one of the judices at Rome, an upright man, who displayed his integrity in the inquiry into the murder of Cluentius, B. C. 74, when C. Junius presided over the court. He was aedile elect with Cicero in B. C. 70, and consequently would not have been able to act as judex in the following year, as a magistrate was not allowed to discharge the duties of judex during his year of office. This was one reason among others why the friends of Verres were anxious to postpone his trial till B. C. 69. The praetorship of Caesonius is not mentioned, but he must have obtained it in the same year as Cicero, namely, B. C. 66, as Cicero writes to Atticus in 65, that there was some talk of Caesonius becoming a candidate with him for the consulship. (Cic. Verr. Act. 1.10 ; Pseudo-Ascon. in loc. ; Cic. Att. 1.1.) This Caesonius is probably the one whom Cicero speaks of in B. C. 45. (Ad Att. 12.11.)
