“And because in the provinces of our diocese those Indians who are Nagualists adore their _naguals_, and look upon them as gods, and by their aid believe that they can foretell the future, discover hidden treasures, and fulfill their dishonest desires: we, therefore, prescribe and command that in every town an ecclesiastical prison shall be constructed at the expense of the church, and that it be provided with fetters and stocks (con grillos y cepos), and we confer authority on every priest and curate of a parish to imprison in these gaols whoever is guilty of disrespect toward our Holy Faith, and we enjoin them to treat with especial severity those who teach the doctrines of Nagualism (y con rigor mayor á los dogmatizantes Nagualistas).”[18-*] In spite of these injunctions it is evident that he failed to destroy the seeds of what he esteemed this dangerous heresy in the parishes of his diocese; for his ninth Pastoral Letter, in which he exposes at length the character of Nagualism, is dated from the metropolitan city of Ciudad Real, on May 24, 1698. As much of it is germane to my theme, I translate as follows: “There are certain bad Christians of both sexes who do not hesitate to follow the school of the Devil, and to occupy themselves with evil arts, divinations, sorceries, conjuring, enchantments, fortune-telling, and other means to forecast the future. “These are those who in all the provinces of New Spain are known by the name of _Nagualists_. They pretend that the birth of men is regulated by the course and movements of stars and planets, and by observing the time of day and the months in which a child is born, they prognosticate its condition and the events, prosperous or otherwise, of its life; and the worst is that these perverse men have written down their signs and rules, and thus deceive the erring and ignorant.
