The Routledge Research Companion to John Gower reviews the most current scholarship on the late medieval poet and opens doors purposefully to research areas of the future. It is divided into three parts. The first part, "Working theories: medieval and modern," is devoted to the main theoretical aspects that frame Gower's work, ranging from his use of medieval law, rhetoric, theology, and religious attitudes, to approaches incorporating gender and queer studies. The second part, "Things and places: material cultures," examines the cultural locations of the author, not only from geographical and political perspectives, or in scientific and economic context, but also in the transmission of his poetry through the materiality of the text and its reception. "Polyvocality: text and language," the third part, focuses on Gower's trilingualism, his approach to history, and narratological and intertextual aspects of his works. The Routledge Research Companion to John Gower is an essential resource for scholars and students of Gower and of Middle English literature, history, and culture generally.
