word “library” was understood to mean the Holy Scriptures; they were ignorant of the existence of any other books. The immense advantages accruing to the clergy from the habitual use of an idiom unfamiliar to the vulgar, as well as from the monopoly of the simplest rudiments of knowledge, were not lost upon these shrewd observers of human nature. The church became the point whence royal edicts were promulgated and where commercial bargains were concluded. Proclamations were issued at its doors. Contracts were entered into before its altar. Oaths were taken upon the Scriptures and the crucifix. The Host was used in the detection of criminals and in the solemnization of treaties. Land was conveyed by the mere transfer of a twig or a clod of earth in the presence of clerical witnesses. The cross still traced upon legal documents by the hands of the illiterate, in lieu of a signature, is a suggestive reminiscence of an age when the potency of ecclesiastical influence was recognized in every important transaction of life. The persecution of learning was systematized and maintained, first, by the creation of theological odium, and subsequently by the institution of such tribunals as the Holy Office; not through a desire to preserve a becoming reverence for religious worship, but from a consciousness of the inability of the existing system to withstand the examination of reason. Heresy was a convenient and ever available pretext for crushing that independence of thought which threatened the integrity of doctrine or the permanence of sacerdotal supremacy. The Inquisition was, when its real object is considered, as has already been stated, a temporal rather than an ecclesiastical device. Its unspeakable atrocities and their effects are too well known to require description. In refutation of its claim as a means of moral purification may be introduced the indisputable fact that during the period of its greatest power the worst atheists, blasphemers, and criminals in Europe were to be found masquerading in the cowl and the surplice. The outrages it committed on humanity must be regarded as the legitimate results of the papal system, which, inheriting to a great extent the organization, the prestige, and the traditions of imperial authority, encouraged, by immunity purchased with corruption and by the profligate example of the Holy See, the neglect of every duty and the commission of every crime. The exercise of the faculties of the human mind in the Dark Ages, when they were permitted to develop and be employed for the benefit of the Church,--their only profitable patron,--are eminently suggestive of the capacity which it possessed when afforded encouragement. The cathedrals, the carvings, and the missals, which, in their respective departments of art, far surpass the efforts of modern times, are appropriate examples of the scope and fertility of mediæval genius.
