The dictionary “Slavic Antiquities” is the first attempt in Slavic studies to create an ethnolinguistic dictionary of the traditional spiritual culture of all Slavic peoples. It sums up more than a century and a half of studying Slavic languages, folklore, mythology, ethnography, and folk art. Representing primarily scientific interest, this work, at the same time, is a fascinating read for a wide range of readers. The dictionary tells about different aspects of the spiritual life of the Slavic peoples. Special articles are devoted to folk ideas about the world order, nature, patron saints, beliefs about sorcerers, evil spirits, and various spirits. The dictionary details the folk calendar, rituals, customs, holidays and family life of the Slavs.
