The Green Man is a recurring figure in many old churches and buildings throughout Europe. He is recognizable as a face in foliage, usually with vines growing into the mouth and sometimes eyes or nostrils. There are many who have adopted the Green Man as a Pagan symbol, but his true meaning was lost sometime during the Middle Ages. The Green Man is a very mysterious figure, a fact that is quite startling given his ubiquitous nature.
The Green Man pictured is from Rosslyn Chapel. He also shows up at the Glasgow Cathedral, which I hope to visit soon. I'll be sure to post pictures whenever he crops up on my travels!
