Siren

In Greek mythology, sirens are female beings with alluring voices who lure sailors toward danger with their singing. They appear in the Odyssey, where Odysseus has his crew stop their ears with wax while he alone remains bound to the mast so he can hear the sirens' song and survive the encounter. Roman poets placed the sirens on a group of small islands called the Sirenum Scopuli. In their earliest Greek depictions the sirens were shown as part woman and part bird, a hybrid form later reinterpreted in some traditions as a fish-tailed mermaid.
