this form of arch all through the Gothic period."[233] Each compartment of the apse has a central boss, and there is a considerable amount of carved woodwork in the crypt--some of the fifteenth or sixteenth century, and some later. The choir that was recently taken down superseded an older one, and it is probably to this former choir that references are contained in the _Council Register_ for about a century from 1442. _Old Aberdeen, King's College._--Of Bishop Elphinstone of Aberdeen (1488-1514) it is said: "With no private fortune, and without dilapidating his benefice, he provided for the buildings requisite for his University and Collegiate Church, and for the suitable maintenance of its forty-two members; and the Cathedral Choir, the King's College, and the old gray bridge spanning the valley of the Dee are monuments to his memory that command the respect of those who have no sympathy with his Breviary, rich in legends of Scottish Saints, and who would scarcely approve of his reformed Gregorian chant."[234] The college was dedicated to the Holy Trinity and the Virgin Mary, and being placed under the immediate protection of the King, came to be known as King's College.
