 The strengths of the museum's holdings within this broad spectrum often reflect the Department of Art and Archaeology's curriculum, though with many unexpected treasures, due to the interests of donors.The collection of medieval art is primarily the result of museum purchases, demonstrating the techniques and materials of artists, as well as the secular and spiritual uses of their work.Among the collection of stained glass is a window from Chartres Cathedral, and the collection of medieval sculpture includes a "gisant" of a Spanish knight.
