Night on Bald Mountain1940

At Walpurgis Night (the Witches' Sabbath), Chernabog, God of evil, emerges from the peak of Bald Mountain (in reality Mount Triglav, in Slovenia) to summon all of his minions, including ghosts, vultures, demons, hags, and harpies, who dance furiously as he throws them into the mountain's fiery pit.
