HERACLES, he'-ra-cles (see HERCULES). HERACLIDA, he-ra-cli -dee, the direct de scendants of Hercilles (q.v.). The hero left to his son Hyllus his claims on the Peloponnesus, and allowed him to marry Eurytus's daughter 16Ie as soon as he came of age. The children of Hercules were obliged to take refuge from Eurystheus (q. v.) with King Ceyx of Tra chinfa, and next with King Theseus of Athens. The latter helped them against Eurystheus, whom Hyllus killed, thus acquiring the cities of Peloponnesus ; but a pestilence came, and an oracle informed the Heraclidw they had taken Peloponnesus before the appointed time. They returned to Attica, where Hyllus married Tole. From an ambiguous oracle, Hyllus made a second attempt on the Peloponnesus, and challenged King Atreus of Mycenm, Eurys theus's successor, to single combat ; and it was agreed that die victor should have undis turbed possession : in the duel Hyllus was killed. A third unsuccessful attempt was made by his son Cleodwus, whose son Aris tomgchus was killed in the fourth equally un successful attempt ; but the three sons of Aristomachus—Aristodemus, Tem6nus, and Cresphontes—encouraged by an oracle, in vaded Peloponnesus from Doris by land and sea, gained some victories, and divided it among them, 2104 B.C., sac years after Hyl
lus's first attempt. Aristodemus took Sparta, Temenus Argos, and Cresphontes Mycenx. IlEnAciaTus, /ze-m-c/i-tus. I. A cele brated philosopher of Ephesus, 510 B.C. He sought, like his predecessors, to reduce the universe to one principle or law, which he con sidered to be -yi'veale, the Becoming, or Change; holding that everything was in a continual flux, that nothing was for two moments the same. He delivered his tenets in obscure apophthegms, devoted himself to study, and lived an unsocial life. He died of dropsy, aged 6o: according to some, he was torn to pieces by dogs. 2.
