Front and back views of an Altai Turk shaman drum. The image of the World Tree/Mother Spirit dominates both sides, bringing together the worlds. The plainer interior side has sun and moon images, rainbows on the left and right sides, what appears to be a turge tree, and dragons or snakes representing the lus water spirits. The outside shows a shaman holding a drum with a similar design, a horse tied to a turge, mountain goats, and a zukheli, the hide of a sacrificial animal hung on a tree. There appear to be two turtles in the upper world--the turtle is associated with the creation story. This drum is interesting in that the inner, secret, side shows the tree in a stylized human form, but on the front it appears as a stream or line uniting the worlds, representing the gol, center of all things.
