Aratus (25.2-25.3)

Accordingly, men were found to dare the deed, of whom Aeschylus and Charimenes the seer were the chief. They had no swords, however, the tyrant having prohibited the possession of them under heavy penalties. Aratus, therefore, ordered small daggers to be made for them in Corinth and sewed them up in pack-saddles; these he put upon beasts of burden carrying ordinary wares and sent them into Argos.

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.
