It is common for some sign to be given when great ills threaten cities or nations; for before all this plain signs had been sent to the Chians. [2] Of a band of a hundred youths whom they had sent to Delphi only two returned, ninety-eight being caught and carried off by pestilence; moreover, at about this same time, a little before the sea-fight, the roof fell in on boys learning their letters: of one hundred and twenty of them one alone escaped. [3] These signs a god showed to them; then the sea-fight broke upon them and beat the city to its knees; on top of the sea-fight came Histiaeus and the Lesbians. Since the Chians were in such a bad state, he easily subdued them.
