A wonderful image of Herne the Hunter appearing to the Earl of Surrey deep in the forest

"The Earl of Surrey was suddenly startled by the brightness of a blue phosphoric light, streaming through the bushes into the blackness around him. the light revealed at the foot of an enormous oak tree, with snake-like protruding roots, a wild, spectral-looking object suggesting both man and beast in appearance. the spectre seemed to be clothed in the skins of deer, which were hung about his gaunt and tawny-coloured limbs in an odd fashion. His helmet was the skull of a stag, from which branched a large pair of antlers. Hanging from his left arm was a heavy, rusty-looking chain, and in its links burnt the blue fire. the right wrist was perch for a large-horned owl, with red forbidding eyes, and feather stranding erect."

In English folklore, Herne the Hunter is an equestrian ghost associated with Windsor Forest and Great Park in the English county of Berkshire. His appearance is notable in the fact that he has antlers upon his head.
Herne is said to have been a huntsman in the employ of King Richard II (reigned 1377–1399) in and around Windsor Forest. He saved the King's life when he was attacked by a cornered white hart, but was mortally wounded himself in the process. A local wizard brought him back to health using his magical powers, which entailed tying the dead animal's antlers on Herne's head. In return, however, Herne had to give up his hunting skills. The king's other huntsmen framed him as a thief. As a result he lost the favour of the king. He was found the next day, hanging dead from a lone oak tree. That same oak tree is in the Home Park at Windsor Castle. (Wikipedia)
