Nicolaus of Damascus, Life of Augustus 31. It has been speculated that Agrippa was among the negotiators who won over Antony's Macedonian legions to Octavian, but there is no direct evidence for this; see Reinhold, p. 16.
Dio54.28.3 places Agrippa's death in late March 12 BC, while Pliny the Elder7.46 states that he died "in his fifty-first year". Depending on whether Pliny meant that Agrippa was aged 50 or 51 at his death, this gives a date of birth between March 64 and March 62. A calendar from Cyprus or Syria includes a month named after Agrippa beginning on November 1, which may reflect the month of his birth. See Reinhold, pp. 2–4; Roddaz, pp. 23–26.
Dio 50.14.1–2; cf. Velleius Paterculus 2.84.2 ("Agrippa ... before the final conflict had twice defeated the fleet of the enemy"). Dio is wrong to say that Sosius was killed, since he in fact fought at and survived the Battle of Actium (Reinhold, p. 54 n. 14; Roddaz, p. 163 n. 140).
