The thesis comprises a text of the Querolus based on all the extant manuscripts, with an apparatus criticus and translation. The text is preceded by an introduction, and followed by a textual, linguistic, stylistic and literary commentary, a bibliography, and an index uerborum. The introduction considers: the history and interrelations of the manuscripts; previous editions and translations; author and dedicatee; place and date of composition; references to contemporary history and thought; genre, characters and plot; sources and Nachleben; and rhythmic structure. An edition and commentary of the Lex Conuiualis, which occurs in all the complete manuscripts of the Querolus, is also provided.
