19. JULUS ANTONIUS, M. F. M. N., the younger son of the triumvir by Fulvia, was brought up by his step-mother Octavia at Rome, and after his father's death (B. C. 30) received great marks of favour from Augustus, through the influence of Octavia. (Plut. Ant. 87; D. C. 51.15.) Augustus married him to Marcella, the daughter of Octavia by her first husband, C. Marcellus, conferred upon him the praetorship in B. C. 13, and the consulship in B. C. 10. (Vell. 2.100 ; D. C. 54.26, 36; Suet. Cl. 2.) In consequence of his adulterous intercourse with Julia, the daughter of Augustus, he was condemned to death by the emperor in B. C. 2, but seems to have anticipated his execution by a voluntary death. He was also accused of aiming at the empire. (D. C. 55.10; Senec. de Brevit. Vit. 5; Tac. Ann. 4.44, 3.18; Plin. Nat. 7.46; Vell. Pat. l.c.) Antonius was a poet, as we learn from one of Horace's odes (4.2), which is addressed to him.
