GILBERT de Moravia, fourth bishop, had been Archdeacon of Moray previous to his elevation to the see of Caithness in 1223. He built the cathedral at Dornoch, and his charter of constitution[150] is still extant in the record-room at Dunrobin Castle. For many years there had been an intimate connection between the diocese of Caithness and the abbey of Scone,[151] and in the constitution of his cathedral Bishop Gilbert named the Abbot of Scone one of the canons. The fourteen churches assigned to the prebends were those of Clyne, Dornoch, Creich, Rogart, Lairg, Farr, Kildonan, and Durness, in Sutherland; and Bower, Watten, Skinnet, Olrig, Dunnet, and Canisbay, in Caithness. Golspie and Loth, Reay, Thurso, Wick, and Latheron, were reserved to the bishop. He seems to have been a man of mark in his time. He built the “Bishop’s Castle” at Scrabster, and was made keeper of the king’s castles in the north.[152] He seems also to have been the first discoverer of gold in Sutherlandshire, for Sir Robert Gordon states that he “found a mine of gold in Duriness, in the lands belonging to his bishoprick.” He died at Scrabster in 1245, and was afterwards canonised. His relics were preserved in the cathedral church at Dornoch, and continued to be held in reverence down to the middle of the 16th century. In a record of the year 1545 it is stated that the parties compearing before Earl John of Sutherland in the chapter-house of the cathedral at Dornoch made oath by touching the relics of the blessed Saint Gilbert. He is the only bishop of Caithness, except Bishop Adam, whose death is recorded in the Icelandic Annals. The entry is under the year 1244:—“Death of Gilibert, bishop in Scotland.” WILLIAM, fifth bishop, was his successor. In 1250 he appears among the other Scottish bishops in a document addressed to Alexander III. concerning the liberties of the Church. He died in 1261 or 1262. WALTER de Baltrodin, a canon of Caithness, was chosen as his successor. Pope Urban IV. in 1263 addressed a letter[153] to the bishops of Dunkeld, Brechin, and Ross, setting forth that his election had not been proceeded with according to canonical form, but as it had been unanimous, and in consideration of the poverty of the Church, and the expense of making such long journeys to distant places, he enjoins them to prefer the said Walter to the bishopric if they find that he is not disqualified by defect of birth or otherwise. He died before 1274. On his death, Nicolas, Abbot of Scone, was chosen as his successor, but rejected by the Pope.[154]
