Cithaeronian lion

Alcathous (/ælˈkæθoʊ.əs/; Ancient Greek: Ἀλκάθοος) was in Greek mythology the son of Pelops and Hippodamia, and brother of Atreus and Thyestes. He first married Pyrgo and afterwards Euaechme, and was the father of Ischepolis (Ἰσχέπολις), Callipolis (Καλλίπολις), Iphinoe (Ἰφινόη), Periboea (Περίβοια), and Automedusa (Αὐτομέδουσα).

Pausanias relates that after Euippus, son of king Megareus, was killed by the Cythaeronian lion, Megareus, whose elder son Timalcus had likewise fallen by the hands of Theseus, offered his daughter Euaechme and his kingdom to anyone who could slay the lion. Alcathous undertook the task, killed the lion, and thus obtained Euaechme for his wife, and afterwards became the successor of Megareus. In gratitude for this success, he built at Megara a temple of Artemis Agrotera and Apollo Agraeus. He also restored the walls of Megara, which had been destroyed by the Cretans. In this work he was said to have been assisted by Apollo, and the stone upon which the god used to place his lyre while he was at work, was even in late times believed to produce a sound similar to that of a lyre when struck.
