All the sons of Eurystheus lost their lives in the battle along with him, so that the Perseid family was now represented only by the Hêrakleids, who collected an army and endeavored to recover the possessions from which they had been expelled. The united forces of Iônians, Achæans, and Arcadians, then inhabiting Peloponnêsus, met the invaders at the isthmus, when Hyllos, the eldest of the sons of Hêraklês, proposed that the contest should be determined by a single combat between himself and any champion of the opposing army. It was agreed, that if Hyllos were victorious, the Hêrakleids should be restored to their possessions—if he were vanquished, that they should forego all claim for the space of a hundred years, or fifty years, or three generations,—for in the specification of the time, accounts differ. Echemos, the hero of Tegea in Arcadia, accepted the challenge, and Hyllos was slain in the encounter; in consequence of which the Hêrakleids retired, and resided along with the Dôrians under the protection of Ægimios, son of Dôrus.[211] As soon as the stipulated period of truce had expired, they renewed their attempt upon Peloponnêsus conjointly with the Dôrians, and with complete success: the great Dôrian establishments of Argos, Sparta, and Messênia were the result. The details of this victorious invasion will be hereafter recounted. [211] Herodot. ix. 26; Diodôr. iv. 58. Sikyôn, Phlios, Epidauros, and Trœzen[212] all boasted of respected eponyms and a genealogy of dignified length, not exempt from the usual discrepancies—but all just as much entitled to a place on the tablet of history as the more renowned Æolids or Hêrakleids. I omit them here because I wish to impress upon the reader’s mind the salient features and character of the legendary world,—not to load his memory with a full list of legendary names. [212] Pausan. ii. 5, 5; 12, 5; 26, 3. His statements indicate how much the predominance of a powerful neighbor like Argos tended to alter the genealogies of these inferior towns. CHAPTER V. DEUKALION, HELLEN, AND SONS OF HELLEN. In the Hesiodic Theogony, as well as in the “Works and Days,” the legend of Promêtheus and Epimêtheus presents an import religious, ethical, and social, and in this sense it is carried forward by Æschylus; but to neither of the characters is any genealogical function assigned. The Hesiodic Catalogue of Women brought both of them into the stream of Grecian legendary lineage, representing Deukaliôn as the son of Promêtheus and Pandôra, and seemingly his wife Pyrrha as daughter of Epimêtheus.[213] [213] Schol. ad Apollôn. Rhod. iii. 1085. Other accounts of the genealogy of Deukaliôn are given in the Schol. ad Homer. Odyss. x. 2, on the authority both of Hesiod and Akusilaus.
