The building consists of an arcade of nine semicircular arches supported on eight Doric columns. The upper storey, containing the library, has eleven windows in a similar classical style, and above there is a bold entablature ornamented with acanthus leaves. The library is 104 ft. long by 17 ft. 6 in. wide and 14 ft. high; the ceiling is flat and perfectly plain. In addition to the windows above mentioned there is another at the west end. The entrance is at the east end through a richly ornamented door (fig. 125). The shield in the centre of the pediment bears the arms of Dean Honywood. Wren placed a continuous bookcase along the north wall of this room, extending from floor to ceiling. At the base there is a plinth (fig. 125), which may have originally contained cupboards, but is now fitted with shelves; and at the top, close to the ceiling, there is a heavy entablature decorated with acanthus leaves and classical moldings above a plain cornice, which bears at intervals oblong tablets inscribed with the subjects of the books beneath. The shelves are disposed in compartments, alternately wide and narrow, the former being set slightly in advance of the latter, so as to break the monotony of a bookcase of uniform width extending the whole length of a long room. While this work was proceeding Wren planned the New Library for Trinity College, Cambridge[507], begun 23 February, 1675-6. His design is accompanied by an explanation, contained in a rough draught of a letter to some gentleman of Trinity College, probably the Master. It is not signed, but internal evidence shews that it must have been written or dictated by Wren. This library was placed on a cloister, open both to the east and to the west, at the end of Nevile's Court. The level of the library floor was made to correspond with that of the first floor of the chambers on the north and south sides of the court. This is shewn in Wren's design, part of which is here reproduced (fig. 126), and explained in the following passage of his memoir. [Illustration: Fig. 126.
