During the twelfth century the ecclesiastical monopoly of book-making began to give way. Literary work had grown irksome. The church had secured a position of supremacy in temporal as well as spiritual matters; it had grown rich, and showed disregard for the spiritual and educational means by which its successes had been made. It began to enjoy its prosperity. The neglect of books by many of the priests of the thirteenth century was authorized by the example and precepts of Francis d’Assisi, who suffered none of his followers to have Bible, breviary or psalter. This new form of asceticism culminated in the establishment of the order of the Mendicant Friars, which, in its earlier days, was wonderfully popular. Founded for the purpose of supplying the spiritual administrations which had been sadly neglected by the beneficed clergy, who were not only ignorant but corrupt,[71] the new order ultimately [p159] became even more neglectful of duty, more ignorant and more immoral. The leaders of the friars were men of piety, and some of them, disregarding the precept of the zealous founder of the order, were students and collectors of books; but the inferior clergy, with few exceptions, were extremely ignorant. They not only exerted a mischievous influence upon the people, but they showed to priests of other orders that the knowledge to be had from books was not really necessary. The class of monks who had devoted their lives to the copying, binding and ornamenting of books, imitated as far as they could the example set by the pleasure-loving, ignorant friars, and sought opportunities for relaxation.[72] The care of libraries was neglected for pleasures of a grosser nature. The duties of copyists and librarians passed, gradually and almost imperceptibly, into the hands of the laity. The business of selling books, which had been given up during the decline of the Roman empire, re-appeared in the latter part of the twelfth century in the neighborhood of the new Italian universities of Padua and Bologna. To have the privilege of selling books to the students, the booksellers were [p160] obliged to submit to a stringent discipline. The restrictive legislation of the University of Paris, for four centuries the greatest school of theology and the most renowned of the European universities, may be offered as a suitable illustration of the spirit shown to booksellers by all the schools of the middle ages. Through its clerical teachers, the church claimed the right to control the making, buying and selling of books. It extended its authority over parchment-makers, bookbinders, and every other class of mechanics that contributed in any way to their manufacture. The rules made by this university reveal many curious facts concerning book-making, and teach us, as a recent imperialist author has truly said, that the censorship of books is older than printing.
