Sirens

Odysseus and the Sirens.

In Ancient Greek mythology, the Sirens (Greek singular: Σειρήν Seirēn; Greek plural: Σειρῆνες Seirēnes) were dangerous female creatures, portrayed by Homer and other authors as seductresses who lured nearby sailors with their enchanting music and voices to shipwreck on the rocky coast of an island, possibly Sicily. Sirens combine women and birds in various ways. In early Greek art Sirens were represented as birds with large women's heads, bird feathers and scaly feet. Later, they were represented as female figures with the legs of birds, with or without wings, playing a variety of musical instruments, especially harps. European Renaissance artwork often depicts them as fish-women or mermaids, possibly due to a mistranslation.

Sirens in "The Horse of Bronze"

Sirens were bird like creatures with heads like Centaurs, who inhabited the isle of Sicily, and preyed on all those who set foot on their lands. All sirens were she's which led Cheiron to often wonder how new sirens were born if there were no he's to breed with.

While hunting for meat, Cheiron and his party encountered a Siren who tried to seduce them. Unfortunately having too many targets at once prevented the Siren from completely entrancing all three Centaurs and they broke free from her spell, killing her. This angered the other Sirens who chased Cheiron and his crew along the coast. After trying to fool the Sirens into thinking they were sailing away, Cheiron and his men came ashore and night to collect fresh water only to be attacked by the Sirens.

Cheiron quickly deduced that by shouting as loud as they could, all the Centaurs could drown out the signing. This plan worked and they all managed to escape, even killing a few Sirens as they did so.
