History of the Peloponnesian War

Also there happened at Peparethus a certain rising of the water, but it brake not in; and a part of the wall, the town-house, and some few houses besides were overthrown by the earthquakes.

The cause of such inundation, for my part, I take to be this: that the earthquake, where it was very great, did there send off the sea; and the sea returning on a sudden, caused the water to come on with greater violence. And it seemeth unto me that without an earthquake such an accident could never happen.
