But Charimenes the seer took on a partner in the enterprise, at which Aeschylus and his friends were incensed and proceeded to act on their own account, ignoring Charimenes. When Charimenes was aware of this, he was angry and informed against the men just as they were setting out to attack the tyrant; most of them, however, succeeded in escaping from the market-place and fled to Corinth.
Nevertheless, after a little while Aristomachus was killed by slaves, and Aristippus, a more pernicious tyrant than he, soon succeeded in seizing the power. Aratus at once took all the Achaeans of military age who were at hand and went swiftly to the aid of the city, supposing that he would be welcomed by the Argives.
But since most of them were by this time habituated to slavery and willing to endure it, so that not a man came over to his side, he retired, after involving the Achaeans in the charge of having gone to war in time of peace. They were prosecuted on this charge before the Mantineans, and in the absence of Aratus, Aristippus as plaintiff won his case and was awarded damages to the amount of thirty minas.[*](Half a talent, equivalent to about £118 or $600, a merely nominal fine. Mantineia acted as arbitrator,perhaps by special agreement.)
Aratus himself the tyrant both hated and feared, and so laid plots to kill him with the assistance of Antigonus the king; and almost everywhere there were men who undertook this deed for them and watched for an opportunity.
