The charming inner quadrangle, in which the library is, rejoices in the name "Mob" Quad--a name of which the derivation has been lost. Like the Treasury, it probably dates from about 1300. The high-pitched roof of the latter, made of solid blocks of ashlar, is one of the most remarkable features of Merton. The outer sacristy is on the right of the main entrance passage to Mob Quad, and thence an old stone staircase leads to the Treasury or Muniment room. Another passage from the front quadrangle leads to Patey's Quad. The Fellows' Quadrangle was begun in 1608, and the large gateway with columns of the four orders (Roman-Doric, Ionic, Corinthian, and Composite) is typical of the architectural taste of the times. The quadrangle itself, very similar to that of Wadham, is one of the most beautiful and charming examples of late Gothic imaginable. It would have been a fortunate thing if this had been the last building added to Merton. But it was destined that the taste of the Victorian era should be painfully illustrated by the new buildings which were erected in 1864 by Mr Butterfield. The architect was eager and the college not disinclined at that time to destroy part of the library and the Mob Quad. The abominable building which replaced the beautiful enclosure known as the Grove, combines with the new buildings of Christ Church to spoil what might have been one of the most beautiful effects of water, wood and architecture in the world--the view of Oxford from the Christ Church and Broad Walks. Inspired by the example of Merton and a similar dislike of monks and friars, Walter de Stapeldon, the great Bishop of Exeter, ordained that the twelve scholars whom he originally endowed (1314) should not study theology or be in orders. The society, afterwards known as Exeter College, was housed at first in Hart Hall and Arthur Hall, in the parish of S. Peter in the East, and was intended by the founder to be called Stapeldon Hall. In the following year he moved his scholars, eight of whom, he stipulated, must be drawn from Devonshire and four from Cornwall, to tenements which he had bought between the Turl and Smith Gate, just within the walls. The founder added a rector to their number and gave them statutes, based on those of Merton, which clearly indicated that his object was to give a good education to young laymen. The college was practically refounded in 1566 by Sir William Petre, a successful servant of the Tudors. Of the pre-reformation buildings, nothing unhappily remains save a fragment of the tower. The rest is seventeenth century or nineteenth, the front on Turl Street dating from 1834, and the unlovely "modern Gothic" front on Broad Street from 1854. Sir Gilbert Scott, who designed the latter, destroyed the old chapel and replaced it with a copy of the Sainte Chapelle.
