was lifted out of its dock and thrown over a city wall. Thucydides gave the following account, noting the characteristic sequence of quake, receding water and huge wave:
About the same time that these earthquakes were so common, the sea at Orobiae, in Euboea, retiring from the then line of coast, returned in a huge wave and invaded a great part of the town, and retreated leaving some of it still under water; so that what was once land is now sea; such of the inhabitants perishing as could not run up to the higher ground in time. A similar inundation also occurred at Atalanta, the island off the Opuntian-Locrian coast, carrying away part of the Athenian fort and wrecking one of two ships which were drawn up on the beach. At Peparethus also the sea retreated a little, without however any inundation following; and an earthquake threw down part of the wall, the town hall, and a few other buildings. ... The cause, in my opinion, of this phenomenon must be sought in the earthquake. At the point where its shock has been the most violent the sea is driven back, and suddenly recoiling with redoubled force, causes the inundation. Without an earthquake I do not see how such an accident could happen.
