Agis and Cleomenes
Plutarch
Plutarch. Plutarch's Lives, Vol. X. Perrin, Bernadotte, translator. Cambridge, MA: Harvard University Press; London: William Heinemann Ltd., 1921.
The Corinthians were so eager to get to Cleomenes at Argos that, as Aratus says, all their horses were ruined. Aratus says also that Cleomenes upbraided the Corinthians for not seizing him, but letting him escape; however, Megistonoüs came to him, he says, bringing from Cleomenes a request for the surrender of Acrocorinthus (which was held by an Achaean garrison) and an offer of a large sum of money for it; to which he replied that he did not control affairs, but rather affairs controlled him. This is what Aratus writes.
But Cleomenes, marching up from Argos and taking over Troezen, Epidaurus, and Hermioné, came to Corinth. Its citadel he blockaded, since the Achaeans would not abandon it, and after summoning the friends and stewards of Aratus, ordered them to take the house and property of Aratus into their charge and management.
