Æpytus is descended on the father's side from Hercules, Perseus, and the kings of Argos; on the mother's side from Pelasgus, and the aboriginal kings of Arcadia. Callisto, the daughter of the wicked Lycaon, and the mother, by Zeus, of Areas, from whom the Arcadians took their name, was the granddaughter of Pelasgus. The birth of Arcas brought upon Callisto the anger of the virgin-goddess Artemis, whose service she followed: she was changed into a she-bear, and in this form was chased by her own son, grown to manhood. Zeus interposed, and the mother and son were removed from the earth, and placed among the stars. Callisto became the famous constellation of the Great Bear; her son became Arcturus, Arctophylax, or Boötes. From this son of Callisto were descended Cypselus, the maternal grandfather of Æpytus, and the children of Cypselus, Laias and Merope.
The story of the life of Hercules, the paternal ancestor of Æpytus, is so well known that there is no need to record it. The reader will remember that, although entitled to the throne of Argos by right of descent from Perseus and Danaus, and to the thrones of Sparta and Messenia by right of conquest, Hercules yet passed his life in labors and wanderings, subjected by the decree of fate to the commands of his kinsman, the feeble and malignant Eurystheus. At his death he bequeathed to his offspring, the Heracleidæ, his own claims to the kingdoms of Peloponnesus, and to the persecution of Eurystheus. They at first sought shelter with Ceyx, king of Trachis; he was too weak to protect them, and they then took refuge at Athens. The Athenians refused to deliver them up at the demand of Eurystheus; he invaded Attica, and a battle was fought near Marathon, in which, after Macaria, a daughter of Hercules, had devoted herself for the preservation of her house, Eurystheus fell, and the Heracleidæ and their Athenian protectors were victorious. The memory of Macaria's self-sacrifices was perpetuated by the name of a spring of water on the plain of Marathon, the spring Macaria. The Heracleidæ then endeavored to effect their return to Peloponnesus. Hyllus, the eldest of them, inquired of the oracle at Delphi respecting their return; he was told to return by the narrow passage and in the third harvest. Accordingly, in the third year from that time Hyllus led an army to the Isthmus of Corinth; but there he was encountered by an army of Achaians and Arcadians, and fell in single combat with Echemus, king of Tegea. Upon this defeat the Heracleidæ retired to northern Greece; there, after much
