Can you give me a brief Early History of Hypnosis?

Hypnosis has been around since the dawn of recorded time, and at least to the time of the ancient Babylonians, Greeks and Egyptians. It was know to Hippocrates. Indeed, hypnosis is named after the Greek word for sleep, hypnos, although the actual state of hypnosis is very different from sleep. It has, however, been called different names, by different cultures, different religions, and different individuals. Such methods have been used successfully by the Druids, Vikings, Indian Yogis, Dervishes, Hindu priests, and holy men of all religions and denominations for centuries.
