Lucius Arruntius was a Roman admiral. He saw action during the War with Sextus Pompeius, and the war of Mark Antony and Octavian (later named Augustus). He is most notable for his participation during the Battle of Actium, where he was in command of victorious Augustus' central division. He was also instrumental in convincing Octavian to pardon Gaius Sosius, one of Mark Antony's generals, after his capture.Ronald Syme, The Roman Revolution (Oxford: University Press, 1939), p. 297 Arruntius was consul in 22 BC as the colleague of Marcus Claudius Marcellus Aeserninus.Attilio Degrassi, I fasti consolari dell'Impero Romano dal 30 avanti Cristo al 613 dopo Cristo (Rome, 1952), p. 4
Life Arruntius came of an opulent family at the Volscian city of Atina. His wealth made him a target in the proscriptions of the Second Triumvirate, which he evaded by arming his clientes and slaves then fighting his way to the Italian coast, from whence he sailed to join the forces of Sextus Pompeius.Syme, Roman Revolution, p. 194 At some point after the Pact of Misenum was concluded in 39 BC, Arruntius was one of several Pompeians who switched sides and became a supporter of Octavian.Syme, Roman Revolution, p. 282
Martha Hoffman Lewis included Arruntius among those elevated to patrician status in 29 BC.Hoffman Lewis, The Official Priests of Rome, p. 50 He attended the Ludi Saeculares in 17 BC according to an inscription as a quindecimviri sacris faciundis. = ILS 5050 According to Gaius Stern, he appears on the Ara Pacis within the college of the quindecimviri sacris faciundis.
A Lucius Arruntius is also mentioned in Seneca's Epistulae morales ad Lucilium as an imitator of Sallustius' literary style and as the author of a historical work on the Punic War.Epistulae morales, 114.17 This could either be the Arruntius mentioned above or his son.
Family He had a son, Lucius Arruntius, consul AD 6, who played a prominent role in the Senate after Augustus died.
