In Russian and Eastern European folklore, Baba Yaga is described and pictured as flying through the forest standing inside a large wooden mortar (stupa), holding the long wooden pestle in one hand to remove obstacles in front of her, and using the broom in her other hand to sweep and remove her traces behind her. This seems as a trace of some ancient rituals connecting the witch symbols of Baba Yaga with the use of mortars in alchemy, pharmacy and early chemistry, which was all seen as magic by uneducated people in Medieval Ages.
