And since his son said that he would not sail with him, therefore he said that he would leave him behind as a sheep among wolves; and in accordance with that saying this young man got the name of Oiolycos, 131 and it chanced that this name prevailed over his former name: then from Oiolycos was begotten Aigeus, after whom are called the Aigeidai, a powerful clan 132 in Sparta: and the men of this tribe, since their children did not live to grow up, established by the suggestion of an oracle a temple to the Avenging Deities 133 of Laïos and OEdipus, and after this the same thing was continued 134 in Thera by the descendants of these men.
150. Up to this point of the story the Lacedemonians agree in their report with the men of Thera; but in what is to come it is those of Thera alone who report that it happened as follows. Grinnos 135 the son of Aisanios, a descendant of the Theras who has been mentioned, and king of the island of Thera, came to Delphi bringing the offering of a hecatomb from his State; and there were accompanying him, besides others of the citizens, also Battos the son of Polymnestos, who was by descent of the family of Euphemos 136 of the race of the Minyai. Now when Grinnos the king of the Theraians was consulting the Oracle about other matters, the Pythian prophetess gave answer bidding him found a city in Libya; and he made reply saying: "Lord, 137 I am by this time somewhat old and heavy to stir, but do thou bid some one of these younger ones do this." As he thus said he pointed towards Battos. So far at that time: but afterwards when he had come away they were in difficulty about the saying of the Oracle, neither having any knowledge of Libya, in what part of the earth it was, nor venturing to send a colony to the unknown.
151. Then after this for seven years there was no rain in Thera, and in these years all the trees in their island were withered up excepting one: and when the Theraians consulted the Oracle, the Pythian prophetess alleged this matter of colonising Libya to be the cause. As then they had no remedy for their evil, they sent messengers to Crete, to find out whether any of the Cretans or of the sojourners in Crete had ever come to Libya. These as they wandered round about the country came also the city of Itanos, and there they met with a fisher for purple named Corobios, who said that he had been carried away by winds and had come to Libya, and in Libya to the island of Platea. This man they persuaded by payment of money and took him to Thera, and from Thera there set sail men to explore, at first not many in number; and Corobios having guided them to this same island of Platea, they left Corobios there, leaving behind with him provisions for a certain number of months, and sailed themselves as quickly as possible to make report about the island to the men of Thera.
