Asconius believed he had access to two published editions of Cicero’s defence of Milo. The first purported to be a record of the speech as delivered at the trial, in which Cicero was not at his best. The second edition was regarded by Asconius as Cicero’s supreme achievement in oratory. This edition is that which we still have; the first has perished, and it has even been suggested that Asconius — and Quintilian — were duped by a forgery. Even so Asconius’ knowledge of Cicero’s line of defence in the trial cannot have depended on the text of this supposed verbatim record alone, but rather on an ample historiography on which he drew for the long and circumstantial argumentum to his Milonian commentary. (A forger, for that matter, who could impose on Asconius and Quintilian must also have been historically well informed about the case.) Any indication by Asconius, therefore, of a divergence between the original defence and the extant version is likely to rest on specific knowledge.
