Nepalese Copper Lakhe Festival Mask; Nepalese Copper Lakhe Festival Mask, ca. 19th Century AD. Originally Lakhe or Lakey was a forest demon in Newar folklore of the Kathmandu Valley in Nepal. He was converted from his former nasty ways by villagers and put to good. He became a popular and playful protector of the Newar – a good demon working on the inside to ward away those demons still bad. The mask is made of copper repousse. It now has a green patina on much of its surface. Such masks were painted bright red with black and white detailing and black bear or yak fur was sewn around the edges. D.10 1/2" (26.7 cm)..
