In his discharge of these commissions he visited the different petty republics of Greece. At one time he is found in Corinth, and at another in Athens, endeavoring, by the narration of some of his wise fables, to reconcile the inhabitants of those cities to the administration of their respective rulers, Pariander and Pisistratus.
