A Dictionary of Greek and Roman biography and mythology

18. M.Antonius, M. F. M. N., called by the Greek writers Antyllus (Ἄντυλλος), which is probably only a corrupt form for Antonillus (young Antonius), was the elder of the two sons of the triumvir by his wife Fulvia. In B. C. 36, while he was still a child, he was betrothed to Julia, the daughter of Caesar Octavianus. After the battle of Actium, when Antony despaired of success at Alexandria, he conferred upon his son Marcus the toga virilis (B. C. 30), that he might be able to take his place in case of his death. He sent him with proposals of peace to Caesar, which were rejected ; and on his death, shortly after, young Marcus was executed by order of Caesar. (D. C. 48.54, 51.6, 8, 15; Suet. Aug. 17, 63; Plut. Ant. 71, 81, 87.)
