The Green Man is repeatedly perceived as an antique Celtic symbol. In Celtic mythology, he is a god of movement and summer. He disappears and returns day gone year, century subsequent to century, enacting themes of bereavement and resurrection, the ebb and stream of verve and creativity. The Arthurian legend of Sir Gawain, The Green Knight, is a notable likeness of the Green Man from the middle Ages. Gawain had a green helmet, green armor, grreen shield... uniform a green horse. As he was decapitated, he continued to live.
