Around Berkshire, Herne is depicted wearing the antlers of a great stag. He is the god of the wild hunt, of the game in the forest. Herne's antlers connect him to the deer, which was given a position of great honor -- after all, killing a single stag could mean the difference between survival and starvation, so this was a powerful thing indeed.
Herne was considered a divine hunter, and was seen on his wild hunts carrying a great horn and a wooden bow, riding a mighty black horse and accompanied by a pack of baying hounds. Mortals who get in the way of the Wild Hunt are swept up in it, and often taken away by Herne, destined to ride with him for eternity. He's seen as a harbinger of bad omen, especially to the royal family. According to local legend, Herne only appears in Windsor Forest when needed, such as in times of national crisis.
