History of the Peloponnesian War

the Athenians in the same summer made an expedition with sixty ships, two thousand heavy infantry, a few cavalry, and some allied troops from Miletus and other parts, against Cythera, under the command of Nicias, son of Niceratus, Nicostratus, son of Diotrephes, and Autocles, son of Tolmaeus.

Cythera is an island lying off Laconia, opposite Malea; the inhabitants are Lacedaemonians of the class of the Perioeci; and an officer called the Judge of Cythera went over to the place annually from Sparta. A garrison of heavy infantry was also regularly sent there, and great attention paid to the island,

as it was the landing-place for the merchantmen from Egypt and Libya, and at the same time secured Laconia from the attacks of privateers from the sea, at the only point where it is assailable, as the whole coast rises abruptly towards the Sicilian and Cretan seas.
