Tree of Life has been inspired by ancient Celtic Mythology and the importance of nature in early Irish life. The Ancient Celts depended on the trees for their day-to-day existence as they provided a means of shelter, food, heat and even housed wildlife that was once hunted in Ireland. The Celts believed there was a connection between nature and the life beyond, the tree represented a connection between earth and the afterlife, mind and body and the never-ending cycle of life. It is thought they believed that trees held the spirits of their ancestors. The Oak was seen as a towering symbol of nobility, strength, endurance, longevity and wisdom.
