This paper examines a neglected fifteenth-century manuscript of the opusculum of Julius Exuperantius. It argues that that manuscript (Bologna, Biblioteca Universitaria, 748) is a sibling of Vatican City, BAV, Vat. lat. 3334, and situates the new manuscript in the stemma established by the last editor. It then proposes a modification to that editor's stemma, arguing that those two fifteenth-century manuscripts in fact descend from Milan, BA, H 37 sup., once owned by Francesco Pizolpasso. Finally, it considers the implications of those arguments for the editing and the history of the text.
