First, I think that I ought to explain to you in what way we acquired Messene , and for what reasons you settled in the
 Peloponnesus—you who from of old are Dorians. And the reason why I shall go back to remote
 times is that you may understand why your enemies are trying to rob you of this country,
 which you acquired, no less than Lacedaemon 
 itself, with a just title. When Heracles had put off this life and from being mortal became a god, his sons at
 first went on divers wanderings and faced many perils because of the power of their
 enemies; For the return of the the sons of Heracles and
 details connected therewith see Apollod. 2.8.2-4 , and
 Frazer’s notes on this passage (Loeb Classical Library, Vol.I). Cf. Isoc. 4.54-58 and notes. but after the death of Eurystheus they fixed
 their habitation among the Dorians. In the third generation thereafter they came to
 Delphi , desiring to consult the oracle about
 certain matters. Apollo, however, made them no answer to the questions which they asked,
 but merely bade them seek the country of their fathers. Searching into the meaning of the oracle, they found, first, that Argos belonged to them by right of their being next of
 kin, for after the death of Eurystheus they were the sole survivors of Perseus’ line; Sthenelus, father of Eurystheus, was a son of Perseus. For the
 manner of Eurystheus’ death see Isoc. 4.60 . next,
 that Lacedaemon was theirs by right of gift, for
 when Tyndareus, having been driven from his throne, Tyndareus, son of Perieres and of Perseus’ daughter, Gorgophone, was king of Lacedaemon until driven out by his half-brother
 Hippocoön and by Hippocoön’s sons. See Apollod.
 3.10.5 . was restored to it by Heracles, Heracles slew Hippocoön and his twenty sons and restored Tyndareus. after Castor
 and Polydeuces had vanished from among men, Castor was
 slain during a foray in Messene . His
 brother, Polydeuces, who according to most accounts was a son of Zeus by Leda, while
 Castor was a son of Tyndareus by Leda, refused to accept immortality unless it was
 shared by his brother. Zeus, therefore, granted that the two brothers dwell, on
 alternate days, among the gods and among men. According to others both were sons of
 Zeus. Hence Isocrates can refer to their kinship with Heracles, the son of Zeus and
 Alcmene. See Apollod. 3.11.2 and Isoc. 10.61 . he gave the land to Heracles because of this act of
 kindness and also because of the kinship of Heracles and his own sons; and lastly, they found that Messene was
 theirs as a prize taken in war, for Heracles, when he had been robbed of the cattle from
 Erytheia, To fetch the cattle of Geryon from Erytheia, an
 island off the coast of Spain , was the tenth
 labor imposed on Heracles by Eurystheus. See Apollod.
 2.5.10 . by Neleus and all his sons except Nestor, had taken the country
 captive and slain the offenders, but had committed the city to Nestor’s charge, believing
 him to be prudent, because, although the youngest of his brethren, he had taken no part in
 their iniquity. Assuming this to be the purport of the oracle, they joined forces with your forefathers
 and organized an army, sharing meantime their own country with their followers, That is, the common folk of the Dorians as distinguished from
 the descendants of Heracles, the ancestors of Archidamus. but receiving from them
 the kingship as the prize reserved for themselves alone; then having confirmed these
 covenants by mutual pledges, they set out upon the expedition.
