The large piers are composed of clustered shafts with richly carved capitals of foliage. From these spring mouldings. The top of each arch touches the string-course, and then comes the triforium, so beautiful here with its row of double arches, each one sub-divided into two lights, above which is geometrical tracery. Dog-tooth ornament decorates the mouldings of these triforium arches, and also the string-course that separates the triforium from the clerestory. The clerestory windows are curious: spherical triangles enclosing three circles with quatrefoil cusps. Dog-tooth ornamentation runs around the windows. A large circle with five cusps ornaments the spandrels of most of the pier-arches across which the vault shaft passes. At the intersection of the various ribs (five ribs) are finely carved bosses. Much of the effect is obtained from the size of the triforium. The glass in the big west window dates from 1869, a memorial to Canon Hutchinson, who was a zealous worker for the Cathedral’s restoration, by Sir Gilbert Scott. In the north aisle of the nave we note the tablet placed there by Ann Seward to the memory of her father, Canon Seward, his wife and daughter, upon which Sir Walter Scott added lines to the memory of the poetess. There is also a neighbouring tablet to Lady Mary Wortley Montagu, who was born in Lichfield. In the =north transept= we find a curious monument to Dean Heywood (died 1492) showing the skeleton of this worthy. The upper part (which represented him in full canonical costume) has gone. Similar monuments are in Exeter and Lincoln. In the =South Transept= there are busts and memorials to Dr. Samuel Johnson, a native of Lichfield (died 1784), and to David Garrick (died 1779), an early resident of Lichfield. In the first bay of the aisle, there is a monument to the officers and men of the 80th Regiment (Staffordshire Volunteers), over which hang colours taken from the Sikhs. At the south end we note a fine altar to one of Nelson’s captains, Admiral Sir William Parker (died 1866). Note the big south window (Perpendicular) in which there is some Herkenrode glass (see page 212). There is another memorial window in the south aisle of the nave to the officers of the 64th (2d Staffordshire Regiment) who fell in the Indian Mutiny. The =Transepts=, as we have seen, were built before the nave. Each consists of three bays with eastern aisles. Most of the windows are Perpendicular.
