This comprehensive study deals with the major critical problems of one of the most difficult authors of Latin literature. It examines in a systematic fashion the two major factors which have been assumed to be responsible for the state of the transmitted text of Propertius: dislocation and interpolation. It also covers a large number of notorious cases of verbal corruption and discusses problems of the manuscript tradition on the basis of the most recent research. Beyond questions of textual criticism and history in the narrow sense the book provides also important exegetical remarks on many Propertian passages and deals in a separate chapter with problems of book and poem structure.
