In one of the tombs, then, were the “irens,” in the second the rest of the Spartans, and in the third the helots. This, then is how the Lacedaemonians buried their dead. The Tegeans, however, buried all theirs together in a place apart, and the Athenians did similarly with their own dead. So too did the Megarians and Phliasians with those who had been killed by the horsemen.
All the tombs of these peoples were filled with dead; but as for the rest of the states whose tombs are to be seen at +Plataea (inhabited place), Boeotia, Central Greece and Euboea, Greece, Europe Plataeae, their tombs are but empty barrows that they built for the sake of men that should come after, because they were ashamed to have been absent from the battle. There is one there called the tomb of the Aeginetans, which, as I learn by inquiry, was built as late as ten years after, at the Aeginetans' desire, by their patron and protector Cleades son of Autodicus, a Plataean.
As soon as the Greeks had buried their dead at Plataea [23.2667,38.2] (Perseus) Plataea, they resolved in council that they would march against Thebes [23.3333,38.325] (Perseus) Thebes and demand surrender of those who had taken the Persian side—particularly of Timagenidas and Attaginus, who were chief among their foremost men. If these men were not delivered to them, they would not withdraw from the area in front of the city till they had taken it.
