Sirens are from Greek mythology. In the story of Odysseus, the Sirens are beautiful women who lure sailors with their voices. Odysseus escaped the Sirens by having all his sailors plug their ears with beeswax. He was curious as to what the Sirens sounded like, so he let himself be tied to the mast to ensure he could not fall victim to their voices.
