“A book fell from heaven. She was called the “dove” because of her purity and heavenly holiness. Or “deep” - from the depth of the wisdom contained in it. The book talked about how our world began: where the white light, the sun, the month, the stars, dawn, thunder, wind came from, where the classes came from - kings, prince-boyars, peasants. And about what is the most sacred and important thing in this world: which king is the king above kings, which land is the mother of all lands, which is the most important sea, lake, river, church, mountain, stone, tree, grass, animal, bird . And also about how Pravda fought with Krivda and where she, Pravda, went in this sinful world.” — This is how the “walking kaliki,” blind wanderers reciting spiritual poems, sang in Rus' from ancient times. We learn about the existence of this mysterious book from the life of the 13th-century scholar-priest Abraham of Smolensk. In the 1760s, “The Verse about the Dove Book” was recorded by one of the first collectors of Russian folklore, the legendary Kirsha Danilov. But only modern scientists have realized that the “Dove Book” is a cosmogonic myth of the ancient Slavs, consonant with the Indian “Rig Veda”, the Scandinavian “Elder Edda”, the Persian “Avesta” and the “Popol Vuh” of the American Indians.
