The tree forms a vertical axis which organises the relationship between the earth and the heavens. It represents both the tree of life and the point of contact between heaven and earth, important elements in European and non-European cosmogonies.
It is related to the tree of paradise, the tree of the Kaballa, to the ash tree of Iggdrasil found in Germanic and Scandinavian mythology, to the Irminsul of the Saxons, to the Chinese “Kien-Mou” tree (a vertical pathway inhabited by spirits, souls and gods), and to the tree of the Shamans.
