Огненный ангел
Valery Bryusov's novel "The Fiery Angel" is also well known. It tells the story of a 16th-century German scholar and his attempts to win the love of a young woman whose spiritual integrity is seriously undermined by her participation in occult practices and her dealings with unclean forces. The novel served as the basis for Sergei Prokofiev's opera "The Fiery Angel".
