The Tie-Snake, estakwvnayv, is a water spirit of Muscogee (Creek) and broader Southeastern Indian tradition. Outwardly resembling an ordinary black or dark-blue snake, it is held to be enormously strong, seizing and binding people and game and pulling them beneath the surface of rivers and deep pools to drown; one account credits a Tie-Snake with raising a flood that overwhelmed a whole town. The Creek informant Jackson Lewis told John R. Swanton that the creature does not harm human beings but exerts a magnetic, drawing power over game. The Tie-Snake stands as the near double of the great Horned Serpent, the two being sometimes treated as a single being and sometimes distinguished, with the Horned Serpent reckoned the larger.
