During Bishop Cameron’s reign the episcopal see was at the highest point of its power and splendour. The prebendaries, who were originally seven in number, were now increased to thirty-two, and the bishop required that they should all have manses,[62] and reside near the cathedral. The Episcopal Court thus became of great extent and importance, and was said to rival that of the king. Bishop Cameron died in 1446. He was succeeded by Bishop William Turnbull, the founder of Glasgow University. His arms appear on the upper part of the chapter house wing. Bishop Robert Blackadder was consecrated in 1484. We have already met with this prelate in connection with Jedburgh Abbey and Edrom Church. In his time the see was erected into an archbishopric. A building in continuation of the south transept, called Blackadder’s Aisle, was partly erected by him, but was never carried higher than the ground story or crypt. This archbishop was the last occupant of the see who added much to the adornments of the cathedral. He founded altarages, and erected two altars, on which his arms and initials are carved, in front of the rood screen. Towards the middle of the sixteenth century, it became apparent that the end of the episcopal reign was approaching. Archbishop James Beaton first withdrew all the treasures and valuables from the cathedral into the bishop’s castle; but, finding himself and them insecure there, he retired to France, taking with him what valuables he could, and also the records of the see from the earliest period. The latter were deposited in the Scots College in Paris, and at the time of the French Revolution they were partially saved by the Abbé Macpherson, and sent back to Scotland. These records have now been published by the Maitland Club under the title of _Registrum Episcopatus Glasguensis_, with a valuable introduction by the editor, Professor Cosmo Innes. The cathedral is situated on steep ground sloping eastwards towards the Molindinar Burn, which here runs through a narrow valley on its way southward to the Clyde, which is only a short distance off. Opposite the cathedral, on the eastern bank of the burn, there rises a steep conical hill, now a many-monumented cemetery, from which fine bird’s-eye views of the building may be obtained. The surroundings of the edifice have changed many times since it was built. Till after the Reformation there stood at the west end of the cathedral the Bishop’s Palace, a great fortress covering some acres of ground; but of its many buildings, walls, and towers not a shadow is left. The manses of the prebends have likewise disappeared, and even the Molindinar Burn is buried as a sewer deep below the present surface of the valley. The cathedral is surrounded by the old churchyard, a large open space free from houses, and the structure can thus be well seen on all sides. [Illustration: FIG. 567.--St. Mungo’s Cathedral.
