Vodyanoy — "the Water One," from the Russian voda — was the male water-spirit of Slavic folk tradition, who lived in lakes, rivers, and millponds, and who was the master of all the fish and water-creatures in his domain. He was depicted as an old man with a long beard of green water-weed, a body covered with scales or with leaves and slime, and bulging froglike eyes; he was paunchy from too much fish, and lived in an underwater palace where he kept the souls of those he had drowned as his servants.
Vodyanoy was the eternal danger for the rural community. Fishermen who failed to make the proper offerings to him risked losing their nets, having their boats overturned, or being drawn down themselves. Bathers who entered the water at noon or midnight, or on certain days unmarked by the village calendar, might be seized by him from below and never seen again. Drowning victims were said to have been taken by Vodyanoy to be his servants in the underwater palace.
He had wives — drowned women who became his consorts — and could rise from the water in their company on certain nights to dance upon the bank or to lure men into the water by the sight. The Vodyanoy could be propitiated by offerings (a black goat sacrificed and thrown into the water, butter and honey poured into the millpond, a portion of the day's catch returned to him), and the millers in particular maintained relations of careful exchange with him, for the working of the water-mills required his cooperation. The figure persisted in folk practice into the twentieth century in remote Russian villages, and was treated by Anton Chekhov in his short story "The Vodyanoy" and by Antonín Dvořák in his great tone-poem of 1896.
