Having done a little on-line research, I've discovered that there's quite a lot of material relating to the legend of Herne. This from Wikipedia:
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 other king's 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.
- Sometime a keeper here in Windsor Forest,
- Doth all the winter-time, at still midnight,
- Walk round about an oak, with great ragg'd horns;
- And there he blasts the tree, and takes the cattle,
- And makes milch-kine yield blood, and shakes a chain
- In a most hideous and dreadful manner.
- You have heard of such a spirit, and well you know
- The superstitious idle-headed eld
- Receiv'd, and did deliver to our age,
- This tale of Herne the Hunter for a truth.
- — William Shakespeare, The Merry Wives of Windsor
