Robyn Barrow is an art historian of medieval Europe in a connected world. She specializes in art, cultural exchange and environmental histories of Scandinavia and the North Atlantic. Her region of study encounters the sovereign homelands of the Inuit and Sámi, and she has traveled extensively in the Arctic. Her manuscript, Tracking North: Art, Ecology and Exchange in the Medieval Nordic World explores cultural systems extending across the vast spaces of the north. The project illuminates the ways that systems of secular and religious power were creatively negotiated by communities across the wide Norse-settled region in the Middle Ages, from Gotland to Greenland. Her second project considers the relationship between medieval art and the temporalities of contemporary environmental crisis.

Her research has been supported by major institutions including the Center for Advanced Study in the Visual Arts; a collaborative initiative between the Fulbright Foundation and National Science Foundation for Arctic Research; and the Swedish Institute. Her published work has appeared in major journals such as The Medieval Globe and Different Visions.

Sarah M. Guérin is Associate Professor of Medieval Art in the History of Art Department at the University of Pennsylvania. Her research centres on materials and materiality, with an accent on the socio-economic structures which inflect production and use, as well as the symbolic and affective potential of materials. Her first monograph, French Gothic Ivories: Material Theologies and the Sculptor’s Craft (2022), was awarded the John Nicholas Brown prize from the Medieval Academy of America. Her many publications on the medieval ivory trade link West African economics with those of the Mediterranean world. This expertise led to her inclusion on the steering committee for the award-winning exhibition Caravans of Gold, Fragments in Time: Art, Culture and Exchange across Medieval Saharan Africa (2019). Guérin’s longstanding interest in trans-Saharan trade, where economics is deeply inflected by the environment, similarly informs her current book project Goldrush 1270: Paris, Florence, Tunis, Ni-Jimi.
