For he had not a sufficient store of provisions, and it was no easy matter to force his passage while Cleomenes sat entrenched. Moreover, when he attempted to slip past his enemy in the night by way of Lechaeum, he was driven out and lost some of his soldiers. Therefore Cleomenes was altogether encouraged, and his men, elated by their victory, betook themselves to supper; but Antigonus was dejected, since he was shut up by necessity to difficult plans.
For he was planning to march off to the promontory of the Heraeum, and from there to put his army across to Sicyon in transports—an undertaking requiring much time and extraordinary preparations. But when it was already towards evening, there came to him from Argos by sea some friends of Aratus, who summoned him to the city, on the ground that the Argives were ready to revolt from Cleomenes. The author of the revolt was Aristotle; and the multitude were easy to persuade, being incensed because Cleomenes had not brought about the abolition of debts which they expected.
