Pelopidas (20.4-21.1)

At the commission of such a grievous and lawless act, their father, since he could get no justice at Sparta, heaped curses upon the Spartans, and then slew himself upon the tombs of the maidens; and ever after, prophecies and oracles kept warning the Spartans to be on watchful guard against the Leuctrian wrath. Most of them, however, did not fully understand the matter, but were in doubt about the place, since in Laconia there is a little town near the sea which is called Leuctra, and near Megalopolis in Arcadia there is a place of the same name. This calamity, of course, occurred long before the battle of Leuctra.

After Pelopidas had lain down to sleep in the camp, he thought he saw these maidens weeping at their tombs, as they invoked curses upon the Spartans, and Scedasus bidding him sacrifice to his daughters a virgin with auburn hair, if he wished to win the victory over his enemies. The injunction seemed a lawless and dreadful one to him, but he rose up and made it known to the seers and the commanders.
