranteed claim about the painting's own prior content.
This suggests a discipline of intersymbolic accountability that art theory could, in principle, adopt explicitly. Of any given interpretation, it becomes possible to ask which distinctions arrived from the artwork itself, which arrived from documentary or archival context, and which arrived from the critic's own inherited vocabulary, legal, theological, psychoanalytic, formalist, and to ask further what became more determinate through the act of verbalisation, what was compressed in the process, what disappeared entirely, and what new differentiation the interpretation actually produced that the source never contained. This connects directly to the broader warning, developed for symbolic classification generally, that a taxonomy is always a later, L4 operation performed upon practices that did not require the taxonomy in order to function, and that the taxonomy's usefulness is never, by itself, evidence that it was already latent in what it classifies. Art theory, recognising itself in these terms, would no longer describe itself as a discipline that discovers meanings already resident in works. It would describe itself, more accurately, as a discipline that produces successive new symbolisations of works, some of which achieve excellent fit with the works they address, some of which do not, and whose collective history is best read as a record of that production rather than as a slow convergence on a single settled truth.
Intersymbolic remainder is visible in this sequence as clearly as intersymbolic gain. Panofsky's reading foregrounds sacrament and law and correspondingly underplays the household's commercial context, which Seidel's reading then restores while losing some of the sacramental weight Panofsky had carefully built up. Carroll's legal transfer reading explains the raised hand with unusual precision while having comparatively little to say about the room's devotional furnishings, the Passion roundels, the single candle, that a sacramental reading foregrounds. Each successive contribution is therefore not simply additive, a growing pile of confirmed facts about the painting, but selective in the same way any single intersymbolisation is selective, gaining determinacy along the dimension it prioritises and losing some of the determinacy the previous reading had supplied along a different one. Reading the historiography this way does not diminish any individual contribution. It explains why the sequence has not converged after six decades of serious, careful scholarship, since convergence was never the kind of outcome intersymbolisation, applied repeatedly from different starting vocabularies, reliably produces.
12. A Five-Mediational Reclassification of Art History
The five mediations, embodiment, being-with, dwelling, multimateriality, and multisymbolization, are always simultaneously present in any coordination, including the coordination an artwork enters into with its viewers, and a given artistic formation can nonetheless be characterised by which of the five it amplifies and which it mutes. This offers an alternative to organising art history purely by style, medium, or chronology, without displacing those more familiar organising principles.
Classical Greek sculpture strongly amplifies embodiment and multimaterial forming, presenting the body as an object of sustained physical attention in stone or bronze. Roman monumental art intensifies multimateriality, dwelling, and multisymbolization together, embedding political and religious meaning directly into the built environment its viewers physically inhabited. Medieval Christian art places extraordinary weight on multisymbolization, dwelling, and being-with, coordinated through scripture, iconographic convention, church architecture, and collective liturgical practice rather than through individuated portraiture. The Renaissance, examined at length in section nine, becomes visible as a rebalancing rather than a simple return, an inherited intersymbolic structure meeting a rapid intensification of mesocosmic fit, and Arnolfini can be located within this profile as an unusually extreme instance, a Northern Renaissance commission in which mesocosmic intensification, embodiment rendered through material and optical precision rather than through movement or scale, reaches a point where the inherited symbolic categories of the surrounding tradition are placed under visible strain. Locating the panel within a mediational profile in this way answers a different question than locating it within a documentary dispute about marriage law, not what specific event the room records, but what kind of coordination between embodiment, multimateriality, and multisymbolization the painting as a whole is organised around, and it is a question the historiography traced in section seven has generally not asked in these terms, however much evidence it has assembled in pursuit of the narrower one.
Later movements admit the same kind of redescription. Impressionism amplifies perceptual embodiment and temporal immediacy. Cubism disrupts ordinary optical coherence while intensifying material and symbolic reorganisation simultaneously. Minimalism amplifies material presence, scale, and bodily encounter while deliberately muting iconographic and narrative content. Performance art intensifies embodiment and being-with while frequently resisting durable symbolic stabilisation altogether. Conceptual art can make multisymbolization itself the dominant, almost exclusive mediation, muting embodiment and material forming nearly to the point of disappearance. None of this proposes a taxonomy of five kinds of art, proposing instead a method for constructing historically specific mediational profiles, in which the relevant question is always which mediations a given formation intensifies, which it mutes, and what relations of fit it consequently cultivates or forecloses between them.
13. Iconoclasm: When Fit Becomes a Fight
Iconoclasm demonstrates that questions of fit are never merely interpretive exercises conducted at a comfortable scholarly distance. Christian iconoclasm can be read as a conflict over the legitimacy of representation organised precisely along the two axes this article has traced throughout. The iconophile argument rests on a mesocosmic claim: if the Word truly became flesh, divinity itself acquired embodied, visible existence, and the Incarnation supplies theological warrant for representing that embodiment pictorially. The iconoclast objection rests on an intersymbolic claim: scripture specifies remarkably little about Christ's actual appearance, while any image must supply hair, complexion, stature, and expression, introducing differentiation for which the textual source offers no warrant whatsoever. Stripped to its structure, the iconoclast's charge is an accusation of low intersymbolic fit between text and image, argued in theological rather than art-theoretical vocabulary.
The historical episodes bear this structure out. The Byzantine iconoclastic controversy of the eighth and ninth centuries turned substantially on exactly this objection, that painted icons of Christ either falsely claimed to depict a divine nature that admits no visible form or else depicted only the human nature at the cost of dividing what theology insisted was a single, indivisible person, an argument conducted almost entirely in terms of what an image could and could not legitimately be made to fit. Reformation-era image-breaking several centuries later drew on a related but distinct charge, that accumulated veneration of images had displaced the textual and doctrinal authority the reformers wished to restore, again a dispute over which symbolic system, image or scripture, ought to govern devotional practice. In both episodes, the theological argument and the physical destruction were not separate events loosely connected by shared motivation. The physical destruction was the argument's own conclusion, enacted because the disputed image had already become, in Aquinas's phrase understood mediationally, an object of the very veneration the argument was contesting.
The dispute becomes physically destructive rather than remaining a matter of written correction because a religious image, once it enters devotional use, becomes a material object occupying a church or shrine rather than remaining confined to multisymbolization, an object bodies kneel before, hands and lips touch, communities gather around and process with. The disputed symbolic stabilisation spreads across all five mediations simultaneously, and correcting it symbolically, at the level of doctrine alone, cannot undo what has already been sedimented materially and relationally. Arnolfini's own Passion roundels, examined in section eight, sit at the far end of this same continuum without ever crossing into it: theologically authentic, materially present, and yet so miniaturised and peripheral within a secular commercial interior that no one has ever proposed destroying the panel over their placement. The contrast is instructive precisely because it shows how much the stakes of a fit dispute depend on how far a given symbolic form has spread across the other mediations, from a decorative border legible only to a viewer who leans in close, at one extreme, to an object venerated, kissed, and processed with by an entire community, at the other.
14. So What Is Art Theory?
Returning explicitly to the question posed in the title, several familiar candidate definitions can now be set aside as insufficient. Art theory is not merely a theory of beauty, since beauty names, at most, one evaluative dimension among many a symbolic account of an artwork might address. It is not merely a philosophy of representation, since representation already presupposes exactly the single, undifferentiated relation between symbol and world that the distinction between mesocosmic and intersymbolic fit exists to break apart. It is not merely interpretation, an explanation of artistic intention, or a classification of styles, since each of these names one recurring activity within the field rather than the field's underlying operation.
The positive definition on offer is this: art theory is the recursive symbolic practice through which relations of fit between artworks, worlds, and other symbolisations are made explicit, stabilised, disputed, engineered, and periodically reorganised. Its recurring tasks, visible across every section of this article, are establishing mesocosmic fit, establishing intersymbolic fit, explaining misfit where it occurs, engineering new fit where none previously existed, policing which fit will count as legitimate, resisting excessive fit where a discipline has overreached its own evidence, translating across symbolic systems while tracking what that translation adds and suppresses, determining whether an apparent ambiguity belongs to the artwork or to the mapping being applied to it, determining which mediations are actually salient to a given case, and determining, in each instance, which of the critic's own symbolic distinctions actually belong to the work under discussion. Art theory, understood this way, is itself part of art's history rather than an external commentary appended to it, one more layer in the same chain of intersymbolisation the theory exists to describe.
Conclusion: Art Theory After Meaning
Return, finally, to the question this article opened with. What does a given artwork mean. The question is not invalid, only premature, starting too late by presupposing that a single symbolic account already awaits discovery inside the object, when the prior and more tractable question is what the object fits. What world does it coordinate with, and along which dimensions. What does it leave mesocosmically undetermined. What earlier symbolisations does it inherit before a single brushstroke is laid down. What symbolic systems does it invite translation into, and what does each translation add, what does it suppress, what does it produce that the source never contained. Where does actual misfit occur, and does a given ambiguity belong to the artwork itself or to the classificatory system being brought to bear on it.
Arnolfini answers each of these questions differently, and that difference is the whole of its interpretive history. Its mesocosmic fit with the visible world of fabric, brass, glass, and light is about as high as fifteenth century painting could achieve. Its intersymbolic fit with the legal and sacramental categories six centuries of scholarship have tried to apply to its central gesture has remained stubbornly, productively low. Art theory has spent those six centuries trying to determine what the painting means because it has lacked a prior, explicit theory of what the painting fits. Once mesocosmic and intersymbolic fit are properly separated, Panofsky's certificate, Seidel's commerce, Carroll's transfer, Hall's betrothal, and Koster's memorial cease to look like five competing answers to one question that only one of them can win. They become five separate acts of intersymbolisation, each adding real differentiation to the surrounding discourse, none of them thereby proven to have recovered a content the panel already secretly contained.
Art may be special not because it somehow escapes fit altogether but because, unlike most institutional symbolisations, it can hold mesocosmic and intersymbolic fit in visible tension, intensify both simultaneously, and refuse to let either one quietly settle the other. Art theory begins to understand its own object only when it stops asking solely what an artwork means, and asks instead what it makes fit, what it refuses to let fit, and why, six hundred years on, that difference still matters.
None of this closes the file on the Arnolfini Portrait, and closing it was never the aim. Archivists may yet find the contract, the parish record, the household inventory that finally names the occasion the painting records, and if they do, the fit framework offered here will have nothing to say against it, since an actual mesocosmic discovery of that kind settles a historical question no amount of theorising about symbolic systems could settle from an armchair. What the framework offers in the meantime is a way of understanding why six centuries without that discovery have not been six centuries of failure. The painting has been doing, with unusual persistence, exactly what a small number of artworks across the tradition seem built to do: holding two axes of fit far enough apart, for far enough long, that neither the archive nor the argument has yet been able to collapse them into one.
