In Greek mythology, the Sirens were dangerous yet beautiful creatures, portrayed as femme fatales who lured nearby sailors with their enchanting music and voices to shipwreck on the rocky coast of their island. Roman poets placed them on some small islands called Sirenum scopuli. In some later, rationalised traditions, the literal geography of the "flowery" island of Anthemoessa, or Anthemusa, is fixed: sometimes on Cape Pelorum and at others in the islands known as the Sirenuse, near Paestum, or in Capreae. All such locations were surrounded by cliffs and rocks.
When the Sirens were given a name of their own, they were considered the daughters of the river god Achelous, fathered upon Terpsichore, Melpomene, Sterope, or Chthon. Although they lured mariners, the Greeks portrayed the Sirens in their "meadow starred with flowers" and not as sea deities. Roman writers linked the Sirens more closely to the sea, as daughters of Phorcys. Sirens are found in many Greek stories, particularly in Homer's Odyssey.
