World tree
Videos
The world tree is a motif present in several religions and mythologies, particularly Indo-European, Siberian, and Native American religions. The world tree is represented as a colossal tree which supports the heavens, thereby connecting the heavens, the terrestrial world, and, through its roots, the underworld. It may also be strongly connected to the motif of the tree of life, but it is the source of wisdom of the ages.
