Unlike the well-established religions of Greece, Rome and Egypt, Celtic myth is more localized, with no universal pantheon. References have been found to over 400 Celtic gods and goddesses, many of whom were only recognized by small cults.
At one time, the Celtic people were spread throughout Europe as far as Asia minor. The Celts even occupied Rome for a time, before the rise of the Roman Empire, and although they were eventually brought into the Roman Empire, the Celtic people continued to worship their own religions until Christianity took hold of Rome. Today, those of Celtic descent live mostly in the area of Britain, Sclotland and Ireland.
