RAHU

In Hindu mythology, Rahu is the demon that causes eclipses. The story says that he drank some of the nectar of immortality, was caught by the sun and moon who informed upon him and Vishnu cut off his head, however the mouth having touched the elixir remained immortal and forever hunts the sun and moon, occasionally catching them and so causing eclipses.
