Ausonius has become a more accessible writer since the appearance of Professor Green's acclaimed commentary on him in 1991, which among other things stimulated discussion of his text and the textual tradition. This newly revised text takes advantage of recent criticism, both conservative and conjectural, and re-examines the difficulties inherent in the long held view that extant manuscripts derive independently from separate authorial editions. The opportunity has been taken to reassess earlier decisions on various problematic passages and to introduce several new emendations, either in the text or in the apparatus criticus. There is a newly written introduction, in English, the apparatus criticus has been pruned, the concordances expanded, and the bibliography updated. The works in this new Oxford Classical Texts version of the text follow the same order as was established in Professor Green's previous edition of 1991.
