In each opening these bands are different. In some is Gothic foliage, in others semi-classic carving like the string below or realistic like the cresting. In others are naturalistic branches, and in the opening over the chapel where Dom Manoel was to lie are cut the letters M in one hand and R in the other; Manoel Rey. (Fig. 59.) Only the first foot or so of the vaulting has been built, and there is nothing now to show how the great octagon was to be roofed. Murphy[124] gives his idea; the eight piers carried high up and capped with spires, huge Gothic windows between, and the whole covered by a vast pointed roof--presumably of wood--above the vault. Haupt with his Indian prepossessions suggests a dome surrounded by eight great domed pinnacles. Probably neither is right; certainly Murphy's great roof of wood would never have been made, and as for Haupt's dome nothing domed was built in Portugal till long after and that at first only on a small scale.[125] Besides, the well-developed Gothic ribs which are seen springing in each corner clearly show that some kind of Gothic vault was meant, and not a dome; and that the Portuguese could build wonderful vaults had been already shown by the chapter-house here and was soon to be shown by the transept at Belem. So in all probability the roof would have been a great Gothic vault of which the centre would rise very considerably above the sides; for there is no sign of stilting the ribs over the windows. The whole would have been covered with stone slabs, and would have been surrounded by eight groups of pinnacles, most of which would no doubt have been twisted. Deeply though one must regret that this great chapel has been left unfinished and open to the sky, yet even in its incomplete state it is a treasure-house of beautiful ornament, and it is wonderful how well the more commonplace Gothic of Huguet's work agrees with and even enhances the richness of the detail which Fernandes drew from so many sources, late Gothic, early renaissance, and naturalistic, and which he knew so well how to combine into a beautiful whole. The great Claustro Real, built by Dom João I., was peculiar among Portuguese cloisters in having, or at least being prepared for, large traceried windows. Probably these had remained blank, and for about a hundred years awaited the tracery which more than any part of the convent shows the skill of Matheus Fernandes. There seems to be no exact record of when the work was done, but it must have been while additions were being made to the Imperfect chapels, though more fortunate than they, the work here was successfully finished. The cloister has seven bays on each side, of which the five in the middle are nearly equal, having either five or six lights. In the eastern corners the openings have only three lights, in the south-western they have four, and in the north-western there stands the square two-bayed lavatory. (Fig. 60.)
