[2] Either Bower is confused or Matthew changed his name or took a pseudonym more appropriate to the environment of the "international" church, a practice not unusual in the period.
[3] He was given the title of Magister ("Master") by Bower, indicating the completion of a university education and more particularly of a Masters' degree at some stage in his life, but details of this have not survived and the title may be spurious.
[6] He travelled to the papal court at Orvieto, along with the archdeacon Robert de Fyvie, and without waiting very long, was consecrated by Pope Gregory X personally (per nos ipsos) by 28 December 1272, on which date a mandate was issued authorising him to proceed to his bishopric.
[7] Presumably after returning to Ross, he travelled back to continental Europe to attend the Second Council of Lyon in France, held in the summer of 1274.
[8] Whether or not Bower's claim about his death at Lyons is true, the bishopric was certainly vacant by the following Christmas.
