Valla (1407-1457) was the most important theorist of the humanist movement. His most famous work is the present volume, an oration in which Valla uses new philological methods to attack the authenticity of the most important document justifying the papacy's claims to temporal rule.

The Donation of Constantine is the most outrageous and powerful forgery in world history. The question of its precise time of origin alone kept generations of researchers occupied. But, what exactly is the Donation of Constantine? To find the answer, it is necessary to approach the question on two different semantic levels: First, as the Constitutum Constantini, a fictitious privilege, in which, among other things, rights and presents were bestowed on the catholic church by a grateful Emperor Konstantin. Secondly, as a reflection of the Middle Age mindset, becoming part of the culture landscape midway through 11th century A.D. The author not only reinterprets the origin of this forgery (i.e. puts it down to the Franks’ opposition of Emperor Louis the Pious), but retells, as well, the history of its misinterpretation since the High Middle Ages. In an appendix, all relevant texts are printed in the original language, an English translation is provided.

The Donation of Constantine (Latin: Donatio Constantini) is a forged Roman imperial decree by which the 4th-century emperor Constantine the Great supposedly transferred authority over Rome and the western part of the Roman Empire to the Pope.

How was the history of post-classical Rome and of the Church written in the Catholic Reformation? Historical texts composed in Rome at this time have been considered secondary to the city's significance for the history of art. The Invention of Papal History corrects this distorting emphasis and shows how historical writing became part of a comprehensive formation of the image and self-perception of the papacy. By presenting and fully contextualising the path-breaking works of the Augustinian historian Onofrio Panvinio (1530-1568), Stefan Bauer shows what type of historical research was possible in the late Renaissance and the Catholic Reformation. Crucial questions were, for example: How were the pontiffs elected? How many popes had been puppets of emperors? Could any of the past machinations, schisms, and disorder in the history of the Church be admitted to the reading public? Historiography in this period by no means consisted entirely of commissioned works written for patrons; rather, a creative interplay existed between, on the one hand, the endeavours of authors to explore the past and, on the other hand, the constraints of ideology and censorship placed on them. The Invention of Papal History sheds new light on the changing priorities, mentalities, and cultural standards that flourished in the transition from the Renaissance to the Catholic Reformation.
