She even went much farther than this in persecuting the good man while he was writing his sermon: she threw large books at his head. But he struggled manfully against these buffetings of Satan, as he considered her conduct to be, finished the sermon, related all these circumstances in it, preached, and published it. Richard Baxter wrote the preface to an edition printed in London, in which he declares that he who will not be convinced by all the evidence Dr. Mather presents that the child was bewitched "must be a very obdurate Sadducee." It is so obvious, that, in this whole affair, Cotton Mather was grossly deceived and audaciously imposed upon by the most consummate and precocious cunning, that it needs no comment. I have given this particular account of it, because there is reason to believe that it originated the delusion in Salem. It occurred only four years[i.460] before. Dr. Mather's account of the transaction filled the whole country; and it is probable that the children in Mr. Parris's family undertook to re-enact it. There is nothing in the annals of the histrionic art more illustrative of the infinite versatility of the human faculties, both physical and mental, and of the amazing extent to which cunning, ingenuity, contrivance, quickness of invention, and presence of mind can be cultivated, even in very young persons, than such cases as this just related. It seems, at first, incredible that a mere child could carry on such a complex piece of fraud and imposture as that enacted by the little girl whose achievements have been immortalized by the famous author of the "Magnalia." Many other instances, however, are found recorded in the history of the delusion we are discussing. That of the grandchild of William and Elizabeth Morse, in Newbury, was nearly as marvellous, and perfectly successful in deceiving the whole country except Caleb Powell; and he got into much trouble in consequence of seeing through it. A similar instance of juvenile imposture is related as having occurred at Amsterdam in 1560. Twenty or thirty boys pretended to be suddenly seized with a kind of rage and fury, were cast upon the ground, and tormented with great agony. These fits were intermittent; and, when they had passed off, their subjects did not seem to be conscious of what had taken place. While they lasted, the boys threw up, apparently from their stomachs, large quantities of needles, pins, thimbles, pieces of[i.461] cloth, fragments of pots and kettles, bits of glass, locks of hair, and a variety of other articles. There was no doubt, at the time, that they were suffering under the influence of the Devil; and multitudes crowded round them, and gazed upon them with wonder and horror.
