The Histories · 9.75

There was another illustrious deed done too by Sophanes; for when the Athenians besieged Egina he challenged to a fight and slew Eurybates the Argive, one who had been victor in the five contests at the games. To Sophanes himself it happened after these events that when he was general of the Athenians together with Leagros the son of Glaucon, he was slain after proving himself a good man by the Edonians at Daton, fighting for the gold mines.
