[385] Odyss. iii. 260-275; iv. 512-537; xi. 408. Deinias in his Argolica, and other historians of that territory, fixed the precise day of the murder of Agamemnôn,—the thirteenth of the month Gamêliôn (Schol. ad Sophokl. Elektr. 275). For seven years Ægisthus and Klytæmnêstra reigned in tranquillity at Mykênæ on the throne of the murdered Agamemnôn. But in the eighth year the retribution announced by the gods overtook them: Orestês, grown to manhood, returned and avenged his father by killing Ægisthus, according to Homer; subsequent poets add, his mother also. He recovered the kingdom of Mykênæ, and succeeded Menelaus in that of Sparta. Hermionê, the only daughter of Menelaus and Helen, was sent into the realm of the Myrmidons in Thessaly, as the bride of Neoptolemus, son of Achilles, according to the promise made by her father during the siege of Troy.[386] [386] Odyss. iii. 306; iv. 9 Here ends the Homeric legend of the Pelopids, the final act of Orestês being cited as one of unexampled glory.[387] Later poets made many additions: they dwelt upon his remorse and hardly-earned pardon for the murder of his mother, and upon his devoted friendship for Pylades; they wove many interesting tales, too, respecting his sisters Iphigeneia and Elektra and his cousin Hermionê,—names which have become naturalized in every climate and incorporated with every form of poetry. [387] Odyss. i. 299. These poets did not at all scruple to depart from Homer, and to give other genealogies of their own, with respect to the chief persons of the Pelopid family. In the Iliad and Odyssey, Agamemnôn is son of Atreus: in the Hesiodic Eoiai and in Stesichorus, he is son of Pleisthenês the son of Atreus.[388] In Homer, he is specially marked as reigning at Mykênæ; but Stesichorus, Simonidês and Pindar[389] represented him as having both resided and perished at Sparta or at Amyklæ. According to the ancient Cyprian Verses, Helen was represented as the daughter of Zeus and Nemesis: in one of the Hesiodic poems she was introduced as an Oceanic nymph, daughter of Oceanus and Têthys.[390] The genealogical discrepancies, even as to the persons of the principal heroes and heroines, are far too numerous to be cited, nor is it necessary to advert to them, except as they bear upon the unavailing attempt to convert such legendary parentage into a basis of historical record or chronological calculation.

Elektr. 539, in reference to another discrepancy between Homer and the Hesiodic poems about the children of Helen, remarks that we ought not to divert our attention from that which is moral and salutary to ourselves in the poets (τὰ ἠθικὰ καὶ χρήσιμα ἡμῖν τοῖς ἐντυγχάνουσι), in order to cavil at their genealogical contradictions.
