Bulls. Big, strong, temperamental creatures that have had loomed large in man’s past. Bull jumping, bull baiting, bull fights and running of the bulls are events where they were, and in some cases still are, featured. They were used in the form of oxen to pull plows and carts. Their virility kept up herds, generating wealth for their owners. In some areas, placing a bull head above a door gives protection and luck much like the horse shoe. As sacrifices, few animals were more costly. From them we get the terms ‘seeing red’ and ‘bull-headed’. A lot of myths feature bulls, even modern myths like Paul Bunyan and his blue ox. In some cultures, earthquakes are blamed on a rowdy celestial bull believed to have the world upon its horns. A lot of masculine divinities, particularly those of the sun and the sky, are associated with bulls.
