The Green Man represents man in nature and as such makes a good symbol of the human aspect of rewilding. It has appeared on churches for hundreds of years but was only given a name in Lady Raglan’s Folklore Journal paper in 1939. People have since made wider connections to Jack-in-the-Green of Morris dancing and May Day festivals, the Celtic horned god Cernunnos, Herne the Hunter, and even Robin Hood. So it is both old and relatively new as a concept. Which also applies to the Green Man Festival in Clun.
I can’t remember when I first became aware of the Green Man – a figure of a human face made of or surrounded by leaves. I think my parents pointed them out in the 1980s, along with the similarity between fan-vaulted church ceilings (like Kings College Chapel) and the canopy of trees in the forest. They both seem to be medieval attempts to bring the wild wood that everyone knew into the sacred space of the church. For me, the Green Man is sometimes a personification of nature, but sometimes he is a symbol of mankind as part of nature and that’s another way of representing the idea of rewilding ourselves.
