This volume offers a novel paradigm for explaining late-medieval Anglo-Latin poetry, showing how the verse of the English poet John Gower (ca. 1330-1408), the pre-eminent Latin poet of the Age of Chaucer, developed over the decades from 1370 to 1400. In addition to writing poetry in and translating amongst English, French, and Latin, Gower invented a plain style for Latin public poetry that was emulated by other Anglo-Latin poets. However, at the end of his career he rejected his own Latin-verse invention to take up the late scholastic style at the moment of its decadence.
