Aeschines in the [speech] On the malconducted embassy [sc. mentions this].[1] Aristotle explains in Athenaion Politeia what a campaign in the eponyms was;[2] "there are", he says, "ten eponymous heroes of the tribes and forty-two of the age-groups.[3] Formerly the [sc. names of the] ephebes who were being enrolled were inscribed on whitened tablets, and above their names were written those of the archon in whose year they were enrolled and the eponymous hero who was in residence in the previous year.[4] Now, however, they are inscribed before the boule."[5] And a little later [he says] [6]: "they use the eponymous heroes also for campaigns. When they send out an age-group they indicate who is to serve by writing the names of the eponymous archons[7] of the youngest and oldest age-groups being called up."
