2. Pĕlĭas, ae (nom. Pelia, Sen. Med. 201; 276), m., = Πελίας, a king of Thessaly, son of Neptune and the nymph Tyro, brother of Neleus, half-brother of Æson, and father of Acastus. Being appointed by Æson guardian to his son Jason, he sought, when Jason grew up, to rid himself of the charge by inciting him to join the Argonautic expedition. After Jason’s return Pelias was slain by his own daughters, at the artful instigation of Medea, Plaut. Ps. 3, 2, 80; Hyg. Fab. 24; Enn. ap. Auct. Her. 2, 22, 34 (Trag. v. 286 Vahl.); id. ap. Cic. de Or. 3, 58, 217 (id. v. 313 ib.); Ov. M. 7, 304; Val. Fl. 1, 22 et saep.
Hence, Pĕlĭădes, the daughters of Pelias, who, upon Medea’s promise to restore their father’s youth, cut him to pieces, and boiled him in a caldron, Phaedr. 4, 7, 16; cf. Hyg. Fab. 24.
