Night on Bald Mountain 25 December 1858, has been interpreted as an indication of Mussorgsky's intent to write an opera on the subject of Gogol's short story "St. John's Eve" (, "Vecher nakanune Ivana Kupala", "St. John's Eve"). Gogol's tale contains the elements of witchcraft common to other stories in the "Evenings on a Farm near Dikanka" collection, but does not feature a witches' sabbath. No further plans for this project were mentioned. The theme of a witches' sabbath, the central theme in all subsequent "Night on Bald Mountain" projects, appears to have been derived from the nonextant play "The Witch" (, "Ved′ma") by
Night on Bald Mountain her father Mstivoy, the Prince of Retra, have poisoned Mlada, the betrothed of Yaromir, Prince of Arkona. Voyslava sells her soul to Morena, an evil goddess, to obtain her aid in making Yaromir forget Mlada so she may have him to herself. In act 3, the shade (ghost) of Mlada leads Yaromir up the slopes of Mount Triglav to a pine wood in a gorge on top of the mountain. Mlada's shade joins a gathering of the spirits of the dead. She expresses in mime to Yaromir the wish to be reunited with him in the kingdom of dead souls.
