Arcesilaus' kingship passed to his son Battus, who was lame and infirm in his feet. The Cyrenaeans, in view of the affliction that had overtaken them, sent to Delphi to ask what political arrangement would enable them to live best; the priestess told them bring a mediator from Mantinea in Arcadia. When the Cyrenaeans sent their request, the Mantineans gave them their most valued citizen, whose name was Demonax. When this man came to Cyrene and learned everything, he divided the people into three tribes; of which the Theraeans and dispossessed Libyans were one, the Peloponnesians and Cretans the second, and all the islanders the third; furthermore, he set apart certain domains and priesthoods for their king Battus, but all the rest, which had belonged to the kings, were now to be held by the people in common.
