he himself privately offered him double the amount of the pension which he received from King Ptolemy of Egypt. However, as Aratus refused to listen to his overtures, but sent his own son with the other hostages to Antigonus, and persuaded the Achæans to pass a decree to hand over the Acro-Corinthus to Antigonus, Kleomenes invaded the territory of Sikyon and laid it waste, and also took the property of Aratus when it was publicly presented to him by the people of Corinth. XX. When Antigonus crossed the Geranean mountains with a large force, Kleomenes did not think it necessary to guard the isthmus, but determined to fortify the mountains called Onea, and by holding that strong position, to protract the war and wear out the Macedonian force, rather than fight a pitched battle with their phalanx. By this line of policy he reduced Antigonus to great straits; for he had made no preparations for feeding his troops for more than a short time, and yet to force his way in over the isthmus was a difficult operation while Kleomenes barred the way. An attempt which he made to steal through by Lechæum[13] at night was repulsed with considerable loss; so that Kleomenes and his friends, elated by their victory, supped merrily together, while Antigonus was at his wit's end to know what to do. He even began to meditate marching to the promontory of Heræum, and conveying his forces over the Corinthian gulf to Sikyon, an operation which would have required much time and many ships. However, late in the evening there arrived certain friends of Aratus by sea from Argos, inviting him to come thither, as the Argives intended to revolt from Kleomenes. The prime mover in this revolt was one Aristoteles, who easily prevailed upon the people to rise, because they were disappointed with Kleomenes, who had not cancelled all their debts as they hoped he would. Aratus now took fifteen hundred of Antigonus's soldiers and proceeded by sea to Epidaurus. Aristoteles however did not wait for his arrival, but led the citizens to attack the garrison in the citadel, assisted by Timoxenus with a body of Achæans from Sikyon.
