History of the Peloponnesian War

Contrariwise, the Athenians required the Lacedaemonians to banish such as were guilty of breach of sanctuary at Taenarus. For the Lacedaemonians, when they had caused their Helots, suppliants in the temple of Neptune at Taenarus, to forsake sanctuary, slew them: for which cause they themselves think it was that the great earthquake happened afterwards at Sparta.

Also they required them to purge their city of the pollution of sanctuary in the temple of Pallas Chalcioeca, which was thus.

After that Pausanias the Lacedaemonian was recalled by the Spartans from his charge in Hellespont, and having been called in question by them was absolved though he was no more sent abroad by the state, yet he went again into Hellespont in a galley of Hermione as a private man, without leave of the Lacedaemonians, to the Grecian war, as he gave out, but in truth to negotiate with the king, as he had before begun, aspiring to the principality of Greece.
