Trees are significant in many of the world's
mythologies and
religions, and have been given deep and sacred meanings throughout the ages. Human beings, observing the growth and death of
trees, and the annual death and revival of their foliage, have often seen them as powerful symbols of growth, death and rebirth. Evergreen trees, which largely stay green throughout these cycles, are sometimes considered symbols of the eternal,
immortality or
fertility. The image of the
Tree of life or
world tree occurs in many mythologies.
