Sirin is a mythological creature of Russian legends, with the head and chest of a beautiful woman and the body of a bird. According to myth, the Sirins lived "in Indian lands" near Eden or around the Euphrates River. These half-women half-birds are directly based on the Greek myths and later folklore about sirens. Sirins sang beautiful songs to the saints, foretelling future joys. For mortals, however, the birds were dangerous. Men who heard them would forget everything on earth, follow them, and ultimately die.
