2D Celtic Tree Printed in Basic Pla Black and White. The Celts depicted a tree in the form of hands stretching to the sky, and below they had the contours of roots. People have always believed in worldly life and a parallel world. This symbol meant the unity of the three worlds: underworld, life on earth, and in heaven.

According to the Celts, trees were considered to be ancient living things that played a very important role in their lives. With their roots firmly rooted in the earth and their branches reaching high in the sky, sacred trees connect us to the other world, spirits, and our ancestors.
