There is yet another document of great importance. It is described in the Otterton custumal[125] as the Erection (_Constructio_) of the Priory of St. Michael in Cornwall. It is, in reality, a notification by Bernard, abbot of the Norman house, that the church of Blessed Michael of Cornwall, built by him in 1135, was consecrated in his presence by Robert (Chichester), bishop of Exeter, that, with the advice of the said Pontiff and of Count Raner, and with the approbation of the barons of the province, he has got together thirteen brethren and has made provision for them out of old endowments and current contributions, that he has enacted that he who shall be selected by the parent house to be prior of St. Michael’s Mount shall not fail to make a return to it of 16 marks yearly, that if he shall prove refractory he shall be degraded and another prior appointed by the abbot with the abbey’s consent, and so on. Moreover, the Cornish brethren are to receive the benediction of the monastic order from the abbot _in Monte Tumba_ unless perchance it please him to come to Cornwall and bless them there. At the end of the instrument there is a list of the possessions of the Blessed Michael of Cornwall, given to the archangel by Count Robert of Mortain, viz. Tremaine, where there is sufficient land for two ploughs, Trahorabohc for three, Listyahavehet for three, Treganeis for two, Carmahelech for two. The entire document is needlessly defiant and menacing. The Cornish house is reduced to a mere appanage of the abbey and the prior to a mere collector of 16 marks for its benefit. Every vestige of independence is swept away, and that, too, in subversion of the primary principle of the saintly founder of the order. One hardly expected to find evidence in Cornwall in confirmation of Dante’s description given more than a century later. The walls, for abbey reared, turned into dens (of thieves), The cowls to sacks, choked up with musty meal. It is therefore satisfactory to note that the priory could only reckon among its possessions the lands given by the Count of Mortain, the rest of St. Michael’s lands having either been confiscated or alienated between the date of the Domesday Survey (1086) and that of the document (1135).
