William Turner remains an understudied figure of Reformation scholarship. He was a dedicated doctor, scientist, and Lutheran reformer. This thesis examines Turner and his place in the history of ideas. It looks closely at his three editions of A Comparison Betweene the Olde Learnynge and the Newe (1537, 1538, 1548) and explores how these texts fit into the history of ideas and reflect the larger religious debate occurring in England in the 16th century. It also explores Turner's connection to the German reformer Urbanus Rhegius. I argue the connection between these two men and their writings function as a microcosm of the Reformation. / Master of Arts
