A design generated in Gimp. My 10th design of the Celtic Tree of Life. It is known that the concept of a ‘Tree of Life’ has been used in religion and other beliefs, as a mystical concept of all life on our planet; and a metaphor for common descent in the evolutionary sense. A tree-worshiping culture arose in Indonesia and was diffused by the so-called “Younger Dryas” event of c. 8000 BCE, when the sea-level rose. It then spread throughout Europe and included the Celts.
