Cotton, minister of the First Church at Boston, entitled _The Bloody Tenent Washed and made White in the Blood of the Lamb_. Williams was also a friend to the Indians, whose lands, he thought, should not be taken from them without payment, and he anticipated Eliot by writing, in 1643, a _Key into the Language of America_. Although at odds with the theology of Massachusetts Bay, Williams remained in correspondence with Winthrop and others in Boston, by whom he was highly esteemed. He visited England in 1643 and 1652, and made the acquaintance of John Milton. Besides the threat of an Indian war and their anxious concern for the purity of the Gospel in their churches, the colonists were haunted by superstitious forebodings of the darkest kind. It seemed to them that Satan, angered by the setting up of the kingdom of the saints in America, had "come down in great wrath," and was present among them, sometimes even in visible shape, to terrify and tempt. Special providences and unusual phenomena, like earth quakes, mirages, and the northern lights, are gravely recorded by Winthrop and Mather and others as portents of supernatural persecutions. Thus Mrs. Anne Hutchinson, the celebrated leader of the Familists, having, according to rumor, been delivered of a monstrous birth, the Rev. John Cotton, in open assembly, at Boston, upon a lecture day, "thereupon gathered that it might signify her error in denying inherent righteousness." "There will be an unusual range of the devil among us," wrote Mather, "a little before the second coming of our Lord. The evening wolves will be much abroad when we are near the evening of the world." This belief culminated in the horrible witchcraft delusion at Salem in 1692, that "spectral puppet play," which, beginning with the malicious pranks of a few children who accused certain uncanny old women and other persons of mean condition and suspected lives of having tormented them with magic, gradually drew into its vortex victims of the highest character, and resulted in the judicial murder of over nineteen people. Many of the possessed pretended to have been visited by the apparition of a little black man, who urged them to inscribe their names in a red book which he carried--a sort of muster-roll of those who had forsworn God's service for the devil's. Others testified to having been present at meetings of witches in the forest. It is difficult now to read without contempt the "evidence" which grave justices and learned divines considered sufficient to condemn to death men and women of unblemished lives. It is true that the belief in witchcraft was general at that time all over the civilized world, and that sporadic cases of witch-burnings had occurred in different parts of America and Europe. Sir Thomas Browne, in his _Religio Medici_, 1635, affirmed his belief in witches, and pronounced those who doubted of them "a sort of atheist." But the superstition came to a head in the Salem trials and
