Book 1
7.8
Evenus begat Marpessa, who was wooed by Apollo, but Idas, son of Aphareus, carried her off in a winged chariot which he received from Poseidon.As to Evenus and Marpessa, see Scholiast on Hom. Il. ix.557; Eustathius on Hom. Il. ix.557 p. 776; Plut. Lives. 40; Hyginus, Fab. 242 (who calls Evenus a son of Herakles). According to the first two of these writers, Evenus, like Oenomaus, used to set his daughter's suitors to run a chariot race with him, promising to bestow her on the winner; but he cut off the heads of his vanquished competitors and nailed them to the walls of his house. This seems to be the version of the story which Apollodorus had before him, though he has abridged it. Pursuing him in a chariot, Evenus came to the river Lycormas, but when he could not catch him he slaughtered his horses and threw himself into the river, and the river is called Evenus after him.
7.9
But Idas came to Messene, and Apollo, falling in with him, would have robbed him of the damsel. As they fought for the girl's hand, Zeus parted them and allowed the maiden herself to choose which of the two she would marry; and she, because she feared that Apollo might desert her in her old age, chose Idas for her husband.Compare Scholiast on Hom. Il. ix.557 (who cites Simonides); Eustathius on Hom. Il. ix.557 p. 776; Tzetzes, Scholiast on Lycophron 561; Paus. 5.18.2.
7.10
Thestius had daughters and sons by Eurythemis, daughter of Cleoboea: the daughters were Althaea, Leda, Paus. 3.13.8 agrees with Apollodorus in saying that Leda was the daughter of Thestius, who was a son of Agenor, who was a son of Pleuron; and he cites the epic poem of Areus as his authority for the genealogy. Hypermnestra, and the males were Iphiclus, Evippus, Plexippus, and Eurypylus. Porthaon and Euryte, daughter of Hippodamas, had sons, Oeneus, Agrius, Alcathous, Melas, Leucopeus, and a daughter Sterope, who is said to have been the mother of the Sirens by Achelous.
