In addition to formal classes, Bard Graduate Center runs a series of evening colloquia designed to function in a kind of polyphony with the “for credit” course offerings. Regular evening seminars, which are open to the academic public, serve as foci. In addition, the History and Theory of Museums program brings in speakers affiliated with current exhibitions, and the Medieval, Renaissance, and Early Modern Europe group cosponsors two annual events with the Columbia University interdepartmental group on Medieval and Renaissance studies.
