Apart from such incidents as the Records of the Priory of May indicate, there seems to have been only one event of importance in connection with it for more than a century from the time when King David conveyed it to the Monks of Reading, on condition that they should maintain in it nine priests of their brethren, to offer up the Mass for the benefit of his soul and of the souls of his predecessors and successors, Kings of Scotland. It is briefly referred to by the chronicler Torfæus in his account of one of Swein Asleif's expeditions. Steering southwards, he says, Swein and his followers arrived at the Isle of May. In that island there was a monastery, the abbot of which was named Baldwin. Being detained there for seven days, they professed to be ambassadors from Earl Ronald to the King of Scotland. The monks, suspecting them to be robbers, sent to the mainland for help. On this, Swein plundered the monastery, and took much booty. As a strangely inconsistent sequel to this story, Torfæus adds that Swein then sailed up the Firth of Forth, and found King David in Edinburgh; that the King received Swein with much honour, and entreated him to remain; and that Swein told David all that had occurred between him and Earl Ronald, and how he had plundered the Isle of May. The same historian also states that on another occasion Swein anchored at the Isle of May, from which he dispatched messengers to the King at Edinburgh.[220] Spottswood states, in his _List of Religious Houses in Scotland_, that the Priory of the May, originally put under the patronage of All Saints, was subsequently consecrated to the memory of St. Adrian. He does not, however, mention on what occasion. He adds that William Lamberton, Bishop of St. Andrews, purchased it from the Abbot of Reading, and notwithstanding the complaints made thereupon by Edward Longshanks, King of England, bestowed it upon the canons regular of his cathedral. Fordun and Prynne both give details of the transaction; but from documents discovered at a later date and published in the _Records of the Priory of the Isle of May_,[221] it appears that neither of them states the case quite fully nor quite correctly. It is to be gathered from the proceedings relative to the claim of the Abbot and Convent of Reading on the Priory, that it was Robert de Burghgate, Abbot of Reading, who sold the Scottish "cell" to William, Bishop of St. Andrews, and that he received from him 1100 merks on account of the price. It would seem, however, that he effected this transaction contrary to the wish of the majority of his monks; and, on this ground, his successor, Abbot William, attempted to overturn it. In the Parliament of John Baliol, held at Scone on the 10th of February, 1292, John Sutton and Hugh Stanford, appearing as his representatives, demanded either possession of the Priory of May or payment of the balance of the price agreed to be paid for it, together with the fruits and rents accruing from it during
