An edition of the Commentariolum appeared in the Loeb series (Cicero XXVIII) in 1972 with translation, notes, and introduction by M. I. Henderson, who died before completing it. Her work was revised by E. H. Warmington, then Editor of the series, who added a text and critical notes along with the supplementary matter at the end of the Introduction.
I have kept most of this valuable legacy. But the text, with three changes, is that of my Teubner edition of 1998, and the critical notes are in line with the others in this volume. A few changes have been made in Henderson’s translation. Some of her notes have been retained, others replaced, and further notes have been added. And the index is new.
To the bibliography Warmington gives in his addendum to the Introduction should now be added: D. Nardo, Il Commentariolum Petitionis (Padua 1970) 1–37, and the bibliographical survey by J.-M. Davies et al. in Aufstieg und Niedergang der römischen Welt 1.3(1973). 239–77.
There still appears to be no consensus on the question of authorship. If the treatise is indeed apocryphal, it is on a very different level from the other ‘forgeries’ in this volume.
