Snegurochka

Snegurochka (rus. Снегурочка, derived from "Snow Maiden", also known as Snegurka, Snezjevichka) — one of the most well-known characters from russian folklore, a girl, made from snow. It is likely that the image of Snegurochka was originally associated with the seasons cycle and the processes of nature's death/resurrection (analogically with Kupala and Kostroma), but later the character has transformed from mythological to entirely folkloristic. According to the story, Snezjevichka was made as a snowman and then animated and transformed into a real living girl. She doesn't lose any properties of snow, though, therefore any heat, fire, or even sunlight (in some variations) are fatal to Snegurochka.
