22. CN. CALFURNIUS CN. F. CN. N. PISO, consul B. C. 23, was, in all probability, the son of No. 21. He belonged to the high aristocratical party, and was naturally of a proud and imperious temper. He fought against Caesar in Africa, in B. C. 46, and after the death of the dictator, joined Brutus and Cassius. He was subsequently pardoned, and returned to Rome; but he disdained to ask Augustus for any of the honours of the state, and was, without solicitation, raised to the consulship in B. C. 23. (Tac. Ann. 2.43, Bell. Afr. 18.) This Cn. Piso appears to be the same as the Cn. Piso spoken of by Valerius Maximus (6.2.4).
