1. A son of Euaemon and Ops. (Hygin. Fab. 81.) He appears in the different traditions about him, as a hero of Ormenion, or Hyria, or as a king of Cyrene. In the Iliad he is represented as having led the men of Ormenion and other places to Troy with forty ships, and he is one of those who offer to fight with Hector. (ii. 734, vii. 167.) He slew many a Trojan, and when he himself was wounded by Paris, he was nursed and cured by Patroclus. (xi. 841, xv. 390; comp. Apollod. iii. 10. § 8 ; Hygin. Fab. 97; Ov. Met. xiii. 357.) According to a genealogy of the heroes of Ormenion he was a son of Hyperochus, and the father of Ormenus. (Schol. ad. Pind. Ol. vii. 42.) Among the heroes of Hyria, he is mentioned as a son of Poseidon and Celaeno, and went to Libya before Cyrene who fought against the lion that attacked his flocks, and in Libya he became connected with the Argonauts. (Schol. ad Apollon. Rhod. iv. 1561; Tzetz. ad Lycoph. 902.) He is said to have been married to Sterope, the daughter of Helios, by whom he became the father of Lycaon and Leucippus. (Schol. ad Pind. Pyth. iv. 57; Tzetz. ad Lycoph. 886.) The tradition which connects him with the legends about Dionysus, is given under AESYMNETES, and Eurypylus as connected with Dionysus, dedicated a sanctuary to Soteria at Patrae (Paus. vii. 21. § 2), which also contained a monument of him, and where sacrifices were offered to him every year after the festival of Dionysus (vii. 19. §§ 1, 3, ix. 41. § 1.) From Pausanias we learn that Eurypylus was called by some a son of Dexamenus. (Comp. Müller, Orchom. p. 341, &c., 2nd edit.)

2. A son of Poseidon and Astypalaea, was king of Cos, and was killed by Heracles who on his return from Troy landed in Cos, and being taken for a pirate, was attacked by its inhabitants. (Apollod. ii. 7. §§ 1, 8. ) According to another tradition Heracles attacked the island of Cos, in order to obtain possession of Chalciope, the daughter of Eurypylus, whom he loved. (Schol. ad Pind. Nem. iv. 40; comp. Hom. Il. ii. 676, xiv. 250 &c., xv. 25.)

3. A son of Telephus and Astyoche, was king of Moesia or Cilicia. Eurypylus was induced by the presents which Priam sent to his mother or wife, to assist the Trojans against the Greeks. Eurypylus killed Machaon, but was himself slain by Neoptolemus. (Hygin. Fab. 112; Strab. xiii. p. 584; Paus. iii. 26. 7; Dict. Cret. iv. 14; Eustath. ad Hom. p. 1697.)

4. There are three other mythical personages of this name. (Apollod. ii. 7. § 8, i. 7. § 10, 8. § 3.)
