This Battus had a son Arcesilaus; on his first coming to reign, he quarrelled with his brothers, until they left him and went away to another place in Libya, where they founded a city for themselves, which was then and is now called Barce; and while they were founding it, they persuaded the Libyans to revolt from the Cyrenaeans. [2] Then Arcesilaus led an army into the country of the Libyans who had received his brothers and had also revolted; and they fled in fear of him to the eastern Libyans. [3] Arcesilaus pursued them until he came in his pursuit to Leucon in Libya, where the Libyans resolved to attack him; they engaged, and so wholly overcame the Cyrenaeans that seven thousand Cyrenaean soldiers were killed there. [4] After this disaster, Arcesilaus, being worn down and having taken a drug, was strangled by his brother Learchus; Learchus was deftly killed by Arcesilaus' wife, Eryxo.
