Art History – Abby LaPier

Convincing (?) Art Historical Text Generation

It’s a commonly held prejudice that analyses of art are arbitrary; you can look at a piece of art, repeat any stock expression, and your audience, no matter how educated, will buy it. So when prompted to address contemporary art in some way, I decided to test that theory by submitting ten pages of randomly generated art historical text. Producing text with a Markov model raises questions about the role of contemporary art scholarship. On the most naïve level, it is a humorous exercise in seeing the actual words that art historians and critics produce. On a deeper level, however, the amount it convinces us of its veracity or potential veracity provokes two kinds of thoughts. The first, critical in nature, prompts inquiry into the extent that art criticism is derivative. If this text, which is by construction the shuffling and reprinting of previous texts convinces us to some degree, then we must wonder how “original” art historical knowledge production differs in scope. (Though one likely had this thought before reading any algorithmic output.)

The second thought is reflexive in nature: the position with which we naively approach such text is itself a meaningful metric for how we conceive of writing on contemporary art, and perhaps contemporary art itself. Though obviously silly, the model itself contains a vast amount of information, available immediately with the correct query. As such, it is not inherently dismissible; it knows more about contemporary writing on contemporary art than (arguably) any person, though it may produce nonsense. The position it provokes in its readers (scientific interest, disdain, amusement) is immediately communicative of their baseline thought on contemporary art criticism, and its underlying relationship to the art itself.

Contemporary Art

For example, two chairs in a structure of racial inequality. Is there one? To withdraw from the East River to the general culture. But, if so, you could argue that the internet is based on solidarity, on the refusal to be privatized is our bodies. Yet if police responses to Occupy encampments around the United States; it is arguably the most complicated form is metaphysical guilt: for Jaspers, guilt in the Saturday Night Live skit, The Nerds, though. The look is borderline nerdy. I remembered pantywaist, a word that comes after Art. He has spoken of the exhibition Air de Paris, Paris; Pilar Corrias, London; and Esther Schipper Gallery, Berlin, Germany. On 23 October, his solo show at 47 Canal; New York. No less than a quarter of the participating artists are likely to see. After receiving a Golden Bear at the time, were really talking about Brazilian identity. Cristina Freire: In the case of the philosophy of Deleuze, but clearly favors differentiation over repetition. He offers a sketch or a norm implicit in a book. The carbon chains, O-H3, C-H3, C-OH, gradually penetrate my epidermis and travel through the deep conservatism in neo-formalist work being created by artists much younger than her ever questionable inclusions and exclusions arise, oddball juxtapositions distract.

Methodology

Contemporary art text generation is based on a statistical model called a Markov Chain, a simple but powerful system used to model structures as diverse as the google search algorithm, grammar, the stock market, board games such as monopoly, weather, and insurance pricing. Markov models are based on three basic assumptions:

There are finitely many states the system can occupy.
There exists a probability distribution on the system that gives the conditional probability of moving from one state to another.
At each time step, the future is conditionally independent of the past.

The final assumption is what makes a Markov model meaningfully different from other ways of modeling multi-state systems. Let’s assume for the sake of didactic clarity that we want to understand how two games, blackjack and snakes and ladders, work. I can do better at blackjack if I can remember the previous cards which have been dealt. Since the dealer goes through the deck incrementally, as he or she puts down cards, the probabilities of winning at each hand change. In snakes and ladders, at each turn, my position on the board and my dice roll completely determine the probability of any outcome. Since previous dice rolls do not affect the probability of future dice rolls (i.e. they are statistically independent), and the only thing previously determined is my position on the board, each turn in snakes and ladders is conditionally independent of previous turns. Snakes and ladders can be Markov modelled; blackjack cannot.

For text generation, Markov models use the assumption that for each word (or fixed-length phrase, confusingly also sometimes called a “word”), there is a probability distribution on all the words that can follow it, which are further assumed to be finite. For example, if I say the word, “MoMA,” I might follow it with, “exhibition,” “curator,” “is,” “galleries,” etc., and each distinct word has a fixed probability of occurring. (The probability of a nonsense phrase like, “MoMA steamroller” will have probability at or close to zero of occurring.) Each pair of words is called a prefix-suffix pair. To generate text, then, we can pick any prefix we want, then randomly choose one of the suffixes that follows it, weighted with its probability, and choose one of the suffixes that follows that word, and so on. At each word, the words that follow the prefix depend only on the prefix – the future is conditionally independent of the past.

Implementation Details

The text generator was coded from scratch based on text scraped from online sources, also from scratch. I programmed the crawler and scraper in python using urllib to make http connections and BeautifulSoup, a screen-scraping library based in XML that translates web pages into trees. (I originally used these packages for a CS problem set). Based on the source code of the website, my code algorithmically generates the archival page urls which contain the urls for individual articles, then visits each article url and pulls the text, writing it to a text file. The model is built by analyzing the individual source text files.My program read the entirety of Jerry Saltz’s critical work for NYMag (about 200 articles), the entirety of e-flux (about 850 articles) and the 100 most recent issues of Frieze (about 6000 articles).

In order to generate text, we first need to build the probability distribution; the data used is called the corpus. The larger and more diverse the corpus, the better the text. For the sake of grammatical clarity, I fixed the prefix and suffix lengths to two words. This produced 275668 unique prefixes, each mapping to at least one suffix. Because the program needs a seed word to begin generation, I also compiled a list of 325 unique prefixes which begin articles. (Random example: “Separations are”.) To control length and give a stronger impression of coherency, I generated text by paragraph, ending with the last period before a newline break in the original text. Though longer paragraphs give a higher probability of having a diverse range of topics, short paragraphs have surprising diversity. This paragraph was produced with a base length of 10 words:

Why do we think it’s from smoking or the pollution, because it’s too much energy and exist only in a contemporary living room, she did spice it with his kisses. Last autumn, when I was about finding ways to buy it.

The paragraph began with “Why do”, the 99^th item in the list of starting words. That prefix has five possible suffixes: “I have”, “we reject”, “a lot”, “America and”, and “we think.” “we think,” the algorithm’s choice of suffix, maps to 12 suffixes, but “it’s from” only produces “smoking or.” Generation randomly oscillates between prefixes with widely varied suffixes and those with very limited options. Every paragraph in “Contemporary Art” was produced in this way, with a base length of 75 words.

To see the importance of a large corpus, we can compare this text to a Jerry Saltz bot. Generation with a base length of 20 words produced, “Jaccuse museums of bullshit! Of bogusly turning themselves into smash-hit consumer circuses, box-office sensations of voyeurism and hipster showbiz. This year, the Dependent debuted in a car accident in 1977, shortly before her 41st birthday. Morton combined conceptualism, postminimalism, magic, Americana, and kitsch with a feminist twist and a comedians wit.” Though equally coherent, this text is inherently restricted to Saltz’s syntax; its ability to produce diverse content is limited. (It should be noted, however, that each of the corpuses – Saltz, Frieze, and e-flux – are large enough to produce coherent text on their own.) As with all data projects, the quality of the text is limited by the quality of the data.

So, did it work?

Somewhat. Markov models, though straightforward to implement, generally don’t give the most life-like text as sentences have a tendency to meander and bare little relation to each other. In the future, I want to experiment with methods for connecting sentences to each other, perhaps by subdividing the corpus into content areas. It seems like NLP/NLG can become arbitrarily challenging, so it would be interesting to see how deep one has to go in exchange for a payoff in readability.

I submitted two documents: “Contemporary Art,” a ten-page randomly generated paper; and “Methodology.” According to my professor, “methodology sounded boring,” so he immediately read the paper and felt it was comparable to what a “bad art student” would “try to pass off as art history” but not really recognizable as an art historian’s paper. Thanks Matthew Jesse Jackson for being a supportive guinea pig and signing off on the project in lieu of actual, you know, art history.

Looking Closely at Olmec Style

How do we understand art from societies with no writing? What if that art is abstract?

This is a condensed and edited version of my BA thesis, “Smooth Sides and Shining Surfaces: Looking Closely at Olmec Style.” It won the Robert and Joan Feitler Prize for Best Art History BA and was presented at the UChicago Undergraduate Research Symposium, Spring 2014, in the “Design and Change” panel. Many thanks to Claudia Brittenham for editing and advising.

Three thousand years ago, in the modern state of Veracruz, Mexico, people living near a spring in the Coatzacoalcos basin began making offerings in the water. Now known as Olmec, they offered wooden sculptures, foodstuffs, stone and ceramic bowls, rubber balls, human remains, and jade and greenstone objects in dense patterns. Despite the complexity of the deposits, neither the people of El Manati nor other Olmec left decipherable writing in the course of the civilization, from 1500-300 B.C. Only a single piece of Olmec epigraphy survives at all. At a loss to understand how the Olmec understood their material culture, generations of scholars turned to the most legible, iconographic pieces in the archaeological record, using them as proxies for absent writing. Though sometimes productive, this methodology left vast swathes of material unstudied, functionally ignored as anti-epigraphic, anti-iconic, and therefore apparently uncommunicative. In a push to understand what objects show and what they are, we can easily lose sight of the artistic challenges built into them, encoded in apparently simple objects. In order to understand ancient cultures, we need to challenge ourselves to look closely at objects which are hard to interpret, beginning with objects which seem like there is nothing to be interpreted.

Two classes of objects, small jadeite sculptures known as celts, and white, rounded bowls known as tecomates, are ideal candidates for such study. Extremely minimal in form and design, without modeled or incised decorations, they largely occur as archaeological footnotes.¹ Treating celts and tecomates as merely simple misses a source of depth, complexity, and connectedness in Olmec material culture. Even on the surface, celts and tecomates have a sophisticated decorative program that harnesses light, shadow, glow, and materiality to individuate each item, despite overall standardization. By evoking their natural sources and facture, they access a tactility which moves beyond a simple ability to be held into and interpretive process. This physical activation melds with an intellectual process of engagement where the viewer naturally associates celts and tecomates with other objects, but is constantly aware of their innate, self-contained abstraction. Their commonalities argue for a way of understanding material evidence that moves past categorizations based on theorized symbolism and instead looks deeply at the logic of the objects themselves, revealing pieces which remain self-referential and abstract.

Though at first glance these objects appear simple, closer investigation reveals their careful composition, pointing to an important position in Olmec material culture. A cluster of jadeite celts from El Manati pair unity and individualization, complexity and simplicity. Each celt varies the elongated, trapezoidal shape of an ancient ax head, altering the sweep of the sides and curve of the base and tip to individualized proportions. They range in color from beige to mottled grey to sea foam to slate, each piece with its own grain and variations. Whereas the top left celt has a fine, sandy white grain, the rightmost celt has a diagonally oriented, swirling white grain which grades into dark, rusty clouds near the bottom. These variations in color give the illusion of undulating weights, changes in light and shadow imitated in jade. Their curving, mirror-bright finish creates shifting pockets of lightness and depth.

Similarly, tecomates’ burnished surfaces create an artificial sense of shading in which the pot appears to glow from within, elevating them beyond simple white bowls. Tecomates contrast monochromatic slip with a lustrous, mirror-burnished finish.² Creamy and shining on the exterior, black and matte on the interior: a white-slipped tecomates from the Valley of Mexico glows, harnessing undulating light and shadow. Subtle variations in the raw materials, temperature flows during firing, and fuel types create changes in fluctuations in the white color palette, a subtle compositional detail that enhances the burnished surface’s optical effects. At the widest part of the pot, the brighter beige slip grades into smoky grey clouds, set off with spots of sienna that bleed into darker grey. These irregularities carefully mimic the undulating effect of the lustrous slip. Far from randomly chosen or carelessly executed, celts and tecomates demonstrate a closely planned composition that justifies rigorous art historical consideration.

Though celts and tecomates are formally complex, their minimal composition’s position in Olmec material culture is poorly understood, leading to their canonical designation as simplified representations of other objects. Treated as skeuomorphs, their form becomes incidental and inherited. In general, an object is a skeuomorph or skeuomorphic if it replicates on material in another: for example, pottery that looks like basketry or metal, or stone that looks like textile. For want of clear imagery, round, white tecomates become ceramic copies of gourds; green, tapered celts imitate maize cobs, ax heads, or the axis mundi.³ Categorizing any object as a skeuomorph treats its meaning reductively, where an object is little more than a copy – perhaps with humorous or clever connotations – but in the end, based entirely on some outside source. Its attributes are inherited, not original, undercutting its integrity. Presupposing this relationship denies an object meaning in its own right.

These abstract objects’ lack of decoration makes iconographic classifications problematic, undercutting the effectiveness of skeuomorphism as an interpretive framework. Though objects gain canonical associations, the actual relationship between a skeuomorph and its referent is rarely explicated, as if minimalistic, white bowl is somehow naturally a gourd. The categorization circumvents significant methodological problems related to motivation, which is challenging if not impossible to reconstruct without written evidence. Further difficulties arise when presumed skeuomorphs lose decorative elements present in the originals. As anthropologist Stephen Houston writes, “Most skeuomorphs have two […] tangled features, the first that cross-media transfer is usually presumed to be unidirectional, the second that transfers often mix media or juxtapose elements in notable bricolage.”⁴ If a celt is more minimal in shape, surface, and texture than an ear of maize, it actually borrows very little from a literal ear of corn. Imposing this iconographic scheme a priori allows the desire to find symbolism to overcome the possibility that undecorated objects may represent nothing other than themselves.

Indeed, the relationships between celts and maize and tecomates and gourds are more impressionistic than definite, underscoring these problems. Scholars generally associate tecomates with gourds in part because of their unusual shape; most Olmec vessels are wider edged plates and dishes. Later Maya paintings show figures using rounded gourd vessels, with the same deep curves as a tecomates. However, since all Olmec gourds decomposed long ago, tecomates remain in an ambiguous position, as we have no idea what Olmec gourd cups really looked like, or if gourd cups were a cheaper imitation of rounded ceramics.⁵ Similarly, greenstone celts vary widely in shape, size, and color; simply put, some celts look plausibly like maize, and others do not. A unidirectional relationship between original and imitation is far from evident.

With their simplified forms and carefully produced surfaces, celts and tecomates refer to both natural source material and other related forms, engaging in multiple conceptual gestures. Sculpted from boulders tumbled through the Motagua River, celts bear a formal resemblance to their unworked source material, carrying a reference to an idealized natural object. As large boulders of jadeite tumble through fast-moving rivers, softer stone chips off, leaving roughly triangular forms known as cobbles.⁶ These cobbles are often naturally celtiform, with a wide, rounded end, and a noticeably pointed tip. Though celts reduce cobbles’ scale, they maintain and distill cobbles’ inherent triangular composition. Symmetry replaces natural variability with respect to form. The regulation of these natural asymmetries imposes an inherent sense of a human hand in an object that recalls its material source.

With a more amorphous material, tecomates do not have the same formal relationship to clay that celts have to jade cobbles. Nonetheless, their surface treatment foregrounds a luminosity unique to burnished clay, producing an object that first and foremost looks like pottery rather than an imitation of gourds. The Olmec produced many ceramic objects which painstakingly reproduce natural forms far more complex than gourds: ducks, babies, and jaguar figures, to name only a few. Therefore, by editing tecomates down to the simplest possible form, Olmec sculptors made a definite choice to not faithfully imitate gourds. Furthermore, highly burnished pottery has a surface unique among Mesoamerican materials. Its gentle diffusion of light and seemingly internally generated luminosity make any burnished pot look distinctly unlike other objects. It is not imitative of other natural surfaces, including gourds. By foregrounding their material as an essential aspect of their appearance, celts and tecomates are always bound to a fundamentally sculptural gesture which resists a representative reading. Rather than imitating another object, celts and tecomates maintain a continual tension between gourd-like and clay-like, corn-like and jade-like, problematizing their reduction to simple symbols.

Without recourse to symbolism, theorizing these objects requires a return to form and composition, drawing the pieces into a dialogue with a viewer or user. Via a manipulation of scale and shape, celts and tecomates encourage usage that mimics their facture, creating meaning that is self-referential rather than outward looking. The final piece engages the viewer both visibly and tangibly. A tecomate’s smooth curves and delicate size match the shape of an open palm. Spanning only 4 ¾ inches across and 3 ½ inches vertically, with a flattened bottom and low curves, the tecomate pictured above would nestle exactly into a slightly open palm, with the thumb and fingers brushing the sides.⁷ On contact the highly burnished walls are silky smooth to the touch. This attention to personal scale, coupled with the undulating patterns of light and shadow on the surface, underscores that tecomates communicate primarily as abstract objects, not iconographically.

Both objects evoke their facture in form through their elongated, trapezoidal shape, creating a self-referential dialogue with the viewer. True jadeite was the hardest material known in Mesoamerica; creating celts was an extended and intensive process.⁸ Initial blocks were separated from boulders with percussive strokes, then chipped into a rough version of the final form. With repeated grinding from an abrasive such as jade or quartz sand with a wooden or stone saw, rope, or drill, a simplified, trapezoidal form emerged. ⁹ In the case of ceramic, since Mesoamericans did not have pottery wheels, tecomates were assembled from a flat base and coils of clay shaved into a smooth curve. Repeated scrapings with a stone or smooth implement, over the days required to harden from leather-hard to the firing stage, created the final lustrous and smooth surface. In both objects, once the first rough form emerges, the two follow parallel processes of reduction, first in large chunks of material, and then in a slow, painstaking smoothing and shaping. These artistic manipulations create shining, luminous surfaces that the naturally holds and touches.

Stroking motions naturally are firmest at the point of contact, smoothly decreasing in pressure until the hand lifts away. This gesture congeals in celts and tecomates’ elegantly tapering and curving forms. In this sense, they connect the current feel of their surface with the previous touchings that created their surface and form. Their form becomes tactile through its solidification of a physical process. Tactility is therefore interpretive: a viewer recognizes it in a form, and understands it as part of a process. Moreover, this interpretation is bidirectional. Responding physically to a piece prompts a to wonder about the hands the made it, and understanding the process of shaping a piece calls out for the replication of that process via touch. This self-reference operates entirely outside of iconography.

Tactility, viewer engagement, and self-referentiality come to the forefront in an expanded view of Olmec material culture, demonstrating the theoretical possibilities of frameworks that operate without reference to iconography. A large burial site at Tlatilco, in the Valley of Mexico, contains hundreds of graves, each with a mixture of pottery, bones, musical instruments, figurines, among other objects.¹⁰ Ceramics rest in every grave.¹¹ Beyond simple ubiquity, however, the pots nestle into bodies, with other sculptural objects at a greater distance. Graves show pots between legs and tucked under arms, with figurines set apart by as much as a foot, a relatively large distance in a small burial. Though graves do not perfectly demonstrate how living Olmec related to their pots, they do encode significant indicators of social practices.¹² Such depositions gesture at the importance of tactility and touch in Mesoamerican contexts.

Though semiotic interpretations provide an easy starting point for schematizing ancient materials, they either exclude abstract objects as unreadable, or attempt to impose iconography where it cannot fit. Both methodologies deny sophisticated, conceptual artworks autonomy in their own right. They tacitly position ancient, abstract art as less realized, unable to produce its meaning independently. Despite this historiography, minimal Olmec objects do afford closer readings that reveal complex connections between the pieces, their facture, and their viewer. Importantly, these connections extend beyond close readings of individual objects, using abstract pieces as a new theoretical framework for ancient art.
