The Scene of Disciplined Seeing

Shanti Morell-Hart

“What is the most AMAZING thing you’ve ever found?” This is the question dogging archaeologists, right now, this very second, while we sit on planes, wait in doctors’ offices, and visit school classrooms. There are two common types of answers: the sensational kind, and the kind with intellectual merit. If you’re lucky, these overlap in a perfect Venn region, maybe something like an ancient golden statue depicting rare sexual acts in Pharaonic Egypt (that also happens to transform the way we understand ancient Egyptian sexuality and expands the known range of gender performatives).

I used to go for intellectual merit right off the bat. I’d start: “One time, I found this really old Nicotiana seed—that’s tobacco, maybe tabacum or rustica—it was a lot stronger back then, not like the stuff now that people smoke for fun. Anyway, it was in this flotation sample I was sorting through—really beautiful reticulated surface, there’s no mistaking it….” I’d trail off, lamely. I would see vague disappointment shifting into obvious disappointment. The Latin binomials were alienating; also, smoking kills. I’d clear my throat and give it another try: “Uh, so there was also this time where I was excavating a tomb with a team in Peru and we found a sacrificed baby llama that still had a leash around its neck….”

Somehow it’s easier to explain life-sized things than microscopic things, to talk from a shared mind’s eye. It’s easier to evoke a scalar perspective-in-common, where you’re staring at something the listener can (virtually) point at and poke at along with you. It’s also easier to generate interest in the kind of findings that would hit tabloids if they took place in the contemporary world.

For paleoethnobotanists, it can be hard to express the excitement of the find. What gets us into it? In my case, I was interested in food, I wanted to be able to analyze food residues myself, and I didn’t want to deal with roadkill for my reference collections (so sorry, zooarchaeologists). This meant learning the trade of paleoethnobotany, with long hours at the microscope and a rich payoff in plants.

Plant payoffs, moving from the microbotanical to the practical:

The work of paleoethnobotany takes place at many scales: the monumental (wooden Viking longboats), the macro (woven yucca sandals), the micro (grass starches on Neanderthal teeth), and the chemical (theobromine signatures of chocolate). For those of us lodged at the microscopic level– a realm of seeds, phytoliths, pollen, and starch grains– the practice of archaeology holds a special set of practices and problems. We experience back pain, eye strain, headaches, tendonitis, and even ganglion cysts. Health issues related to the ergonomics of microscope use can be found in a variety of places) but the neurological effects are less well documented. I suspect a wide range from mild discomfort to madness.

But the visceral experience of microscopic practice is not all discomfort and tedium. We are also drawn into exotic and mysterious worlds. The first time I peeked into a microscope while sorting flotation residue, I felt like Jacques Cousteau. My god, the things in dirt. We take germs on faith and most of us have seen earthworms up close. We know–or are pretty sure we know–those things are in there. But there is so much more to see. Never mind the chemistry of it all, which is way outside my pay range.

Macrobotanical under microscope
Charred wood, seeds, insect legs, modern rootlets, egg casings, and god knows what else, in a macrobotanical flotation sample.

If looking at flotation samples is like scuba diving, studying microbotanical remains is like flying through another galaxy. Extracted sediment and artifact residues, suspended in liquid and mounted on slides, present strange psychedelia. Acrocomia mexicana endocarp phytoliths appear as planets; Zea mays starch grains as 1960s beanbag chairs.

Visually, you feel suspended alongside the residues. Your eyesight becomes disarticulated from the regular workings of your body. An awkward shift in physicality takes place. Your normal manual dexterity is fitted with giant clown hands to manipulate objects smaller than you can see with the naked eye. Trying to get silicified plant cells to roll over, to view their 3-D morphology, involves some measure of agility and some measure of luck. Gently depressing the slide with a blunted probe will sometimes get phytoliths to rotate, but not always. Yelling at the slide is futile. The last thing you need is to turn the microremains against you.

While at the microscope, the miniscule becomes “life-sized,” and you experience a set of layered realnesses. You sense an envelope of lab smells (dust, mysterious liquids evaporating from jars, someone’s leftover pasta cooking in the microwave), gossip (who shortchanged who last beer night), podcasts and music (strains of Finntroll coming from the speakers), temperature (always overly warm). But your eyes are in another place, a here and not-here; or two half-real places. It’s almost like playing a videogame. Although the meatspace houses the bodily you, sitting at a microscope, your findings are actually taking place in an entirely different location: microscospace.

The “scene of disciplined seeing” (to borrow a phrase from Dennis (1989:342) is part embodied discipline, with all the necessities of proper posture and focus. It is also part disciplinary perspective, with all its rules, affordances, expectations, and perspectives. Early use of the microscope by the 17th century British Royal Society was a unifying endeavor. If we are to believe Robert Hooke, it was a way of “exceeding the Ancients” through scientific labor. At that time, according to Michael Dennis, “instruments imparted a distinct sense of the past and the future, uniting men holding otherwise diverse philosophical positions” (1989:310). Modern archaeologists, however, take to this same instrument intending to connect the past with the present, and our pursuits can divide people holding otherwise similar philosophical positions. (One example: the current philosophical centrification of STEM disciplines [including archaeological science] across political divides, yet persistent denial of evidence of anthropogenic climate disruption recovered by these same disciplines.)

What is the role of disciplined seeing outside of archaeological science? Early appetites for micrographic images—Hooke’s 1665 volume Microphagia was a certified bestseller—are not what they once were. The fruits of disciplined seeing are no longer exclusively harvested through the magnanimity of the Royal Society. Basic instrumentation has become affordable. Gentlemen scholars under moneyed noble patrons are no longer the sole gatekeepers of every microscopic finding. The ready availability of scientific instrumentation has helped to democratize scientific practice, and microscopic images can even be captured and posted using smartphones.

These are all welcome changes. But the “watering down” of academic imagery has made it harder to evoke the excitement of archaeological science through the simple presentation of pictures. Representation, through interpretation, helps to elicit such excitement. This is not a simple process. Representation is subject to other rules and expectations, including those of anthropology and the public. Ultimately, our seeing is disciplined by visual, experiential, academic, and political fields, and our findings are only as relevant as our audiences allow them to be.

So how can we recapture that magical Venn region where the sensational and the academic merge? Maybe the answer is “blog posts.”

Disciplinary Vision, Disciplined Seeing, and New Technologies of Enchantment

Andrew Roddick

Shanti Morell-Hart’s contribution to “Then Dig” highlights the sense of excitement that can come from our engagement with instruments, ways of seeing that can catch not only our colleagues’ attention, but generated interest from students and the greater public. Morell-Hart shows that these technologies of enchantment (sensu Gell 1992) are modes of disciplinary and disciplined seeing, relying on particular mediated and trained ways to engage with our materials. She brings us into her piece through the familiar anecdote of the typical conversations we encounter as archaeologists on planes and other public places. I imagine, however, many archaeologists have discussed with their undergraduates how our disciplinary way of seeing can bring into focus a range of multi-scalar phenomena, perhaps the multi-temporality of agricultural landscapes, the systems of garbage disposal within large cities, or the re-daubing of buildings in religious centers. A few of those interested students will follow us to the laboratory, to develop their disciplinary seeing into a form of “disciplined seeing”, whether within Morell-Hart’s paeleoethnobotany lab to identify phytoliths, or perhaps a lithics lab to record bulbs of percussion on pieces of obsidian.

As Morell-Hart demonstrates, technical ways of seeing always introduce issues of representations and translation. I remember several years ago at the Institute of Andean Studies Annual Meetings in Berkeley, the Andeanist Dr. Gary Urton was giving a public talk on the khipu, the knotted string technology used by the Inka. Despite detailed slides and well-explained graphs, a member of the public could not quite follow the way that Urton was seeing these knots. What followed was a difficult interchange between the two. The difficulty came down to the kinds of disciplined seeing that Dr. Urton has spent a career developing from a wide variety of disciplines. In other words, despite his careful lecture, there still remained some presupposition that the audience and the presenter shared a particular way of seeing.

I like Morell-Hart’s use of the concept of “disciplined seeing”, and appreciate her highlighting of Dennis’ interesting article. Dennis clearly shows that for Hooke, the microscope could reveal the power of human art, but it also brought into harsh contrast the difference between products of culture and products of nature. Unlike an archaeologist, Hooke had little time for artifacts: “There are but few Artificial things that are worth observing with a Micro­scope …. For the Productions of art are such rude and mis-shapen things, that when view’d with a Microscope, there is little else observable, but their deformity …. And the most smooth and burnished surfaces appear most rough and unpolisht. (Hooke [1665] 1961: 8; quoted from Dennis 1989: 335). In stark contrast were the divine details seen in natural objects. The argument was that the scientist was a “transparent observer” – here there was no interpretation at the ocular lens. Rather nature revealed the purity of god (I suspect Hooke might spend some time with Morell-Hart’s statement “My god, the things in dirt!”). But it did require a sort of “disciplined seeing”, a standardization of perceptions gained through reason disciplining the experience won through the senses.

As Morell-Hart demonstrates, this notion of disciplined seeing might benefit from further reflection in archaeological science, a set of conversations around not just the microscope, but a range of instrumentations and their mediations within archaeological practice. In taking up Morell-Hart’s provocative riff on Hooke, I’m just as interested in where the scene of disciplined seeing are emerging in new forms of technical archaeological practice. She points to the relatively low tech of smart-phones, and how this democratization might also include the “watering down” of academic imagery (although if the petrography community on social media and Flickr is any indication, I think I’ve seen the opposite!). So let me briefly go to the other end of the spectrum to the high-tech, where the cost and learning curve results in some inevitable gatekeeping, but where we see the emergence of new kinds of “disciplined seeing”.

Working towards a disciplined form of seeing a CT-scan of a ceramic vessel at Sustainable Archaeology at the University of Western Ontario

For the past few months I have been visiting Sustainable Archaeology at the University of Western Ontario for a pilot study of CT-scanning ethnographic and archaeological pottery. There are, in some ways, rather crude objects, things that surely Hooke would disparage. But flying through artifacts at the tiniest of scales is an amazing thing, and this truly is an area where the sensational and the academic merge. For instance, I challenge you not to be amazed at the CT scan of this charred piece of a deciduous hardwood. Or better yet, of a 16th-century Northern European wooden prayer bead, with an interior showing the Last Judgment. Surely even Hooke, who suggested cultural materials had no mysteries within them, would be impressed! But while we can enjoy the voyage through other artifacts, my work requires more than passive enjoyment, and the difficulties of developing a disciplined form of seeing is quite clear with this technology.

I am interested in using micro-CT scanning as a way to probe the traces of skill involved in the production of archaeological ceramics, and we are struggling to figure out a way to compare large datasets. While my interests lie in the images and the interpretations, those working so hard to develop a systematic approach of this amazing technology to archaeological materials (Greene and Hartley 2007; Jansen et al. 2001; Kahl and Ramminger 2012; Sanger et al. 2013) impress me. What standardized protocols can be developed? How must we standardize the software but also our perceptions to create working typologies? What kinds of analytical filters and image analysis program are required to highlight not just Hooke’s divine natural world, but also the complexities of the cultural? Like Morell-Hart, I still need my plane conversation for the greater public (I always go back to either the 2,500 year old red painted skull we found in 2001, or the perfectly preserved 1,500 year old potato), but this emergence of a new way of seeing is also part of the excitement of archaeological science. It is here that we can see the “rules, affordances, expectations, and perspectives” develop, and reflect on our connections and divergences in scientific practice since Robert Hooke’s days. Like the camera or microscope, these are technologies of enchantment that can have powerful effects on our imaginations.

Disciplined Visualization

Colleen Morgan

Last week during one of our Heritage & Play sessions–a series of workshops at the University of York loosely structured around a topic, theory, or making session using play as a productive means to engage with heritage–we tried out an Oculus Rift. After previously trying out Google Glass and Google Cardboard, most of us preferred mixed reality, not a fully (or at least visually) immersive experience. As Morell-Hart describes her immersion in the microscopic world, we were similarly between worlds– while surrounded by a virtual Tuscan villa, we would still be talking to other Heritage & Play participants, still partly present in the classroom.

I’ve found the concept of telepresence to be very useful in describing such situations, or, where you are when you are talking on the phone (Morgan 2009). Not really with the person you are talking to, but not entirely within the place where you happen to be while you are talking on the phone. While we were using the Oculus Rift, participants felt like they were farther away from other people in the room. I find this similar to archaeological investigation, wherein we are not entirely in the present, nor are we entirely in the past. The boundedness of social persons, our subjectivity, is thrown into question through the delegation of perception to technological mediation.

As a digital archaeologist, my primary mode of research is translating disciplined seeing into disciplined visualization. I am challenged by Roddick’s example of the public unintelligibility of the khipu–what kind of intervention could have made Urton’s interpretation obvious? Could we create a 3D reconstruction of the khipu that would be navigable at the microscale, showing the warp of the threads, highlighting the intervals of the knots, annotated by Urton? How can we create data-rich interpretive media that do not fetishize technology but productively use them to show how we see?

Finally, though I consider myself still very oriented toward excavation as my preferred way of archaeological performance, I have spent relatively little time in the field versus behind a computer screen. My “finds” these days are more related to interpretive projects and the links between genetics, bioarchaeology, virtual reconstructions, and avatars. These excite me, but make for hard plane conversations, so I usually revert to the heyday of my time behind a trowel and describe murals and various dead things. So in this I may be failing my own remit–can I create a remediation of my visualization process that will enchant an audience as much as scraping the dirt?

The Beauty and Frustration of Single Moments, Frozen in Time

Our first entry in The Senses and Aesthetics of Archaeological Science comes from Lisa-Marie Shillito, at the University of Edinburgh. Responses follow from co-editors of the issue, Andrew Roddick and Colleen Morgan.

Lisa-Marie Shillito

It wasn’t until I became a micromorphologist that I understood how beautiful even the most unremarkable bit of earth can be, or that I truly understood context. I’ve previously described thin section micromorphology as ‘excavation under the microscope’ – observing deposits, describing their physical characteristics, determining the stratigraphic relationship between components, and reconstructing the processes by which they have formed (Shillito 2013). The sediments themselves become part of material culture. Produced as they are directly by human activity, understanding their mode of formation can aid in the interpretation of the activities that produced them.

The moment where you peer down the lens of the microscope and a picture comes into focus, you may find yourself glimpsing at that elusive ‘frozen moment in time’, a true single depositional event, preserved for prosperity between layers of glass. The moment where you can see the single layer of paint that was applied to a wall and subsequently covered and covered again; you can see the hand of the person that so carefully replastered and painted those walls over and over. The moment where you look at a sequence of floors and see a layer of fine dust less than 1mm thick that accumulated beneath a mat, the everyday dirt that escaped the fastidious sweeping of floors. Beyond buildings we may see the tell-tale undulations and orientations of particles within soft midden sediments that indicate where a person (or creature) once walked, perhaps taking a short cut to a neighbour over the way or making a rest stop to relieve themselves (we see evidence of that too…).

The closer we look, the more we see; the very process of examining archaeological deposits under the microscope gives a new understanding of the past. It is only by examining deposits at the microscale that you can gain a true understanding of ‘single context’ and how the tiny traces from individual activities combine to form cumulative palimpsests (to use the terminology of Bailey 2007) even in cases where we may think we have a ‘single’ context in the field. That moment you realise that ‘in situ’ is a relative concept, and materials we assume are intact have often undergone a series of post-depositional disturbances that have consequences for how they can be interpreted. At one magnification we may be looking at an event that occurred within a single moment; change magnifications and suddenly the temporal resolution shifts.

The implications of Schiffer’s ideas on formation processes are frustratingly obvious at the microscale. How can we really link that date with that artefact, when even in the same layer some small creature has come along and mixed things up a little? And how do we even know this disturbance has happened without using the microarchaeological eye? These processes occur more often than not, yet without microarchaeology, they may go unrecognised. It has been suggested by Smith (1992) that we cannot isolate and analyse instantaneous occurrences in archaeology and even if we could (as is sometimes the case with micromorphology) how do we decide what to analyse? The picture becomes so complicated I wonder if we can ever have a ‘true’ understanding of the archaeological record. Of course the answer is always, ‘it depends’. We can observe deposits at higher and higher resolutions, but the resolution that is necessary depends on specific research objectives.

Unlike specialisms such as zooarchaeology and lithic analysis where you can handle the bones and stones, pointing to features, however subtle, and explain your interpretations, my speciality lies in the unseen, the hidden worlds, the intangible. Explaining is not as straightforward. Explaining the importance of microarchaeological research and being transparent in how you arrived at an interpretation requires the visual. Under the microscope stratigraphy becomes differentiated, the relationships between components within a deposit become apparent and the mechanisms by which materials ended up in their positions can be directly observed in a way that is simply not possible at the macroscale.

Like single context archaeology, one of microarchaeology’s greatest contributions lies in sites with well-preserved stratigraphy and architectural features (Morgan 2010), and its true value can only come from collaboration between specialisms, and considering the sediment as part of the assemblage along with all the other materials we uncover. The sediments can speak their own stories about people in the past, but they also provide important constraints on the myriad of possible interpretations of other artefact and ecofact assemblages, going some way towards reducing their equifinality. It can be disheartening being the specialist whose greatest contribution is in pointing out the taphonomic problems with a favoured interpretation. Luckily, the beauty of the world under the microscope (mostly) makes up for its frustrations.

Tracing the Past under the Microscope

Andrew Roddick

Lisa Marie’s reflections highlight the analytical quandaries, the frustrations, but also the new interpretive and aesthetic worlds that open up through the microscopic gaze. This exploration of the unseen and intangible might be considered as an exploration of the trace, an archaeological element of an entirely different scale than the impressive houses and mounds at Çatalhöyük. Rosemary Joyce (2006: 15) contrasts the trace, which is subtle and contextual, with the monumental, which are those realms of material culture with external hierarchies of value meant to convey sets of meanings over time.  Joyce argues our job is to work at “rematerializ[ing] traces of practices in the past” (Joyce 2012: 121). Such rematerializing requires the specialized tools, learned techniques, and careful theoretical insight and reflection, all essential to our modern disciplinary practice.

As a ceramicist I have been thinking recently about the relationship between my craft of archaeology and those craft producers in the deeper past who produced the vessels I study, and the traces I follow. Just as potters transformed into clay into a vessel through learned technical practice, the pottery is transformed again as it enters my laboratory. I must first decide which traces of the past I’m interested in following, as this choice will determine the next step of the transformation; the sample must be cut either vertically, horizontally or tangentially, each of which will produce distinct traces.  Each step in following these traces also introduces new problems: Are these micro structural traces evidence of clay mixing, or simply bioturbation? These mundane objects introduce monumental issues at the microscale. But like Lisa Marie, these moments are disrupted by aesthetic appreciation, producing a kind of pause similar to that of a sun setting over an important monumental heritage site. Exhibits by archaeological scientists such as David Killick (http://uanews.org/story/art-and-science-converge-state-museum-exhibit) suggests there may be reason to invite a much larger public to peer down the microscope with us, demonstrating the beauty behind even behind the dirt beneath your mat, or the awe in an old clay pot.

The Microarchaeological Eye

Colleen Morgan

What is a context/archaeological unit? How can archaeologists deal with stratigraphic deposits that are too fine to feel, that disappear under the trowel? I find myself alternately defending the craft of archaeological excavation and now, wondering if field archaeologists are actually equipped to excavate at all. Lisa-Marie Shillito’s microlayers: fingerprints, the stroke of a paintbrush, the dust under the mat, a breath, the barest whisper of a deposit, are terrifyingly ephemeral. How soon until we are able to excavate a painting stroke by stroke, unmaking masterpieces in reverse? Recent work in 3D printing fine art paintings by Tim Zaman may make this possible in the near future.

I spent a few days in January in the company of artists at the Van Eyck Institute as part of NEARCH, and after the lectures were done, we compared art practice and archaeology practice. How are we funded? Who is our audience? This process of making our professions intelligible was fascinating, but now I think we might have missed the main point. Archaeologists are un-doers, unravellers of the skein of time, picking out the stitches, ruining the weft. Perhaps that is why some of us refuse to re-knit the past back together again, it is too personal, we are too inexperienced and can only produce a vague, warped parody of the original.

Still, I think about the gestures involved in unpainting a painting. The tiny, precise swipe of the removal of a stipple. The broad slash, peeling off a jagged stroke. What would the Harris Matrix of a Mondrian look like? Squares and lines and red on black? Would the reverse-Pollock matrix be a tangled cloud? How does our arcane, chronologic, geography of a site describe and inscribe the parameters of human action?

One of the artists, Leyla Cárdenas at the Jan Van Eyck Academy specialized in a kind of microstratigraphic excavation. She peeled apart layers of paint, pried apart wallpaper to make an exploded stratigraphy of sites. She is interested in palimpsest, in sections sawed through art. I wonder if there is a microarchaeological movement in art?

CFPo: The Senses and Aesthetics of Archaeological Science

CFPO_Then_Dig

Archaeological science is a critical area of current archaeological practice. Analyses of ancient DNA from the teeth of long-dead ancestors, isotopes found in the remains of broken pottery, and the chemical signatures from flakes of obsidian are radically altering our understanding of the past. Unlike the pervasive fieldwork-based narrative of archaeology, these major discoveries take place far away from the trenches in the clean, well-lit laboratories of major academic institutions. Yet these discoveries are no less impactful, causing in some cases radical shifts in the kinds of stories we tell. Indeed the archaeological scientist is, much like the fieldworker, engaged in the craft of archaeology (sensu Shanks and McGuire 1996).

In this issue of Then Dig we explore encounters with the past in the context of archaeological science. From the abstract expressionist appreciation of ceramic thin sections, to the treasure hunt for phytoliths under a microscope, to the severe precautionary costumes of the Clean Room, we investigate the aesthetic, the multisensorial, and the profound in archaeological science.

Authors might reflect on how the centering of the micro-scale and the abstract are brought to bear, and how the interplay between scientist and materials present the unexpected. We also encourage contributors to consider the embodied moments of lab work and discuss those findings that produce visceral reactions and new understandings of the past.
