Alan G. Hefner writes about the Green Man at Encyclopedia Mythica. "A legendary pagan deity who roams the woodlands of the British Isles and Europe. He usually is depicted as a horned man peering out of a mask of foliage, usually the sacred oak. He is known by other names such as "Green Jack, "Jack-in-the-Green" and "Green George." He represents spirits of trees, plants and foliage. It is believed he has rain making powers to foster livestock with lush meadows. He was frequently depicted in medieval art, including church decorations.." This example is based on a relief sculpture I found in Dore Abbey in Herefordshire a few years ago. I placed the image in my digital blender set to "chop" rather than the usual "puree".
