In one of the preceding chapters, we have traced the descending series of the two most distinguished mythical families in Peloponnêsus,—the Perseids and the Pelopids: we have followed the former down to Hêraklês and his son Hyllus, and the latter down to Orestês son of Agamemnôn, who is left in possession of that ascendancy in the peninsula which had procured for his father the chief command in the Trojan war. The Herakleids, or sons of Hêraklês, on the other hand, are expelled fugitives, dependent upon foreign aid or protection: Hyllus had perished in single combat with Echemus of Tegea, (connected with the Pelopids by marriage with Timandra sister of Klytæmnêstra,[1]) and a solemn compact had been made, as the preliminary condition of this duel, that no similar attempt at an invasion of the peninsula should be undertaken by his family for the space of one hundred years. At the end of the stipulated period the attempt was renewed, and with complete success; but its success was owing, not so much to the valor of the invaders as to a powerful body of new allies. The Herakleids reappear as leaders and companions of the Dorians,—a northerly section of the Greek name, who now first come into importance,—poor, indeed, in mythical renown, since they are never noticed in the Iliad, and only once casually mentioned in the Odyssey, as a fraction among the many-tongued inhabitants of Krête,—but destined to form one of the grand and predominant elements throughout all the career of historical Hellas.
