So the Libyans led them from that place making them start towards evening; and in order that the Hellenes might not see the fairest of all the regions as they passed through it, they led them past it by night, having calculated the time of daylight: and this region is called Irasa. Then having conducted them to the so-called spring of Apollo, they said, "Hellenes, here is a fit place for you to dwell, for here the heaven is pierced with holes."

Now during the lifetime of the first settler Battos, who reigned forty years, and of his son Arkesilaos, who reigned sixteen years, the Kyrenians continued to dwell there with the same number as 142 when they first set forth to the colony; but in the time of the third king, called Battos the Prosperous, the Pythian prophetess gave an oracle wherein she urged the Hellenes in general to sail and join with the Kyrenians in colonising Libya. For the Kyrenians invited them, giving promise of a division of land; and the oracle which she uttered was as follows:
"Who to the land much desirèd, to Libya, afterwards cometh, After the land be divided, 143 I say he shall some day repent it."
Then great numbers were gathered at Kyrene, and the Libyans who dwelt round had much land cut off from their possessions; therefore they with their king whose name was Adicran, as they were not only deprived of their country but also were dealt with very insolently by the Kyrenians, sent to Egypt and delivered themselves over to Apries king of Egypt. He then having gathered a great army of Egyptians, sent it against Kyrene; and the men of Kyrene marched out to the region of Irasa and to the spring Theste, 144 and there both joined battle with the Egyptians and defeated them in the battle: for since the Egyptians had not before made trial of the Hellenes in fight and therefore despised them, they were so slaughtered that but few of them returned back to Egypt. In consequence of this and because they laid the blame of it upon Apries, the Egyptians revolted from him.

This Battos had a son called Arkesilaos, who first when he became king made a quarrel with his own brothers, until they finally departed to another region of Libya, and making the venture for themselves founded that city which was then and is now called Barca; and at the same time as they founded this, they induced the Libyans to revolt from the Kyrenians. After this, Arkesilaos made an expedition against those Libyans who had received them and who had also revolted from Kyrene, and the Libyans fearing him departed and fled towards the Eastern tribes of Libyans: and Arkesilaos followed after them as they fled, until he arrived in his pursuit at Leucon in Libya, and there the Libyans resolved to attack him. Accordingly they engaged battle and defeated the Kyrenians so utterly that seven thousand hoplites of the Kyrenians fell there. After this disaster Arkesilaos, being sick and having swallowed a potion, was strangled by his brother Haliarchos, 145 and Haliarchos was killed treacherously by the wife of Arkesilaos, whose name was Eryxo.
