SCYTHIAN GODDESS
Goddesses from Scythia, along the Black Sea coast, were often shown with the wings and tail of a bird. As such, they may have been the origin of the Sirin figures. In some cases they were used as standards carried at the head of armies in battle. They are thus related to the 'winged victories' found later in Greece.
The image is taken from a gold pendant in the Scythian gold collection at the Kiev Pechersky Lavra in Kiev, Ukraine. Fourth century BCE. It is pictured in Ganina.
