Baba Yaga is the old woman of autumn, the archetype of the fearsome witch. Her roots lie in the ancient Slavic goddess of death and birth, whose wheat sheaves in the autumn fields hold the promise of winter survival and spring's growth. Baba Yaga flies through the air in a mortar, rowing with a pestle, or in a cauldron, sweeping the traces of her path with a broom. In some tales, she is the guardian of the fountain of the waters of life; in other tales, she lives in a hut surrounded by a fence of bones. In all cases, she is a crone, hideous to look upon, and much to be feared. Her realm is the birch forests, birch being the tree of beginnings and endings. Baba Yaga represents the power of old age, the power of the archetype of witch, and most of all, the power of the cycles of life, death and rebirth.
