Histories

It was for giving this answer and refusing to give what was asked of them that they were besieged. There was no end to Themistocles' avarice; using the same agents whom he had used with the king, he sent threatening messages to the other islands, demanding money and saying that if they would not give what he asked he would bring the Greek armada upon them and besiege and take their islands.

Thereby he collected great sums from the Carystians and Parians, for these were informed that +Andros [24.9,37.816] (inhabited place), Nisos Andros, Cyclades, Aegean Islands, Greece, Europe Andros was besieged for taking the Persian side and that Themistocles was of all the generals the most esteemed. This frightened them so much that they sent money. I suppose that there were other islanders too who gave and not these alone, but I cannot with certainty say.
