The Eratosthenes Seamount or Eratosthenes Tablemount is a seamount in the Eastern Mediterranean, in the Levantine basin about 100 kilometres (60 mi) south of western Cyprus.

[3] It is a large, submerged massif, about 120 by 80 kilometres (75 by 50 mi).

[4] It is one of the largest features on the Eastern Mediterranean seafloor.

Such seamounts are considered to be ideal for the preservation of shipwrecks because at depths of around 600 metres (2,000 ft) the areas are not disturbed by trawlers or by sediments coming off land.

[6] During the Messinian crisis, as the sea level in the Mediterranean dropped by about 1,500 metres (4,900 ft), the seamount emerged.
