Woodcut of a "Triton and a Siren, seen on the Nile" from Des Monstres et prodiges by Ambroise Par矇, 1573. Des Monstres is filled with unsubstantiated accounts of sea devils, marine sows, and monstrous animals with human faces. With its extensive discussion of reproduction and illustrations of birth defects, the book invited accusations of pornography. Triton is a mythological Greek god, the messenger of the sea. He is the son of Poseidon and Amphitrite, god and goddess of the sea respectively, and is herald for his father. He is usually represented as a merman, having the upper body of a human and the tail of a fish. In Greek mythology the Sirens were dangerous and beautiful creatures, portrayed as femme fatales who lured nearby sailors with their enchanting music and voices to shipwreck on the rocky coast of their island. They were formerly handmaidens of the goddess Persephone. When the girl was secretly abducted by Hades, Demeter gave them the bodies of birds, and sent to assist in the search. They eventually gave up and settled on the flowery island of Anthemoessa. The Sirens were later encountered by the Argonauts who passed by unharmed with the help of Orpheus, the poet drowning out their music with his song. Odysseus also sailed by, bound tightly to the mast, his men blocking their ears with wax. The Sirens were so distressed to see a man hear their song and yet escape, that they threw themselves into the sea and drowned.
