was a native of Forum Julii, where he possessed considerable estates. He was a friend of Vespasian's before his accession; and having previously served as tribune of the praetorian tribunes, he was able to collect for Vespasian many of the Vitellian troops in Narbonnese Gaul, of which province he was appointed procurator, A. D. 69. He also served in the Jewish war, and was eventually raised to the consulship in the reign of Trajan, A.D. 101. He was a friend and correspondent of the younger Pliny, who has addressed five of his letters to him (Tac. Hist. 3.42, 43; Joseph. B. J. iii. (14), 7.1; Plin. Ep. 2.2, 4.16, 5.19, 9.3, 37.)
