Here I must first clear the ground by explaining as to the "three patents of creation" mentioned in this passage, that there were only _two_ charters (not "patents") of creation—that of the king, which survives in the original, and that of the Empress, which is known to us from a transcript. As to the latter, it certainly "passed in the short period during which Maud was in London," but that period, so far from being "between June 24 and July 25, 1141," consisted only of a few days ending with "June 24, 1141." The main point, however, at issue is the priority of the creation-charters. It will be seen that Mr. Eyton jumped at his conclusion, and then proceeded: "Having decided," etc. This is the more surprising because that conclusion was at variance with what he admits to have been his own principle, namely, that he had "usually found counter-charters to be Maud's."[117] In this case his conclusion was wrong, and his original principle was right. I think that Mr. Eyton's error was due to his ignorance of the second charter granted by the king to Geoffrey.[118] As he was well acquainted with the royal charters in the duchy of Lancaster collection it is not easy to understand how he came to overlook this very long one, which is, as it were, the keystone to the arch I am about to construct. It is my object to make Geoffrey's charters prove their own sequence. When once arranged in their right order, it will be clear from their contents that this order is the only one possible. We must not attempt to decide their dates till we have determined their order. But when that order has been firmly established, we can approach the question of dates with comparative ease and confidence. To determine from internal evidence the sequence of these charters, we must arrange them in an ascending scale. That is to say, each charter should represent an advance on its immediate predecessor. Tried by this test, our four main charters will assume, beyond dispute, this relative order. (1) First charter of the king. (2) First charter of the Empress. (3) Second charter of the king. (4) Second charter of the Empress. The order of the three last is further established by the fact that the grants in the second are specifically confirmed by the third, while the third is expressly referred to in the fourth. The only one, therefore, about which there could possibly be a question is the first, and the fact that the second charter represents a great advance upon it is in this case the evidence. But there is, further, the fact that the place I have assigned it is the only one in the series that it can possibly occupy. Nor could Mr. Eyton have failed to arrive at this conclusion had he included within his sphere of view the second charter of the king.
