Arash the Archer (Persian: آرش کمانگیر Āraš-e Kamāngīr) is a heroic archer-figure of Iranian mythology. According to Iranian folklore, the boundary between Iran and Turan was set by an arrow launched by Arash, after he put his own life in the arrow's launch. The arrow was traveling for days before finally landing on the other side of the Oxus on the bark of a walnut tree hundreds of miles away from the original launch site atop a mountain.
