Allison Stielau is Lecturer in the History of Early Modern Art at University College London. Her focus of study is object cultures in Northern Europe, c. 1400–1700. She received her PhD from Yale University and was then a Postdoctoral Fellow with the Early Modern Conversions Project at McGill. She holds a bachelor’s degree in English from Yale and a master’s degree in the History of Decorative Arts and Material Culture from the Bard Graduate Center and was a fellow at the Getty Research Institute in 2014–2015. Allison has published articles on leather étuis, fifteenth-century engravings of metalwork, and, most recently, on weight as a category of historical and art historical evidence. Her current work concerns metallic transformation, from the representation of Ovidian metamorphosis on seventeenth-century silver vessels, to the conversion of coins into printed illustrations.
