The coming of Christianity to the state of Kievan Rus' at the end of the tenth century had an enormous impact on the development of Russian civilization. Despite the abandonment of the pagan gods, both Christian and pagan practices and beliefs continued to coexist for centuries, producing a system known as "dual faith."
Russian Myths deals with mythic beliefs, notions, and customs—concerning the veneration of earth, water, fire, and air, demons and spirit-beings in the world of nature, the cult of the dead, and witchcraft—many of which have their roots in the pre-Christian past but still survive to the present day. To illuminate the evolution of major themes and motifs and set Russian myths in the context of mythology the world over, Elizabeth Warner draws upon a rich variety of sources, including anecdotal narrative forms and religious legends, epic songs, funeral laments and folk religion, and, of course, the folktales where the sacred gives way to pure imagination in the depiction of mythic themes and characters.
