was promoted by Vitellius from the command of a squadron of cavalry to be admiral of the fleet at Ravenna and Misenum, B. C. 70; but disappointed at not obtaining the command of the praetorian troops, he betrayed the fleet to Vespasian. After the death of Vitellius, Bassus was sent to put down some disturbances in Campania. (Tac. Hist. 2.100, 3.12, 36, 40, 4.3.) His name occurs in an inscription. (Gruter, p. 573.)
