Bishop Seffrid II. (1180-1204) rebuilt the clerestory, and made it loftier than the triforium. The style is Early English. It will be noticed that the middle arch of the windows is round and higher than the side arches, which are pointed. The windows are separated by small shafts of Petworth marble, and the capitals are carved with leaves of palm trees. The Cathedral is dedicated to the Holy Trinity, and the builders seem to have wished to express symbolically the threefold nature of the Deity by the triplicity of the work. Triple clustered shafts appear everywhere. The vaulting is of stone, and is a little later than Seffrid's work. Alarmed by the fires, the architect determined to build a stone and chalk roof instead of wood. In the sixteenth century this vaulting was painted in gaudy colours by Bishop Sherbourne. Two storeys of the south-west tower are original Norman work, with rude cushion capitals, and formed part of the first church finished by Bishop Ralph. This is used as a baptistry, and has a modern font, an imitation of that at Shoreham. In the _South Aisle_ are the Chapels of St. George and St. Clement. The latter has been restored in memory of the last good bishop, Durnford. The figures placed in the old wall arcade are SS. Anselm, Clement and Alphege. The old piscina and aumbrey remain, as also in the other chapel. The chapels were added in the second half of the thirteenth century. The _North Aisle_ resembles the south. Here were the Chapels of St. Anne, St. Theobald or the Four Virgins, and SS. Thomas and Edmund. The screen, pulpit and lectern are all modern, and also the glass. The _monuments_ here are:--in the south aisle, Bishop Durnford (1895), and Captain Cromwell (Flaxman); and in the north aisle, Poet Collins, Richard Fitz-Alan, Earl of Arundel and his wife [the earl was a supporter of the Duke of Gloucester, uncle of Richard II., and was beheaded in 1397], an unknown lady, supposed to be Countess of Arundel (1270). This tomb is of Decorated design, and is beautifully executed. [Illustration The Presbytery.]
