The Bobiensian scholiast tells us that the speech Pro Archia was delivered by Cicero in a court presided over by his brother Quintus as praetor, who held this office in 62 B.C. The scholiast makes two clear references to Quintus (ad Pro Archia 3):
(a) Archias presented this case, dealing with the Papian law on Roman citizenship, in the court of Quintus Cicero, the brother of this Marcus Tullius …
(b) It is significant that he makes mention of the praetor himself, that is of his brother Quintus Cicero, who was in charge of the trial. Indeed, it is most appropriate that he speaks in praise of a fine poet in the court of someone who takes pleasure in pursuits of this kind, for Quintus Cicero was a writer not only of epic, but also of tragedy.
