January 2014 - Robert Ousterhout, professor of art history and director of the center for ancient studies, University of Pennsylvania. Organized to foster connections between the exhibition Heaven and Earth: Art of Byzantium from Greek Collections at the National Gallery of Art and the research interests and collections of Dumbarton Oaks Research Library and Collection, this colloquium echoes the companion volume to the exhibition catalogue, Cities and Countryside in Byzantine Greece. Held on November 15, 2013, at the Gallery, American and Greek Byzantinists address the many ways community was visualized: in the arts (including mosaics, frescoes, icons, and everyday objects), in architectural construction, and in settings for the ceremonies of daily life and death. Heaven and Earth: Art of Byzantium from Greek Collections is on view through March 2, 2014. This program is coordinated with and supported by Dumbarton Oaks Research Library and Collection.
