Plutarch, Quaestiones Graecae
Frank Cole Babbitt, Ed.

Cothus and Aeolus, the sons of Xuthus, carne to Euboea to dwell at a time when the Aeolians possessed the greater part of the island. It had been prophesied to Cothus that he should have great success and get the better of his enemies if he bought the land. When he had landed on the island with a few men, he encountered little children playing by the sea. So he joined in their play, and in a kindly spirit showed them many playthings [p. 205] from foreign lands. But when he saw that the children were desirous of having them for their own, he refused to give them unless he too should receive some earth from the children. So they picked up some from the ground and gave it to Cothus, and then, taking the playthings, departed. But the Aeolians discovered what had happened, arid, when their enemies sailed against them, they made away with the children under stress of anger and grief. The children were buried beside the road which leads from the city to the Euripus, and the place is called the Children's Tomb.
