This study deals with Latin texts from the twelfth to the fifteenth century that discuss the emendation of the Latin Bible. After consideration of the medieval terminology for different versions of the Bible, it offers an overview of the transmission of the Latin Bible in the Middle Ages and its medieval editions. A survey of the cult of Jerome precedes an investigation of statements by textual critics about the status of the Vulgate and other versions of the Bible. The main body of the work is dedicated to the authors' views of the textual tradition by examining their statements on the status of Hebrew, Greek and Latin manuscripts for the emendation of the Latin Bible. Finally, this study explores the struggle between consuetudo and veritas and the role of grammar in the emendation of the Latin Bible.
