They were first employed as a choral team by PERSEPHONE but didn’t offer any assistance when HADES came and abducted her. No protest songs, no banners, nothing. DEMETER, mum of PERSEPHONE, thought they were most disloyal, and changed them into birds with women’s heads and lion claws, banishing them to a remote barren island.
When a rare ship is sighted, they sing their hearts out hoping that DEMETER will hear them and take pity. She never does, and when the sailors draw nearer to listen, and the first sailor says "I don’t fancy your bird" or "Look at the claws on that", the SIRENS forget any semblance of maidenly manners. With them the phrase ‘going for a song’ takes on a new meaning of unbridled savagery. Besides, they need to eat.
