Very important work of early history. Lorenzo Valla uses logic, philosophical argument, a thorough knowledge of Roman history, and a classical education steeped in Latin literature to prove that the Donation of Constantine, a centuries-old document in which Emperor Constantine cedes his power to Pope Sylvester, was a forgery. The text of the Coleman translation (or really any translation of Valla) is difficult not because of the prose, but because of the assumed knowledge of Roman history and the classics on the part of the reader. There is much that cannot be appreciated without doing a deep-dive into the Latin literature of the Dark and Middle Ages. Still, Valla unleashes some hilarious criticisms and shows his frustration about the longstanding hoax, as well as his annoyance that multiple popes would cite the Donation of Constantine as support for their Earthly power.
