n think of the Salem witchcraft as a kind of fire which, once started, could not be quenched until it had burned itself out.By this analogy, the big logs would be the belief in witchcraft itself. This belief was an old one. In the ancient world, sorcery was everywhere--in Egypt and Babylon, even among the clear-thinking Greeks and the otherwise sensible Romans. Only the Jews, among all these ancient peoples, had laws forbidding the practice of witchcraft. It is first mentioned in the Old Testament (Exodus 22:18), where it says, "Thou shalt not suffer a witch to live." It was on the authority of this one sentence in the Bible that the 19 witches were hanged in Salem in 1692.But until the end of the Middle Ages, no one had made a "scientific" study of the spirit world, and ideas about witches varied wildly from place to place and century to century. Then in 1486 two Christian monks brought out a book called the Malleus Maleficarum (The Hammer of Witches), the first book of demonology. Others soon followed (King James I of England even wrote one himself), and by the time Reverend Hale walked into Salem in 1692 with an armload of such books, the study of witchcraft was considered an exact science. When he says of his books, "Here is all the invisible world, caught, defined, and calculated," he is being sincere. He has studied these books for years and he honestly believes himself to be an expert. So does everyone else. There is no reason to doubt him or his ability to deal with an enemy he knows so much about. Without this solid and specific belief in the reality of witchcraft, there might have been only a little brushfire in Salem.The kindling of the fire was to be found in the visible world. In 1623 King James I (the same one who wrote the demonology book) had granted a charter to the Massachusetts Bay Colony, under which the Puritans could own their own land. This charter enabled the colony to thrive and grow over the next 60 years. But ...
