Multispectral Imaging of Leonardo da Vinci Drawings

By Cerys R Jones, on 16 June 2019

In the first year of my PhD, I was asked by Alan Donnithorne, the former head of conservation of prints for the Royal Collection Trust, whether I would be interested in capturing multispectral images of three Leonardo drawings for a book he was writing. Of course I eagerly agreed and in July 2016 Alan brought three beautiful studies by Leonardo to UCL ready for imaging.

The first drawing was the ‘Studies of horses and horses’ heads’ created circa 1481. This is a metalpoint drawing of the portrait of a horse’s head and another in side-profile. To create a metalpoint drawing, a metal-nibbed stylus is used to engrave lines onto paper that has been prepped with glue and ground animal bone, whilst also leaving a deposit of the metal. Although only two horses heads could be seen in visible light, when illuminated in ultraviolet light, two more horses and a dog appeared at the bottom of the page that were invisible to the human eye.

The second drawing was of ‘the anatomy of a bear’s foot’, circa 1488-90. Leonardo initially studied anatomy to inform his paintings;however,this eventually evolved into a plan to write a never-completed treatise on the subject. Martin Clayton, in his 2019 book Leonardo da Vinci: a life in drawing, explained how, at the time, human dissection was illegal and so Leonardo may have been interested in the bear’s foot due to the similarity in the way humans and bears walk. The multispectral imaging of this drawing enabled the different materials (metalpoint, pen and ink, and white heightening) to be separated and show how Leonardo built up his compositions.

The final drawing was a study for ‘the drapery of the Madonna’s arm’ (c. 1510-1515) created for ‘the Madonna and Child with St Anne and a lamb’, a painting currently in the Louvre Museum in Paris. The multispectral imaging revealed the outline of the arm under the drapery,implying that Leonardo first drew a template for the arm and then built the drapery on top of that . The images also enhanced the different materials, including black and red chalk, pen and ink, brush and ink, and white opaque watercolour.

The full results from this imaging are in Alan’s book Leonardo da Vinci: A Closer Look. This fascinating book investigates many of the Leonardo da Vinci drawings held in the collection at Windsor Library, using a variety of imaging techniques, including multispectral imaging, microscopy, X-Ray fluorescence, and more. He shows Leonardo’s drawings in a way never seen before—including these features invisible to the human eye—to present a detailed view of Leonardo’s musings and thoughtful mind.

The studies for ‘the anatomy of the bear foot’ and ‘the drapery of the Madonna’s arm’ are currently on display in the Queen’s gallery as part of the new exhibition Leonardo da Vinci: a life in drawing to commemorate the 500-year anniversary of Leonardo’s death. This exhibition displays over 200 drawings from Leonardo’s life, spanning a range of topics including anatomy, optics, engineering, botany, cartography and more. I was honoured to be invited to a private view of the exhibition before it was open to the public to celebrate Leonardo’s work and the release of the book. The exhibition is captivating and provides a fascinating insight into Leonardo’s mind, which you can see jumping across subjects on a single piece of paper. I encourage everyone to attend and be inspired by Leonardo’s inquisitive and ingenious mind.

“When gibbons sing, I know it will rain”

By Carolyn Thompson, on 13 May 2019

I started writing this blog post whilst sat in a half-deserted village high up in the Gaoligong mountains in China. Occupied by only 10 remaining elders who refused to leave their traditional lives behind, I had the privilege of staying here and immersing myself into daily life.

I am seated by myself as the morning sun blinds me as it peeps out from over the moss-covered tiled roofs. Two chickens are currently sneaking past me into the kitchen to morbidly watch their duck cousin be prepared for breakfast. They scream as my host shoos them away flapping her arms wildly.

The houses date back 50+ years and are made from old wood and bamboo harvested from the forest in the days before the nearby reserve was established. Mules are found on the ground floor of these dwellings with humans roosting above. As a result, night-time can be a very noisy affair!

I also experienced a huge storm at 3 am. I’ve slept through many tropical storms when I lived and worked in Indonesian Borneo, but this was something else. The walls rattled as the rain beat against it and droplets started to seep through and trickle down. I thought the storm would snatch the flimsy roof right off, but I am glad to report that all houses — and mules — were still standing when I woke up.

My PhD is all about understanding local nature and wildlife values, comparing gibbon (small ape) knowledge, and investigating patterns of natural resource use. I have spent the past few months collecting social data in the form of structured interviews and small group discussions with local communities in both Hainan and Yunnan provinces. To get the most candid answers, it is important to immerse yourself into local life.

I have drunk countless cups of green tea and bottles of “bai jiu” (lethal Chinese wine) as a result, been dressed up as a local Hei Lisu person, braved eating the 100-year old egg, and scoffed so many sunflower seeds that I am ready to sprout!

Before embarking on my PhD journey, I was given an antique book by Robert Van Gulik, a Dutchman fascinated by gibbons and their significance in Chinese culture. Published in 1967, “The Gibbon in China” is a magical collection of poems, stories and paintings dating back to 200 BC. Rich in its content, I was overwhelmed with the stories about “lonely”, “sad-looking” yet “magical” apes who sing haunting and melancholy songs in the Chinese mountains.

Taoists (those that believe in ancient nature-worship regarding the flow of “ch’i” energy in all living things) talked about gibbons being superior to humans. Gibbons were often referred to as “gentlemen” as discussed in my previous blog. Everyone loves good manners — bring a gibbon to meet the parents and they won’t be disappointed due to their impeccable “table manners” (unlike their mischievous macaque monkey cousins), according to an 8th-Century poet, Liu Tsung-Yuan. Their intelligence, supposedly similar to humans, is also regularly mentioned, especially when needing to drink water from a nearby river. Forming a chain by holding hands, gibbons would lower themselves down to the river. One should therefore never “…place a gibbon (Yuan-yu) in a barred cage [as] how could he then show his clever skills?” (4th Century statesman, Ch’u-tz’u).

Forming a “Gibbon Chain”. Nineteenth Century. Sourced from Van Gulik’s 1967 essay on “Gibbons in China”.

Having read this book from cover to cover, I was pumped to record rich gibbon stories during my field season. I was therefore incredibly shocked and disappointed to learn that many traditional stories have not been passed down through the generations.

China is made up of 56 different ethnic groups, all of which used to be rich in culture and history with traditional dress and sigils (both of which are now rarely seen). I interviewed participants from six of these ethnic groups and asked them questions regarding  the importance of gibbons and forests in their local culture. Participants either didn’t understand the question or they would say there is no connection.

I was relieved to hear that a few elders still have a tale or two to tell, especially when it comes to gibbons being able to predict the weather:

“When gibbons sing, I know it will rain tomorrow.” (Anonymous).

An elder in Hainan province told me about how gibbons came to be which involved a naughty, lazy boy who was scolded with an iron on his butt. He then sprouted hair and turned into a gibbon.

I also had a surprisingly funny interview with a 70-something year old man who used to work in Burma harvesting wood to sell back to the Chinese. He spoke about his love of gibbons…to eat! We spent most of our interview crying with laughter as his opinion was so far from my own. He kept insisting that gibbons were incredibly ugly and thought I was crazy because I felt they had aesthetic value.

“Look at their ugly faces!” He would yell. “Ah, they taste so good! Such a shame the government won’t let me hunt them anymore.”

It is important when I conduct these interviews that I remain impartial. At the end of the day, my PhD is all about finding sustainable solutions for both humans and gibbons alike.

My favourite moment was with an 87-year old woman who heard that a “laowai” (foreigner) was staying in the village. Having never left her village or seen a Caucasian woman before, we had a very special, informal moment bonding over gibbons and discussing what life was like during her youth — and what life was like now.

Although I am still at the start of my PhD journey, I have teamed up with a local non-governmental organisation called Cloud Mountain, who carry out conservation education activities. We hope to work together to reintroduce some of these traditional gibbon stories back into these villages. With only 28 Hainan gibbons, 150 Skywalker Hoolock gibbons and 110 Cao Vit gibbons remaining (my three study species), hopefully we can remind people of their magical, shared history and raise the profile of these forgotten apes before it is too late.

The Imperial Gentleman of China

By Carolyn Thompson, on 3 July 2018

I am a primatologist; that is, a scientist who studies the behaviour, abundance and conservation status of monkeys, lemurs and apes. My specialty area and the focus of my PhD research here at University College London, is the plight of the gibbons, the smallest of the apes.

Gibbons are often forgotten in the shadow of their great cousins — the orangutans, chimpanzees, bonobos and gorillas — receiving less funding, as well as research and media attention. This is very unfortunate seeing as 19 of the 20 species are on the brink of extinction. The Hainan gibbon, for example, is the world’s rarest primate with a mere 26 individuals making up their entire global population.

I am always thrilled therefore to see media articles raising some much needed gibbon awareness, even if the news story doesn’t always paint us humans in the best light.

In 2004, one of my supervisors from the Zoological Society of London, stumbled across a gibbon skull inside a tomb in Xi’an, Shaanxi Province, China. The skull is believed to be ca. 2,200-2,300 years old and the potential property of Lady Xia, the grandmother of China’s first emperor, Qin Shihuang, who is famous for his striking terracotta army. Inside this ancient tomb was a whole menagerie of other animal skeletons including a crane, bear and a leopard — yet another example of human-animal relationships that have dated back millennia.

Although this exciting discovery could tell us a lot about our evolutionary shared ancestry with gibbon species, there are still many unanswered questions. We are unsure if the skull, now said to belong to Junzi imperalis (meaning the ‘imperial man of virtue’ due to the strong historical relationship between humans and gibbons in Chinese culture) is in fact a new species and where it came from. There are strong indicators, however, suggesting that this potentially new species of gibbon could be the first ape to have vanished off the face of the earth due to human pressures. Now extinct, we need to look at our current impact on the planet to ensure we don’t do the same with our other cousins.

Part of my PhD research examines the relationship between humans and animals, especially amongst local communities found in gibbon habitat regions. This intrigue, along with my love of mingling with the public, led me to my new role as a Student Engager in the UCL museums. For example, the Ancient Egyptians also had a strong connection with animals which I hope to explore over the coming months in the UCL Petrie Museum, and the Grant Museum of Zoology also has a couple of gibbon skeletons hanging around. Come and see for yourself!

Adventures in Eighteenth-century Papermaking

By Hannah L Wills, on 21 July 2017

By Hannah Wills

 

 

Earlier this summer, I gave a talk with some of the other engagers at our ‘Materials & Objects’ event at the UCL Art Museum. In preparing for the event, we were all challenged to think about the objects, materials, and physical ‘stuff’ that we work with on a daily basis. As I’ve written about before, my research focuses on the notebooks and diaries of a late eighteenth-century physician and natural philosopher, Charles Blagden (1748-1820), who served as secretary to the Royal Society. One of the things I’m interested in is how Blagden used his notebooks and diaries to keep track of his day-to-day activities, as well as the business of one of London’s major learned societies. Record keeping and note taking was a central part of Blagden’s life, and it’s owing to his impressive record keeping habit that there’s one material I handle in my research more than any other: eighteenth-century paper.

When I began preparing my talk for ‘Materials & Objects’, I started to think about how I might bring paper, a relatively mundane material, to life. My initial reading on the craft of papermaking told me that despite it being a 2000-year old process, making paper by hand has changed relatively little between then and now.[i] Out of curiosity, I decided to do an experiment, and to see if I could replicate some of the processes of eighteenth-century papermaking at home, in my kitchen.

The first stage in the papermaking process is to select the material from which the paper is going to be made. In the eighteenth century, this would typically have been cotton and linen rags. Towards the end of the century, shortages of rags, in part caused by an increased use of paper for printing, meant that makers began to experiment with other materials. In 1801, the very first book printed on recycled paper was published in London—that is, paper that had been printed on once before already.[ii]

Having selected the material, the next step is to break it down, making it into a pulp. When papermaking was first introduced in Europe in the twelfth century, rags were wetted, pressed into balls, and then left to ferment. After this, the rags were macerated in large water-powered stamping mills.[iii] In the eighteenth century, a beating engine, or a Hollander, was used to tear up the material, creating a wet pulp by circulating rags around a large tub with a cylinder fitted with cutting bars (see below).[iv] For my purposes, I found a kitchen blender worked well to break up scraps of used paper from my recycling bin at home, ready to make into new blank sheets.

Having been broken down, the liquid pulp mixture is then transferred to a container. In the eighteenth century, someone known as the ‘vatman’ would have stood over this container and dipped a mould into the solution at a near-perpendicular angle. Turning the mould face upwards in the solution before lifting it out horizontally, the vatman would have pulled out the mould to find an even covering of macerated fibres assembled across its surface. It is these fibres that would later form the finished sheet of paper.[v]

The moulds used in papermaking determine several features of the finished sheets of paper, including shape, texture and appearance. The type of mould first used in European papermaking was known as a ‘laid’ mould. This mould typically featured wires laced horizontally into vertical wooden ribs, meaning that when the mould was pulled out of the vat, the pulp would lie heavier on either size of the wooden ribs, giving vertical dark patches and the characteristic markings of ‘laid’ paper.[vi]

In mid-eighteenth century Britain, a new type of mould became widely used, developed by the Whatman papermakers based in Kent. This mould was known as a ‘wove’ mould, and had a much smoother surface, consisting of a fine brass screening that was woven like cloth. These moulds imparted a more uniform and fabric-like texture to individual sheets.[vii]

Between the watermarks the smooth surface of the woven screening is visible, which leaves the paper with a fabric-like textured appearance, without the prominent horizontal and vertical lines of laid paper.

For my own papermaking, I chose to dip a piece of fine sieve-like material into my makeshift vat, aiming to replicate partially the texture and appearance of a ‘wove’ mould. The implement I chose for this was a small kitchen pan splatter guard, made up of fine mesh that when pulled out of the vat would hold a layer of fibres on its surface.

After the mould was pulled from the vat, the eighteenth-century vatman would pass it on to a coucher who would remove the sheet from the mould, before pressing it between felts to remove the water.[viii]

In order to remove my sheet of paper from the mould, I placed another sieve-material implement over the top of the fibres and pressed down with a sponge. With a tea towel placed underneath, this worked to remove much of the water without the need for a proper press. Pulling the top piece of sieve away from the bottom, I was left with a drier surface of fibres, which could be carefully lifted off the mould, and set aside to dry.

At this point in the eighteenth-century process, sheets were ‘sized’—dipped into a gelatinous substance made from animal hides that made the sheet stronger and water resistant.[ix] After my sheets had been left to one side to dry for a few hours, I decided to experiment by writing on them. I had not applied size to any of my sheets, so found that when I wrote on them the ink spread out, giving a sort of blotting paper effect.

(Left) After pressing, the sheets are dipped into large tub containing size. This step is important if the paper is to have a slightly waterproof quality that enables it to be written on without the ink spreading.

After having size applied, sheets in an eighteenth-century papermill would have undergone a number of finishing stages. These included polishing and surfacing, processes that gave the paper a more uniform appearance.[x] With my own sheets of paper, I found passing a warm iron over the surface achieved a similar effect, removing some of the creases and wrinkles that had appeared during drying.

It is after these final finishing and drying processes that sheets of paper are ready to be packaged up and sent to the stationer’s.

Replicating historic crafts and processes is not new within the discipline of history. One of my favourite examples is a paper that was published in 1995, in which the historian Heinz Otto Sibum recreated the experiments of the scientist James Prescott Joule (1818-1889) in determining the mechanical equivalent of heat. By trying to recreate the experiment from Joule’s notes, Sibum revealed that Joule made frequent use of the bodily skills he developed while working in the brewing industry, such as the ability to measure temperatures remarkably accurately by using only his elbow.[xi] Often, attempting to replicate an experiment or craft will reveal just how much it relies upon implicit bodily skills, or tacit knowledge, the kinds of ‘knacks’ that are not written down but are simply known to those who perform an activity regularly.

In attempting to replicate the craft of eighteenth-century papermaking, I really only approximated the process, making substitutions for equipment and improvising a number of techniques, particularly when it came to removing my delicate wet sheets of paper from the mould. I think the biggest lesson I learnt was to have a greater appreciation of the material, and just how many skills and processes went into crafting each sheet of paper in the eighteenth century. Characteristics of individual sheets such as colour, texture and markings had not caught my attention in the archives previously, but I now find them fascinating for what they can reveal about the nature of the fibres used, the construction of the paper mould, and the processes followed by each individual papermaker.

Five years of research: a summary

By Stacy Hackner, on 3 July 2017

DSC_0745

by Stacy Hackner

A PhD often feels like an unrewarding process. There are setbacks, data failures, non-significant results, and a general lack of the small successes that (I hear) make general worklife pleasant: “I got that promotion!” “Everyone applauded my presentation!” “I moved to the desk near the window!” PhD life is one giant slog until the end, a nerve-wracking hours-long session where you’re grilled by the only people who know more about your field than you.

I survived.

Hopefully some of you have been following my research here, starting from astronauts and moving on to runners and foraging patterns. It all ties together, I promise. I recently gave a talk at the Engagers’ event “Materials & Objects” summarizing my research, which I can now tell you about in its full glory! I’m pleased to announce: I had significant findings.

The lowdown is that (as expected) there are differences in the shape of the tibia (shin bone) between nomads and farmers in Sudan. Why would this be? Well, if you’ve been following along, bones change shape in response to activity, particularly activities performed during adolescence. The major categories of tibial shape were those that indicated long-distance walking, doing activity in one place, and doing very little activity. Looking at the distribution, the majority of the nomadic males had the leg shape indicating long-distance walking, and some of the agricultural males had the long-distance shape and others had the staying-in-place shape. This makes sense considering the varying types of activity performed in an agricultural society, particularly one that also had herds to take care of: some individuals would be taking the herds up and down along the Nile to find grazing land while others stayed local, tending farms. While it’s unclear how often a nomadic group needs to move camp to be considered truly nomadic, in this case it seems like they were walking a lot – enough to compare their tibial shape to that of modern long-distance runners. These differences in food acquisition are culturally-adapted responses to differing environments: the nomads live in semi-arid grassland and can travel slowly over a large area to graze sheep and cattle, while the farmers are constrained to a narrow strip of fertile land along the Nile banks, limiting how many people can move around, and how often.

Perhaps the most important finding is the difference between males and females. In addition to looking at shape, I also conducted tests to show how strong each bone is regardless of shape, a result called polar second moment of inertia (and shortened to, unexpectedly, J). The males at each site had higher values for J – thus, stronger bones – than the females. However, the nomadic females had higher J values than some of the males at the agricultural sites! This is in spite of most females from both sites having the tibial shape indicating “not very much activity”. This shape may be the juvenile shape of the tibia, which females have retained into adulthood despite performing enough activity to give them higher strength values than male farmers. Similar results have actually been noted in studies examining different time periods – for instance, the Paleolithic to Neolithic – and found much more similarity between females than between males. Researchers often interpret this as evidence of changing male roles but female roles remaining the same, which strikes me as unlikely considering the time spans covered. I instead conclude that females build bone differently in adolescence, and perhaps there are subtleties in bone development that don’t reveal themselves as differences in shape. As females have lower rates of testosterone, which builds bone as well as muscle, they may have to work harder or longer than males to attain the same bone shape and strength. I’m using this to argue that the roles of women in archaeological societies – particularly nomadic ones – have been unexamined in light of biological evidence.

Of course, the best conclusion for a PhD is a call for more research, and mine is that we need to examine male and female adolescent athletes together to see when exactly shape change occurs. If we can pin down the amount of activity necessary for women to have bones as strong as those of their male peers, we can more accurately interpret the types of activities ancient people were performing without devaluing the work of women.

My examiners found all this enthralling, and I’m pleased to say I passed! The work of this woman is valued in the eyes of the academe.

Materials & Objects: What do researchers at UCL study?

By Hannah L Wills, on 2 May 2017

Materials & Objects, an afternoon of short talks by UCL’s student engagers, will be taking place on Thursday 18 May 2017, UCL Art Museum, 2-4pm.

Taking a look at the range of posts we’ve had on our blog just recently, I’m struck by how many different kinds of materials we work with as researchers at UCL. From brains to archives, from skeletons to manuscripts, there’s a whole range of ‘stuff’ that forms the core of our research as PhD students, not to mention the objects we engage and interact with while we work in the museums, chatting about our research with the public.

In two weeks, a group of student engagers are getting together for an afternoon of short talks in the Art Museum, presenting and explaining their research based around the theme of materials and objects. Each short talk will give an insight into some of the research that happens at UCL, in departments ranging from Security and Crime Science to the Institute of Archaeology.

Arendse Lund, whose blog posts have explored unusual book-bindings as well as medieval twitter, will be ‘Marvelling at Medieval Manuscripts’ and their makeup.

Speaking about my work on eighteenth-century notebooks and diaries, I’ll be explaining how eighteenth-century paper was made, and how it was used by note-takers.

Kyle Lee-Crossett, who reflected last month on the absence of people in images of archives, will be delving into ‘Invisible Boxes’, exploring the materials of archives and collections.

Legacy in Conversation: Scrapbooks, Albums and Diaries in the 18th century

Hannah’s lunch hour talk, ‘Legacy in Conversation: Scrapbooks, Albums and Diaries in the 18th century’, will take place on Tuesday 14 March, 1-2pm, in the UCL Art Museum

 

 
How did people organise their notes and thoughts in the eighteenth century? This question is something that my research aims to get to grips with as I explore the diary and manuscript notebooks of Charles Blagden (1748-1820), an eighteenth-century natural philosopher, and secretary to the major scientific institution, the Royal Society. Whilst working on this strand of my research, which focuses on early modern information storage, retrieval and management, I’ve come across several synergies with the Art Museum’s current exhibition, entitled Legacy: Richard Cooper Jnr and the Artist’s Album.

Legacy presents, for the first time, a number of albums produced by Richard Cooper Jnr, a little known eighteenth-century artist and innovative printmaker. As this exhibition shows, Cooper used his albums as repositories for sketches of artworks produced by other artists, as well as his own ideas and compositions. This use of the artist’s album closely mirrors another form of notebook popular in the eighteenth century, known as the ‘commonplace book’. These notebooks, whose origins can be traced back to the Renaissance, served as a kind of textual scrapbook, as a repository for favourite passages copied from other texts, as well as a note-taker’s own thoughts and anecdotes. Such notebooks enabled individuals to retrieve information, and were often used to help the note-taker pen their own prose compositions, including poems and essays.[i]

Next week, I’ll be giving a lunch hour talk at the Art Museum, exploring some of the connections between the albums of Richard Cooper Jnr and the diaries and commonplace book of Charles Blagden. Described as ‘visual diaries’, I’ll explore how Cooper’s albums are similar to Blagden’s own diary, as devices for storing important ideas, memories and information. Exploring both the text and images found within Blagden’s commonplace book, I’ll take at look at how these notebooks functioned as a kind of textual analogue to the artist’s album, and how albums, diaries and notebooks contribute to notions of ‘legacy’.

Engaging Conversations: What do a shift in the Grant Museum and the diaries of Charles Blagden have in common?

By Kevin Guyan, on 28 June 2016

By Hannah Wills

 

 

I’m thrilled to have recently joined the team of student engagers at UCL, and to have had my very first shift in the Grant Museum this month. As a historian of science, working on Charles Blagden (1748-1820), Royal Society secretary to the famous naturalist and patron of science Joseph Banks, I instantly found connections between the museum’s natural history specimens and my own subject interests. However, during my very first shift, I discovered another more personal link between my own PhD research and my experiences as a student engager.

My work on Charles Blagden involves reading and transcribing some of his extensive diary, which he kept for most of his life, now looked after in the archives of the Royal Society. In his diary, Blagden recorded a daily inventory of his activities: where he went, whom he saw, and whom he dined with (Blagden was never one to miss out on a gastronomic get-together!).

Within this inventory-style diary are often records of the actual conversations had around the breakfast, lunch or dinner table. A friend of naturalists, botanists and all manner of scientific fellows of the Royal Society, Blagden frequently had conversations about exotic looking artefacts from fascinating and far away places, collected during the latest voyages of exploration. What’s more, many of these conversations took place with the objects of discussion right before the eyes of the company. During my first shift as a student engager, it struck me how chatting to visitors about strange and exotic creatures—ones which we had right before our eyes—seemed to echo what Blagden got up to on a nearly daily basis, over 200 years ago.

Something I’ve particularly noticed in Blagden’s dinner-table conversations is the use of comparison, and a fascination with the exotic. When in conversation about animal husbandry in China, Blagden was thrilled to learn how buffaloes, instead of horses, were used to plough fields—a very strange sight indeed! When talking about different species of nut, collected by naturalists on various voyages, Blagden and his friends compared them in size, shape and even taste, to those they had seen before, allowing them to make sense of new and exciting flora and fauna in relation to those they already understood.

Chatting to visitors in front of exotic looking specimens in the Grant Museum, I noticed just how often we made use of comparisons between a strange looking skeleton and something we both knew well. Sometimes this comparison was suggested by the name of the creature. Standing in front of the cookiecutter shark jaw with one visitor, we both shuddered with a kind of macabre delight at how this animal uses its cookie-cutter like teeth to cut round lumps of flesh out of its victims, just as a real cookie-cutter is used to cut shapes out of a piece of dough.

There is definitely a thrill to seeing something new and exotic, something from far away, or something more mundane that you’ve simply never noticed before. As a student engager, I’m really looking forward to my next shifts in the Grant, Petrie and Art museums—not least for the opportunities I’ll get to see and learn about something completely new, and to chat about it with visitors, just as Blagden and his friends discussed the latest curiosities that made their way to London in the late eighteenth century.

 

National Gallery of Ireland Research Day

By Kevin Guyan, on 9 March 2015

The Student Engagement project was the subject of a paper presented to an audience of museum and gallery professionals, researchers and members of the public at the National Gallery of Ireland Research Day on 6 March 2015.

The day’s theme was Conditions of Display: Research & Practice and preceded the reopening of the gallery in 2016, in which curators will make a number of decisions on rehanging and reimagining the collection.  It was therefore an ideal opportunity to share the ongoing link between researchers and public engagement taking place across UCL Museums and the possibilities the Student Engagement project presents for museums and galleries in both the UK and Ireland.

Artists and researchers from a number of UK and Irish universities and art colleges shared their experiences of devising, organising and interpreting exhibitions, as well as the public’s experience of these exhibitions once they go ‘live’.

Sean Rainbird, Director of the NGI, opened the day noting the need to consider the ‘physical experience of humans in space’ when thinking about museums and galleries.  Adding that this not only included the arrangement of space and objects but also the management of sound.

Gemma Tipton, known for her commentary on art, architecture and aspects of Irish culture for The Irish Times and regular contributions to TV and radio, raised interesting points about what the exterior of galleries say about the content within.  This instantly conjured up the very different entrances to the Grant Museum and Petrie Museum, and whether this shapes people’s interpretations of museum objects prior to their arrival in the museum.

Paul Green, PhD Candidate in the School of Art and Media at the University of Plymouth, shared the ongoing work of Cork’s South Presentation Heritage and the conversion of a convent into a public heritage site.  The need to ‘future proof’ the site so that it is ready for unforeseen uses and forms of engagements was insightful, as well as the involvement of design students in devising ways for the public to interact with the objects and space.

Mirjami Schuppert, PhD Candidate at Ulster University, examined the role of the curator in mediating artistic interventions.  She drew a distinction between ‘conventional curating’ and ‘contemporary curating’, which revolves around ‘creative authorship and discursive coproduction’, and expressed the need for those working with archives to give something back in return.

Saidhbhín Gibson, Masters in Fine Art-Sculpture Candidate at the National College of Art and Design, shared her artistic interventions in permanent collections at The Natural History Museum and The Lab, Dublin.  She also raised questions over the level of interpretation presented in museums, and the exciting possibilities that emerge when visitors are not given directions on how they should or should not understand an object on display.

Sabina MacMahon, Masters in Museum Studies Candidate at the University of Leicester, discussed her creation of the fictitious South Down Society of Modern Art and exhibition of its work.

Kevin Guyan concluded the day’s papers by sharing the case study of the Student Engagement project and how two-way discussions with visitors helped promote his work as well as reconsider views towards his own research.  He argued that curators should build strategies for engagement, like the Student Engagement project, into the planning of exhibitions and hanging of collections from the offset, as it brings a number of benefits for researchers and the public.

Conditions of Display

The Research Day discussed new ways to share collections.

A panel discussion followed that examined a number of these themes in further depth.  One person questioned the expandability of the Student Engagement project to larger, non-university spaces.  Though the focus of the project has thus far been UCL’s three campus museums, it seems likely that elements of this project could transfer to differently sized museums not linked to universities.  Another person asked whether this style of engagement was dependent on the layout of the museum space?  As Student Engagers report differing levels of success in different parts of UCL museums, environment undoubtedly plays a role in people’s willingness to converse.

People clustered afterwards to share their thoughts, both positive and negative, on the Student Engagement project.  A few audience members found the idea of a researcher approaching them when contemplating a painting or museum object an unwelcome idea, though admitted that others may enjoy this opportunity to share their opinion on the collection.  Others identified the two-way benefits of bringing researchers into the museum or gallery space and were excited by the project’s potential to serve as a training platform for students.  Expanding the skillset of PhD students, while also bringing into museums and galleries new methods of public engagement, interested many of those in attendance and it is hoped that elements of the work taking place at UCL appears in other museums and galleries.
