This book argues that John Trevisa’s translations of compendious informational texts disclose an alternative literary history by way of information culture. Bold and lively experiments, these translations were a gamble that the future of literature in England was informational prose. This book argues that Trevisa’s oeuvre reveals an alternative literary history more culturally expansive and more generically diverse than that which we typically construct for his contemporaries, Geoffrey Chaucer and William Langland. Thirteenth- and early fourteenth-century European writers compiled massive reference books which would shape knowledge well into the Renaissance. This study maintains that they had a major impact on English poetry and prose. In fact, what we now recognize to be literary properties emerged in part from translations of medieval compendia with their inventive ways of handling vast quantities of information.
