Wolfram von Eschenbach's Parzival is the most widespread medieval German courtly romance. Despite this, work on the history of the text and transmission of this important work has been sadly neglected. The present monograph attempts to determine the status of the transmission branch *T taking account of the present methodological discussion about the concept of 'version'. In addition, it provides comprehensive textual analyses giving insights into the substantive qualities of this version, which has hardly been considered in research.
