The Greenman is a motif that is found in Europe, Britain, Africa and Asia. Often it is depicted in medieval churches carved into the wood work or masonry. It is a masculine face with leaves sprouting from the eyes, nose and mouth of the face. Jack in the Green is another name for him. It represents the strength of nature and its regenerative properties.
Connotations to nature are obvious with the Greenman; he may also be the signature of the mason or woodcarver who wanted to put their own face into the art.
