1. One of the original inhabitants of Laconia which was called after him, its first king, Lelegia. He was married to the Naiad Cleochareia, by whom he became the father of Myles, Polycaon, and Eurotas. He had a heroum at Sparta. (Apollod. iii 10. § 3; Paus. iii. 1. § 1. 12. § 4, iv. 1. § 2.) Some call his wife Peridia, and his children Myles, Polyclon, Bomolochus, and Therapne; while Eurotas is represented as a son of Myles and a grandson of Lelex. (Schol. ad Eurip. Orest. 615.) In other traditions, again, Lelex is described as a son of Spartus, and as the father of Amyclas. (Steph. Byz. s. v. Lakedaimôn.)

2. A son of Poseidon and Libya, the daughter of Epaphus. He was regarded as the ancestor of the Leleges, and is said to have immigrated from Egypt into Greece, where he became king of Megara; and his tomb was shown below Nisaea, the acropolis of Megara. (Paus. i. 44. § 5, 39. § 5; Ov. Met. vii. 443, viii. 567, 617.)

3. One of the Calydonian hunters. (Ov. Met. viii. 312.)
