Chrétien de Troyes's reference to Macrobius on the art of description is indicative of the link between the vernacular literary tradition of rewriting and the Latin tradition of imitation. Crucial to this study are writings that bridge the span between elementary school exercises in imitation and the masterpieces of the art in Latin and French. The book follows the development of the medieval art of imitation through Macrobius and commentaries on Horace's Art of Poetry and then applies it to the interpretation of works on the Trojan War, consent in love and marriage, and lyric and vernacular insertions.
