As we have seen, Count Robert by his charter gives to the Norman house, St. Michael’s Mount with half a hide of land and a market on Thursdays and lands in Amaneth. Comparing this statement with that of Domesday Book, it will be observed that in the latter there is no mention of lands in Amaneth and no mention of the market, although in Domesday markets are frequently mentioned, while on the other hand there is mention made of two hides of land, one of which, Treuthal, the Count has taken from St. Michael to be held of him by Bloyou, the other being held by St. Michael in demesne. The question which arises is: Did the Count restore one half of the usurped lands or, assuming the charter to have been made before Domesday Book (1086) was compiled, did he by a later instrument add half a hide, thereby endowing St. Michael with a moiety of the hide held in demesne? We know from the subsequent history of the lands under discussion that the Bloyous remained in possession of Truthall, which never had a market, and we know that a market was held at Marazion or thereabouts within the Domesday manor of Treiwal. We therefore conclude that the Count’s gift to the Norman abbey was a further act of spoliation, which by connivance of the Conqueror he was allowed to practise against the Cornish monks, and also that his charter was executed subsequent to 1086. The presence of Queen Matilda’s name among the witnesses is the only invalidating element in what we have every reason to regard as an authentic document. Its confirmation by Bishop Leofric, and also the bishop’s postscript, are probably both of them forgeries. To give them the appearance of genuineness the Queen’s name may have been added to the authentic document. Be that as it may, the alleged date, 1085, supposed to have been supplied by the bishop, is impossible, inasmuch as the fourteenth year of indiction with which it is made to synchronise would be either 1070 or 1094. In 1094 the Conqueror was dead, and in 1070 “Henricus puer” was in the second year of his age. It must also be added that the date does not occur in the charter, but is supplied from the cartulary.
