Raphael De La Torre and Adam Tanner published treatises establishing the right and duty of ecclesiastical tribunals to punish all who practised or dealt with the arts of demonology. In 1484, Sprenger came out with his famous book, "Malleus Maleficarum;" or, the "Hammer of Witches." Paul Layman, in 1629, issued an elaborate work on "Judicial Processes against Sorcerers and Witches." The following is the title of a bulky volume of some seven hundred pages: "Demonology, or Natural Magic or demoniacal, lawful and unlawful, also open or secret, by the intervention and invocation of a Demon," published in 1612. It consists of four books, treating of the crime of witchcraft, and its punishment in the ordinary tribunals and the Inquisitorial office. Its author was Don Francisco Torreblanca Villalpando, of Cordova, Advocate Royal in the courts of Grenada. It was republished in 1623, by command of Philip III. of Spain, on the recommendation of the Fiscal General, and with the sanction of the Royal Council and the Holy Inquisition. This work may be considered as establishing and defining the doctrines, in reference to witchcraft, prevailing in all Catholic countries. It was indorsed by royal, judicial, academical, and ecclesiastical approval; is replete with extraordinary erudition, arranged in the most scientific form, em[i.362]bracing in a methodical classification all the minutest details of the subject, and codifying it into a complete system of law. There was no particular in all the proceedings and all the doctrines brought out at the trials in Salem, which did not find ample justification and support in this work of Catholic, imperial, and European authority. But perhaps the writer of the greatest influence on this subject in England and America, during the whole of the seventeenth century, was William Perkins, "the learned, pious, and painful preacher of God's Word, at St. Andrew's, in Cambridge," where he died, in 1602, aged forty-four years. He was quite a voluminous author; and many of his works were translated into French, Dutch, Italian, and Spanish. Fuller, in "The Holy State," selects him as the impersonation of the qualities requisite to "the Faithful Minister." In his glowing eulogium upon his learning and talents, he says:—
