The papal claim to temporal supremacy in the Western world rested largely on a spurious document known as the Donation of Constantine. In this the emperor is represented as withdrawing from Rome in order to leave it to the pope, to whom, in return for being cured of leprosy, he gives the whole Occident. An uncritical age had received this forgery for five or six centuries without question. Doubt had been cast on it by Nicholas of Cusa and Reginald Peacock, but Valla demolished it. He showed that no historian had spoken of it; that there was no time at which it could have occurred; that it is contradicted by other contemporary acts; that the barbarous style contains {49} expressions of Greek, Hebrew, and German origin; that the testimony of numismatics is against it; and that the author knew nothing of the antiquities of Rome, into whose council he introduced satraps. Valla's work was so thoroughly done that the document, embodied as were its conclusions in the Canon Law, has never found a reputable defender since. In time the critique had an immense effect. Ulrich von Hutten published it in 1517, and in the same year an English translation was made. In 1537 Luther turned it into German. [Sidenote: Valla attacks the Pope] And if the legality of the pope's rule was so slight, what was its practical effect? According to Valla, it was a "barbarous, overbearing, tyrannical, priestly domination." "What is it to you," he apostrophizes the pontiff, "if our republic is crushed? You have crushed it. If our temples have been pillaged? You have pillaged them. If our virgins and matrons have been violated? You have done it. If the city is innundated with the blood of citizens? You are guilty of it all." [Sidenote: Annotations on the New Testament] Valla's critical genius next attacked the schoolman's idol Aristotle and the humanist's demigod Cicero. More important were his _Annotations on the New Testament_, first published by Erasmus in 1505. The Vulgate was at that time regarded, as it was at Trent defined to be, the authentic or official form of the Scriptures. Taking in hand three Latin and three Greek manuscripts, Valla had no difficulty in showing that they differed from one another and that in some cases the Latin had no authority whatever in the Greek. He pointed out a number of mistranslations, some of them in passages vitally affecting the faith. In short he left no support standing for any theory of verbal inspiration. He further questioned, and successfully, the authorship of the Creed attributed {50} to the Apostles, the authenticity of the writings of Dionysius the Areopagite and of the letter of Christ to King Abgarus, preserved and credited by Eusebius.
