Vodyanoy

Vodyanoy by Ivan Bilibin, 1934

In Slavic mythology, vodyanoy (Russian: водяной, IPA: [vədʲɪˈnoj]; lit. '[he] from the water' or 'watery') is a water spirit. In Czech and Slovak fairy tales, he is called vodník (or in Germanized form: Hastrman), and he is considered to be the equivalent creature as the Wassermann or nix of German fairy tales. In Ukrainian fairy tales, he is called “водяник“ (vodyanyk).

He may appear to be a naked man with a pot belly and (or bald-headed and wearing hat and belt of reeds and rushes, conflicting with other accounts ascribing him green hair and a long green beard. The varying look has been attributed by some to his shape-shifting ability. When angered, the vodyanoy breaks dams, washes down water mills, and drowns people and animals. Consequently, fishermen, millers, and also bee-keepers make sacrifices to appease him. The vodyanoy would sometimes drag people down to his underwater dwelling to serve him as slaves.
