Joseph Salvatore Ackley studies the art and architecture of the medieval West, with a particular focus on metalwork and the medieval church treasury. Additional research interests include figural sculpture, the late medieval altarpiece, medieval theories of matter, and, more broadly, questions of medium, material identity, and what can be loosely termed “the problem of the substrate” – that is, the tension between what we see versus what we know.

Ackley’s current book project, Medieval Gold: Metal and Medium, c. 800-1450, emphasizes the centrality to medieval art of precious metalwork and the metallic aesthetic in general. In addition to the production, use, and occasional liquidation of medieval metalwork, the book addresses how the metal substances themselves were defined, understood, and allegorized by medieval audiences; how the art history of medieval metalwork can be expanded to include issues of material, process, and object morphology; and how and why select traditions of painting and sculpture throughout the Middle Ages purposefully sought to imitate and simulate precious metal. Other forthcoming publications include essays on precious-metal figural sculpture in the Late Middle Ages, the treasury of the Lüneburger Goldene Tafel and its peer monumental winged altarpieces, and Late Carolingian precious metalwork in the orbit of the monk Tuotilo of St. Gall (d. c.913).

Ackley received his Ph.D. from the Institute of Fine Arts at New York University in 2014 and his A.B. from Dartmouth College. He held a Mellon Postdoctoral Fellowship/Lectureship at Columbia from 2014 to 2016. His research has been supported by multiple grants and fellowships, including support from the Deutscher Akademischer Austausch Dienst (DAAD), the Kunstgewerbemuseum – Staatliche Museen zu Berlin, and the N.Y.U. Global Research Initiative. In addition to Barnard and Columbia, Ackley has taught at Colorado College, The Cooper Union, Montclair State University, and N.Y.U.
