sieges ; and if the Argive chiefs under Adrastos are not so successful
as Herakles with his six ships at lUon, still the Trojan power was no
more destroyed by the latter than that of Eteokles was crushed by
Polyneikes and his allies. In either case also there is a hero whose
presence is indispensable to the success of the enterprise. In the
Theban story this hero is Aniphiaraos, the Achilleus of the Trojan
legend in this its most important feature : and as Troy cannot fall
unless Achilleus fights against it, so the Argives cannot hope to take
Thebes unless Amphiaraos goes with them. But as neither Achilleus
nor Odysseus wished to fight in a quarrel which was not their own,
so Amphiaraos shrinks from any concern in a contest in which the
prophetic mind inherited by him from his ancestor Melampous tells
him that all the chiefs engaged in it must die with the one exception
of Adrastos. But he had promised the Argive king that in any
differences which might arise between them he would abide by the
decision of his wife Eriphyle, and Eriphyle had been bribed by
Polyneikes with the gift of the necklace and peplos of Harmonia to
decide in favour of the expedition. Thus Amphiaraos departs for
Thebes with a presentiment of his own coming doom as strong as the
consciousness of Achilleus that his career must be brief; but before
he sets out, he charges his sons Amphilochos and Alkmaion to slay
their mother, so soon as they hear of his death, and to march against
the hated city of Thebes ; and thus the starting-point was furnished
not only for the Theban war, but for a new series of woes to be
wrought by the Erinyes of Eriphyle.
The germs of the rivalry, which in the case of the sons of Oidipous of Oidipous, grew mto a deadly hatred, are seen in the points of contrast afforded by almost all the correlative deities of Greek and Vedic mythology, and the twin heroes whether of the east or the west.^ Thus there is a close parallel between the Dioskouroi and the sons of Oidipous. The former may not be seen together ; the latter agree to reign over Thebes in turn ; and it was a ready device to account for the sub- sequent feud by saying that the brother whose time was over refused to abide by his compact Hence Polyneikes became an exile ; but it is not easy to determine precisely to what degree a purely moral element has forced its way into this series of legends from the horror which a union like that of lokaste and Oidipous, when regarded as a
