Though the nave is like that of Santiago, the transepts and choir are much simpler. There the transept is long and has an aisle on each side; here it is short and aisleless. There the choir is deep with a surrounding aisle and radiating chapels, here it is a simple apse flanked by two smaller apses. Indeed throughout the whole of the Peninsula the French east end was seldom used except in churches of a distinctly foreign origin, such as Santiago, Leon or Toledo in Spain, or Alcobaça in Portugal, and so it is natural here to find Bernardo rejecting the elaboration and difficult construction of his model, and returning to the simpler plan which had already been so often used in the north. (Fig. 18.) Inside the piers are square with four half-shafts, one of which runs up in front to carry the barrel vault, which is about sixty feet high. All the capitals are well carved, and a moulded string which runs along under the gallery is curiously returned against the vaulting shafts as if it had once been carried round them and had afterwards been cut off. Almost the only light in the nave comes from small openings in the galleries, the aisle windows being nearly all blocked up by later altars, and from a large window at the west end. The transept on the other hand is very light, with several windows at either end, and eight in the square lantern, so that the effect is extremely good of the dark nave followed by the brilliant transept and ending in a great carved and gilt reredos. This reredos, reaching up to the blue-and-gold apse vault, was given to the cathedral in 1508 by Bishop D. Jorge d'Almeida, and was the work of 'Master Vlimer a Framengo,' that is, a Fleming, and of his partner, João D'ipri, or of Ypres, two of the many foreigners who at that time worked for King D. Manoel. There are several picturesque tombs in the church, especially two in the north-east corner of the transept, whose recesses still retain their original tile decoration. Later tiles still cover the aisle walls and altar recesses, but beautiful examples of the Mozárabe or Moorish style which once covered the piers of the nave, as well as the wooden choir gallery with its finely panelled under side, have been swept away by a recent well-meaning if mistaken restoration. The outside of the church is more unusual than the inside. The two remaining original apses are much hidden by the sacristy, built probably by Bishop Jorge de Castello Branco in 1593, but in their details they are greatly like those of the church of San Isidoro at Leon, and being like it built of fine limestone, are much more delicately ornamented than are those of any of the granite churches further north. The side aisles are but little lower than the central aisle or than the transepts, and are all crowned with battlements very like those on the castle of Guimarães. The buttresses are only shallow strips, which in the transepts are united by round arches, but in the
