What were the medieval stylistic, aesthetic, and literary conventions that Chancer drew upon and knew that his audience would understand? In this rich study Mr. Robertson has included 118 illustrations-of medieval sculpture, cathedral interiors, illuminated manuscripts, paintings, ornamental devices and decorations-to show how these conventions affected the visual arts of Chaucer's time. Special attention is directed to fundamental differences between medieval and modern attitudes toward poetry, and to the significance of these differences for an approach to medieval art. By placing Chaucer fully in his own time, Mr. Robertson establishes new perspectives for understanding Chaucer's poetry. His book is like a rich tapestry weaving together many threads.
