Ecclesiastical censorship, however, was not the outcome of the Universities' assumption of control over the book trade. It sprang from the jealousy of the clergy, who opposed the spread of knowledge among the people--some, perhaps, because they knew that knowledge in ignorant hands is dangerous, and others because they feared their own prestige might suffer. This feeling existed before printing, though printing brought it to a head. For instance, in 1415 the penalty in this country for reading the Scriptures in the vernacular was forfeiture of land, cattle, body, life, and goods by the offenders and their heirs for ever, and that they should be condemned for heretics to God, enemies to the Crown, and most errant traitors to the land. They were refused right of sanctuary, and if they persisted in the offence or relapsed after a pardon were first to be hanged for treason against the King and then burned for heresy against God. Thus the clergy upheld and encouraged a censorship of the press. As early as 1479 Conrad de Homborch, a Cologne printer, had issued a Bible accompanied by canons, etc., which was "allowed and approved by the University of Cologne," and in 1486 the Archbishop of Mentz issued a mandate forbidding the translation into the vulgar tongue of Greek, Latin, and other books, without the previous approbation of the University. Finally, in 1515, a bull of Leo X. required Bishops and Inquisitors to examine all books before they came to be printed, and to suppress any heretical matter. The Vicar of Croydon, preaching at St Paul's Cross about the time of the spread of the art of printing, is said to have declared that "we must root out printing or printing will root out us." But an ecclesiastical censorship over the English press was not established until 1559, when an Injunction issued by Queen Elizabeth provides that, because of the publication of unfruitful, vain, and infamous books and papers, "no manner of person shall print any manner of boke or paper ... except the same be first licenced by her maiestie ... or by .vi. of her privy counsel, or be perused and licensed by the archbysshops of Cantorbury and Yorke, the bishop of London," etc. The Injunction extended also to "pampheletes, playes, and balletes," so that "nothinge therein should be either heretical, sedicious, or vnsemely for Christian eares." Classical authors, however, and works hitherto commonly received in universities and schools were not touched by the Injunction. CHAPTER V LIBRARIES IN MEDIÆVAL TIMES
