Histories

Then Cleomenes' plan was this: He had with him some deserters from whom he learned the names, then he sent a herald calling by name the Argives that were shut up in the sacred precinct and inviting them to come out, saying that he had their ransom. (Among the Peloponnesians there is a fixed ransom of two minae to be paid for every prisoner.) So Cleomenes invited about fifty Argives to come out one after another and murdered them.
