23. Surnamed PHILADELPHUS, a son of M. Antony, the Triumvir, by Cleopatra. He was the youngest of their three children, and could therefore hardly have been born before B. C. 39. (D. C. 49.32.) In B. C. 34, he was proclaimed by his father king of Syria, including Cilicia, and all the provinces west of the Euphrates (D. C. 49.41; Pint. Ant. 54). After the death of Antony, and the subjugation of Egypt, B. C. 30, his life was spared by Augustus, at the intercession of Juba and Cleopatra, and he was brought up by Octavia with her own children, but we hear nothing more of him. (D. C. 51.15; Plut. Ant. 87.)
