History of the Peloponnesian War

The same summer, the Athenians put the Aeginetae, man, woman, and child, out of Aegina, laying to their charge that they were the principal cause of the present war. And it was also thought the safer course to hold Aegina, being adjacent to Peloponnesus, with a colony of their own people; and not long after they sent inhabitants into the same.

When the Aeginetae were thus banished, the Lacedaemonians gave them Thyrea to dwell in and the occupation of the lands belonging unto it to live on, both upon hatred to the Athenians, and for the benefits received at the hands of the Aeginetae in the time of the earthquake and insurrection of the Helotes. This territory of Thyrea is in the border between Argolica and Laconica, and reacheth to the seaside. So some of them were placed there, and the rest dispersed into other parts of Greece.
