In the first place, I venture to say that it can admit of no doubt, that Increase Mather and his son, Cotton Mather, did more than any other persons to aggravate the tendency of that age to the result reached in the Witchcraft Delusion of 1692. The latter, in the beginning of the Sixth Book of the Magnalia Christi Americana, refers to an attempt made, about the year 1658, "among some divines of no little figure throughout England and Ireland, for the faithful registering of remarkable providences. But, alas," he says, "it came to nothing that was remarkable. The like holy design," he continues, "was, by the Reverend Increase Mather, proposed among the divines of New England, in the year 1681, at a general meeting of them; who thereupon desired him to begin and publish an Essay; which he did in a little while; but there-withal declared that he did it only as a specimen of a larger volume, in hopes that this work being set on foot, posterity would go on with it." Cotton Mather did go on with it, immediately upon his entrance to the ministry; and by their preaching, publications, correspondence at home and abroad, and the influence of their learning, talents, industry, and zeal in the work, these two men promoted the prevalence of a passion for the marvelous and monstrous, and what was deemed preternatural, infernal, and diabolical, throughout the whole mass of the people, in England as well as America.
