John B. Firth, Constantine the Great: The reorganization of the Empire and the triumph of the Church (1904)
“ It is now universally admitted that the whole legend is a fraud and the letter of Constantine to Sylvester announcing the Donation a forgery of the eighth century. Constantine never persecuted the Church; he never had leprosy; he never contemplated bathing in infants’ blood; he did not receive the rite of baptism until he was on his death-bed, and he did not hand over to the Pope the fee simple and title deeds of Rome and Italy. The Donation of Constantine belongs to the museum of historical forgeries. ”
