Apart from the general injunction in this “Constitution,” it contains a specific prohibition of the treatise on Monarchy by Antonio Roselli, and of the theses of Pico della Mirandola. Those who have printed or who may hereafter print these works, or who may have bought or come into the possession of copies, are ordered, under penalty of excommunication, to deliver such copies at once for destruction. Roselli was professor of law in Siena and later in Padua. His treatise _De Monarchia_ had been printed in Venice in 1483 and in 1487. His name stands in all the Roman Indexes except in that of Trent, and thereafter with the proviso _donec corrigatur_. Pico escaped official classification as a heretic and no one of his writings finds place in the Index. In 1487, he had brought before the public no less than nine hundred theses which he was prepared to defend against all critics. The pope ordered an examination to be made of these theses (propositions) by a commission of theologians and jurists. The commission found that thirteen of the theses were tainted with heresy. Pico, while maintaining the orthodoxy of his propositions, expressed his readiness to submit himself to the judgment of the pope. Six years later, he was able to secure from Alexander VI a further examination, conducted by three cardinals and the _Magister Palatii_, and on the report of this commission, the pope declared Pico to be free from suspicion of heresy. _1501._ _Alexander VI_, in a Bull entitled _Inter Multiplices_, addressed to the Archbishop of Magdeburg and to the rulers of the three ecclesiastical principalities, says: “The art of printing can be of great service in so far as it furthers the circulation of useful and tested books; but it can bring about serious evils if it is permitted to widen the influence of pernicious works. It will, therefore, be necessary to maintain full control over the printers so that they may be prevented from bringing into print writings which are antagonistic to the Catholic faith, or which are likely to cause trouble to believers.” The Bull proceeds to state that in the dioceses of Cologne, Mayence, Treves, and Magdeburg many books and tracts are being sent out from the presses which contain pernicious errors, wrong doctrine, and heresies; and prohibits, under pain of the excommunication _latae sententiae_, any further printing of such books, and also the possession or perusal of the same. The bishops and inquisitors are charged with the execution of the decree; and are ordered to enforce its provisions against all persons, whatever their rank or positions, and also against colleges, universities, and associations, with the threat that, in case of opposition or evasion, the penalties shall be sharpened and multiplied. The civil powers are to be invoked if necessary, and in order to strengthen the interest of the local authorities, they are to receive one half the amounts of the penalties collected in money.
