In this book, Katie Reid argues that the fifth-century author Martianus Capella was a significant influence in the late Middle Ages and Renaissance. His poetic encyclopaedia, The Marriage of Philology and Mercury, was a source for writing on the liberal arts, allegory and classical mythology from 1300 to 1650. In fact, writers of this period had much more in common with Martianus Capella than they did with older ancients like Homer and Virgil. As such, we must reshape our understanding of late medieval and Renaissance encounters with the classical world by exploring their roots in Late Antiquity.
