Although witchcraft evolved into an essentially Western phenomenon, its origin goes as far back into history as the written word, and earlier, and by one name or another, it appeared on every continent. But it only reached its prime during the rather lengthy period of flux in Europe when Christianity went bloodily and zealously to work stamping out paganism. That was when witches became most numerous, and it was also the period for witches and witchcraft to become stereotyped. Witches have changed very little since those days, and are only slightly less numerous in the twentieth century than they presumably were in the fifteenth century. The number of people who depend upon witchcraft in the twentieth century is also only slightly diminished.
