Numerous instances of diplomatic criticism could probably be found in mediaeval histories or chronicles in addition to the following passages to which reference was made in the text.

Next to the pseud-Ingulf and the chronicler of Battle, the author of the Historia Monasterii Sancti Augustini is the most explicit of our mediaeval commentators upon the Old English diplomata. Although the naïveté of this writer's explanations may provoke a smile, we should really be grateful for any explanation at all. It was in connexion with the foundation charters of this church that a hot dispute between the Abbot and the Primate was brought before the Roman Curia in the reign of Henry II. Fortunately for us this local rivalry caused one of the greatest of the Canterbury scholars to take part in the diplomatic discussion concerning the validity of the above “charters.” This was Gervase the historian, who remarked in connexion with the famous instruments which still occupy the place of honour in our Codices, that the oldest erat rasa et subscripta, ac si esset emendata, et absque sigillo, whilst the next in date multo erat recentior, de qua bulla plumbea…, nova valdè, dependebat. He also notes that objection was made to the material of the bulla and to the phraseology which a Romano stilo dissona videbatur. The History of Ramsey, compiled in the 13th century, preserves some extremely curious notices of Anglo-Saxon charters, including an explanation of the absence of seals which apparently comes from the same source as that previously referred to in connexion with the works of the pseud-Ingulf and Thomas of Elmham.
