Formerly there was a Courtenay chantry in the last bay of this aisle, corresponding with Bishop Brantyngham's chantry on the north side. These became ruinous and were removed early in the nineteenth century. The Courtenay tomb in the south transept is entirely a restoration. The effigies represent Sir Hugh Courtenay, 2nd Earl of Devon, and Margaret de Bohun, his wife. The great brass of their son, Sir Peter Courtenay, also formerly in the chantry, is now in the south choir aisle: it has been sadly injured by being trodden under foot for many hundred years, and is now protected by matting. He was standard bearer to Edward III. and Richard II., and one of the first Knights of the Garter.
The centre window of the south nave aisle is filled with stained glass in memory of those of the Devon Regiment who served in the South African War, 1899-1901. The tablets with their names are in St. Edmund's Chapel. Their flags hang on either side of the window.
The large brass tablet, though, like too many of the memorials in the nave, unnecessarily large and far from meritorious in design, is not without interest. It is to the memory of Major-General Howard Elphinstone, V.C., who was drowned off Ushant in 1890.
Above a tablet of brass to Hugh, 2nd Earl of Devon, and his wife, is a window erected by Sir Edwin Watkin to the memory of Thomas Latimer. The small window to the left, erected by Dean Cowie in memory of his wife, should be noticed.
North Transept.—We have already seen that the two great towers of the cathedral were in their nature transeptal from the beginning. But they were quite separated from the body of the church, the arches connecting them being filled in with strongly built masonry, forming a complete wall. But Quivil, wishing to enlarge the interior of the building, took down these walls, and he set about altering the arches and converting them into the same Decorated style to match this work in the rest of the building. He also altered and transformed the Norman chapels that projected on the east side of each transept. In the north transept one window and two narrow doorways still betray their Norman origin. The open galleries in each transept are connected by a passage with the clerestory. This, too, is Quivil's work, and his windows in the two chapels of St. John and St. Paul, easily distinguishable by their wheel-shape, are interesting.
Here is Chantry's fine statue of the Devonshire artist Northcote, and a tablet to the memory of the men and officers of the 20th (Devon) Regiment who fell in the Crimea. Visitors will notice with interest a fairly successful mural painting representing the resurrection, the soldiers in armour being drawn with considerable spirit.
Sylke Chantry is in the north transept. Sylke was a person of considerable importance in his day, and one who deserved and obtained no little honour from his contemporaries. He administered the affairs of the diocese as vicar-general during the absence of Bishop Courtenay, and also during that of Bishop Fox. In 1499 he was made precentor, and held that office till his death. The priests, grateful for the efforts he had made to further their comfort, decided to keep his obit. The abbot and convent of St. Mary of Cleeve, in Somersetshire, willing to show their sense of obligation to him and Canon Moore, gave yearly to the Dean and Chapter the sum of £6 13s. 4d. to be spent in celebrating their anniversary. Sylke's tomb represents a very ghostly figure with the epitaph, "Sum quod eris, fueram quod es, pro me, precor, ora." The chantry is in the style of the later Gothic, and is one of those "final touches" to the cathedral Archdeacon Freeman esteems so happily imparted to it. The ancient works of the thirteenth-century clock, upon the north wall, have been placed in this chantry, the machinery being in motion though it does not now work any part of the actual clock. The various parts are of different dates; the oldest wheel has been working more or less regularly for about 700 years. The dial represents the sun and moon revolving round the earth in the centre, the varying phases of the moon being indicated.
St. Paul's Chapel is on the east side of the north transept. Attributed to the time of Marshall or his immediate predecessors. On the tiles are the arms of Henry III.'s brother, Richard of Cornwall, who was elected King of the Romans. It is used as a vestry for the lay choral vicars.
South Transept.—Opening from the east wall is the Chapel of St. John the Baptist. It corresponds with that of St. Paul in the north transept. Some of the glass in the windows was placed there at the restoration of 1870. The screen dividing it from the transept is Oldham's work. The chapel is now furnished for private meditation and prayer.
