The Cyclopean Isles (Italian: Isole Ciclopi), noted for their rows of basaltic columns piled one above another, lie not far from Mount Etna off the eastern coast of Sicily in the Mediterranean Sea.
Formed about 500,000 years ago, the Cyclopean Isles are of volcanic origin and may at one time have been attached to Sicily.

There is an ancient tradition that the islands at one time formed part of the mainland of Sicily.

Homer (Alexander Pope's translation) says:
Odysseus boasts that it was "Odysseus... Son of Laertes" who had burnt out Polyphemus's eye. Polyphemus invokes the vengeance of his father Poseidon, and:
