gable comes another English feature, a very large three-light window running up to the very vault; at the top the mullions of each light are carried up so as to intersect, with cusped circles filling in each space, while the whole window to the top is filled with a veil of small reticulated tracery. Above the top of the large window there is a band of reticulated panelling whose shafts run down till they reach the crocketed hood-mould of the window: and above this an elaborately pierced and foliated parapet between the square pinnacles of the angle buttresses, which like these of the apses are remarkable for the extraordinary number (ten) of offsets and string courses. The next five bays of the nave as well as the whole north side (which has no buttresses) above the cloister are all practically alike; the buttresses, pinnacles and parapet are just the same as those of the transept: the windows tall, standing pretty high above the ground, are all of three lights with tracery evidently founded on that of the large transept window, but set very far back in the wall with as many as three shafts on each side, and with each light now filled in with horrid wood or plaster work. The clerestory windows, also of three lights with somewhat similar tracery, are separated by narrow buttresses bearing square pinnacles, between which runs on a pointed corbel table the usual pierced parapet, and by strong flying buttresses, which at least in the western bays are doubly cusped, and are, between the arch and the straight part, pierced with a large foliated circle and other tracery. The last three bays on the south side are taken up by the Founder's Chapel (Capella do Fundador), in which are buried King João, Queen Philippa, and four of their sons. This chapel, which must have been begun a good deal later than the church, as the church was finished in 1415 when the queen died and was temporarily buried before the high altar, while the chapel was not yet ready when Dom João made his will in 1426, though it was so in 1434 when he and the queen were there buried, is an exact square of about 80 feet externally, within which an octagon of about 38 feet in diameter rises above the flat roof of the square, rather higher than to the top of the aisles. Each exposed side of the square is divided into three bays, one wider in the centre with one narrower on each side. The buttresses, pinnacles and corbel table are much the same as before, but the parapet is much more elaborate and more like French flamboyant. Of the windows the smaller are of four lights with very elaborate and unusual flowing tracery in their heads; small parts of which, such as the tracery at the top of the smaller lights, is curiously English, while the whole is neither English nor French nor belonging to any other national school. The same may be said of the larger eight-light window in the central bay, but that there the tracery is even more elaborate and extravagant. The octagon above has buttresses
