Professor Barber is Acting Director of the Program in Hellenic Studies for Fall 2016. His area of specialization is the history of Byzantine and Post-Byzantine art, with a particular focus on the history and theory of the icon. He has also worked extensively on Byzantine aesthetics and intellectual history and with Byzantine manuscripts. He has written and edited a number of books. These include two studies of the contested status of the icon in Byzantium: Figure and Likeness: On the Limits of Representation in Byzantine Iconoclasm (2002) and Contesting the Logic of Painting: Art and Understanding in Eleventh-Century Byzantium (2007). Current and future research will lead to books that examine the status of the icon in the 14th and 16th centuries.
