In Russian fairy tales, the narrative flows a little differently. In those stories, you won’t find a tale for Cinderella, one for Snow White, one for Rapunzel. Instead, a peculiar cast of characters recurs over and over, in nearly every story, performing different acts and suffering different sorrows, but remaining the same. Ivan the Fool. Yelena the Bright. Baba Yaga. Vasilisa the Brave. Koschei the Deathless.
