As you get closer to Positano on the Amalfi, The Sirenusas are an archipelago of little islands. The name, Sirenuse, is a reference to the mythological sirens said to have lived there as mentioned in the Iliad and the Odyssey.
Several sirens were said to have inhabited the islands, the most famous of whom were Parthenope, Leucosia, and Ligeia. One of them played the lyre, another sang, and another played the flute. They are mentioned in the 1st century BC by Strabo, the Greek Geographer and by Straton of Sardis in 120 A.D. In ancient stories, the sirens were depicted as having bodies of a bird and human heads, but the medieval interpretations of the stories depicted them as mermaids.
