（*)Alkibia/dhs), the son of Cleinias, was born at Athens about B. C. 450, or a little earlier. His father fell at Coroneia B. C. 447, leaving Alcibiades and a younger son. (Plat. Protag. p. 320a.)
The last campaign of the war with Potidaea was in B. C. 429. Now as Alcibiades served in this war, and the young Athenians were not sent out on foreign military service before they had attained their 20th year, he could not have been born later than B. C. 449. If he served in the first campaign (B. C. 432), he must have been at least five years old at the time of his father's death. Nepos (Alcib. 10) says he was about forty years old at the time of his death (B. C. 404), and his mistake has been copied by Mitford.
Alcibiades was connected by birth with the noblest families of Athens. Through his father he traced his descent from Eurysaces, the son of Ajax (Plat. Alcib. I. p. 121), and through him from Aeacus and Zeus. His mother, Deinomache, was the daughter of Megacles, the
uthority of Aeschines the Socratic, speaks of a capital prosecution instituted against him on extremely weak grounds. Aristeides, who was his cousin, was a witness on the trial, which must therefore have tatken place before B. C. 468, the probable date of Aristeides' death. In Herodotus (7.151) Callias is mentioned as ambassador from Athens to Artaxerxes; and this statement we might identify with that of Diodorus, who ascribes to the victories of Cimon, through the negotiation of Callias, B. C. 449, a peace with Persia on terms most humiliating to the latter, were it not that extreme suspicion rests on the whole account of the treaty in question. (Paus. 1.8; Diod. 12.4; Wesselling, ad loc.; Mitford's Greece, ch. xi. sec. 3, note 11; Thirlwall's Greece, vol. iii. pp. 37, 38, and the authorities there referred to; Böckh, Publ.
