Siren , in Greek mythology, one of three sea nymphs, usually
represented with the head of a woman and the body of a bird.
Daughters of Phorcus or of Achelous, the Sirens inhabited an island
surrounded by dangerous rocks. They sang so enchantingly that all
who heard were drawn near and shipwrecked. Jason and the Argonauts
were saved from them by the music of Orpheus, whose songs were
lovelier. Odysseus escaped them by having himself tied securely to
a mast and by stopping the ears of his men.
