The renewed interest in John Wyclif (d. 1384) has brought this late medieval figure back into the spotlight of historians, giving rise to numerous studies evaluating his thought and its implications in the context of late fourteenth century England. However, it is not possible fully to appreciate Wyclif's importance in late medieval European culture without understanding the legacy of his ideas on the continent. According to the accepted narrative, John Wyclif's thought was mediated to the continent through the scholarly contacts between the universities in Oxford and in Prague, and re-emerged in the Latin writings of Jan Hus. This article argues that John Wyclif's thought, especially his critique of the church's doctrine of transubstantiation, found a larger audience among the rural clerics and laity in Bohemia, whom it reached through Peter Payne, who simplified and disseminated the works of the Oxford master. Wyclif's critique of transubstantiation sparked a nationwide debate about the nature of the Eucharist, generating numerous treatises, both in Latin and in the vernacular, on the subject of Christ's presence in the sacrament of the mass. This debate anticipated, a full century earlier, the famous debate between Luther and Zwingli and the Eucharistic debates of the sixteenth century Reformation more generally. The proliferation of vernacular Eucharistic tractates in Bohemia shows that Wyclif's critique of transubstantiation could be answered in a number of different ways that included both real presence (however defined) and figurative theologies—a fact, which, in turn, explains the doctrinal diversity among the Lollards in England.
