This was the first instance of modern, scientific diplomatics. Independently of both Cusa and Valla, Reginald Pecocke, Bishop of Chichester (1450–57), reached a similar conclusion. Among the indications that the Donation must be a fake are its language and the fact that, while certain imperial-era formulas are used in the text, some of the Latin in the document could not have been written in the 4th century; anachronistic terms such as "fief" were used. Also, the purported date of the document is inconsistent with the content of the document itself, as it refers both to the fourth consulate of Constantine (315) as well as the consulate of Gallicanus (317).
