Some etymological theories suggest this figure of speech probably draws on the visual imagery of the Minoan-Mycenaean civilization (i.e. the Mediterranean Bronze Age civilization that developed on the island of Crete and continental Greece from 2700 to 1450 BC). Bull leaping (or tauromachy) was a very popular sport all over the Greek lands back then. During this highly dramatic act, an acrobat, who was usually a religious figure as well, would dart towards a fast-approaching bull. By grabbing the animal by the horns, the athlete was then able to perform a somersault and fly all over the bull’s back.
