=Adrastus=, son of Talaus and Lysimache, was king of Argos. Polynices, being banished from Thebes by his brother Eteocles, fled to Argos, where he married Argia daughter of Adrastus. The king assisted his son-in-law, and marched against Thebes with an army headed by seven of his most famous generals. All perished in the war except Adrastus, who, with a few men saved from slaughter, fled to Athens, and implored the aid of Theseus against the Thebans, who opposed the burying of the Argives slain in battle. Theseus went to his assistance, and was victorious. Adrastus, after a long reign, died through grief, occasioned by the death of his son Ægialeus. A temple was raised to his memory at Sicyon, where a solemn festival was annually celebrated. _Homer_, _Iliad_, bk. 5.――_Virgil_, _Æneid_, bk. 6, li. 480.――_Apollodorus_, bk. 1, ch. 9; bk. 3, ch. 7.―― _Statius_, _Thebiad_, bks. 4 & 5.――_Hyginus_, fables 68, 69, & 70. ――_Pausanias_, bk. 1, ch. 39; bk. 8, ch. 25; bk. 10; ch. 90.―― _Herodotus_, bk. 5, ch. 67, &c.――――A peripatetic philosopher, disciple to Aristotle.
