History of the Peloponnesian War

The Athenians afterwards sent back Artaphernes in a trireme to Ephesus, and ambassadors with him; but on hearing there that king Artaxerxes, son of Xerxes, was lately dead, (for it was at that time that he died,) they returned home.

The same winter also the Chians dismantled their new fortifications, at the command of the Athenians, and in consequence of their suspecting that they would form some new designs against them: they obtained, however, pledges from the Athenians, and security (as far as they could) for their making no change in their treatment of them. And so the winter ended and the seventh year of this war, of which Thucydides wrote the history.

At the very commencement of the following summer, there was an eclipse of the sun at the time of a new moon, and in the early part of the same month an earthquake.
