It will be remembered that the tomb-house begun by Dom Duarte took the form of a vast octagon some seventy-two feet in diameter surrounded by seven apsidal chapels—one on each side except that towards the church—and by eight smaller chapels between the apses. When Matheus Fernandes began his work most of the seven surrounding chapels were finished except for their vaulting, but not all, as in two or three the outer moulding of the entrance arch is enriched by small crosses of the Order of Christ, and by armillary spheres carved in the hollow; while the whole building stood isolated and unconnected with the church.
The first thing, therefore, done by Matheus was to build an entrance hall or pateo uniting the octagon with the church. Unless the walls of the Pateo be older than Dom Manoel's time it is impossible now to tell how Huguet, Dom Duarte's architect, meant to connect the two, perhaps by a low passage running eastwards from the central apse, perhaps not at all.
The plan carried out by Matheus took the form of a rectangular hall enclosing the central apse and the two smaller apses to the north and south, but leaving—now at any rate—a space between it and the side apses. Possibly the original intention may have been to pull down the two side apses, and so to form a square ambulatory behind the high altar leading to the great octagon beyond; but if that were the intention it was never carried out, and now the only entrance is through an insignificant pointed door on the north side.
The walls of the Pateo with their buttresses, string courses and parapet are so exactly like the older work as to suggest that they may really date from the time of Dom Duarte, and that all that Matheus Fernandes did was to build the vault, insert the windows, and form the splendid entrance to the octagon; but in any case the building was well advanced if not finished in 1509, when over the small entrance door was written, 'Perfectum fuit anno Domini 1509.'
Two windows light the Pateo, one looking north and one south. They are both alike, and both are thoroughly Manoelino in style. They are of two lights, with well-moulded jambs, and half-octagonal heads. The drip-mould, instead or merely surrounding the half octagon, is so broken and bent as to project across it at four points, being indeed shaped like half a square with a semicircle on the one complete side, and two quarter circles on the half sides, all enriched by many a small cusp and leaf. The mullion is made of two branches twisting upwards, and the whole window head is filled with curving boughs and leaves forming a most curious piece of naturalistic tracery, to be compared with the tracery of some of the openings in the Claustro Real. ([Fig. 58].)
No doubt, while the Pateo was being built, the great entrance to the Imperfect chapels, one of the richest as well as one of the largest doorways in the world, was begun, and it must have taken a long time to build and to carve, for the lower part, on the chapel side especially, seems to be rather earlier in style than the upper. The actual opening to the springing of the arch measures some 17 feet wide by 28 feet high, while including the jambs the whole is about 24 feet wide on the chapel, and considerably more on the Pateo side,—since there the splay is much deeper—by 40 feet high. To take the chapel side first:—Above a complicated base there is up the middle of each jamb a large hollow, in which are two niches one above the other, with canopies and bases of the richest late Gothic; on either side of this hollow are tall thin shafts entirely carved with minute diaper, two on the inner and one on the outer side. Next towards the chapel is another slender shaft, bearing two small statues one above the other, and outside it slender Gothic pinnacles and tabernacle work rise up to the capital. Up the outer side of the jambs are carved sharp pointed leaves, like great acanthus whose stalk bears many large exquisitely carved crockets. On the other side of the central hollow the diapered shaft is separated from the tiers of tiny pinnacles which form the inner angle of the jamb by a broad band of carving, which for beauty of design and for delicacy of carving can scarcely be anywhere surpassed. On the Pateo side the carving is even more wonderful.[121] There are seven shafts in all on each side, some diapered, some covered with spirals of leaves, one with panelling and one with exquisite foliage carved as minutely as on a piece of ivory.
Between each shaft are narrow mouldings, and between the outer five four bands of ivy, not as rich or as elaborately undercut as on the chapel side, but still beautiful, and interesting as the ivy forms many double circles, two hundred and four in all, in each of which are written the words 'Tãyas Erey' or 'Tãya Serey,' Dom Manoel's motto. For years this was a great puzzle. In the seventeenth century the writer of the history of the Dominican Order in Portugal, Frei Luis de Souza, boldly said they were Greek, and in this opinion he was supported by 'persons of great judgment, for "Tanyas" is the accusative of a Greek word "Tanya," which is the same as region, and "erey" is the imperative of the verb "ereo", which signifies to seek, inquire, investigate, so that the meaning is, addressed to Dom Manoel, seek for new regions, new climes.' Of course whatever the meaning may be it is not Greek, indeed at that time in Portugal there was hardly any one who could speak Greek, and Senhora de Vasconcellos—than whom no one has done more for the collecting of inscriptions in Portugal—has come to the very probable conclusion that the words are Portuguese. She holds that 'Tãyas erey' or 'Tãya serey' should be read 'Tanaz serey,' 'I shall be tenacious'—for Tanaz is old Portuguese for Tenaz—and that the Y is nothing but a rebus or picture of a tenaz or pair of pincers, and indeed the Y's are very like pincers. In this opinion she is upheld by the carving of the tenacious ivy round each word, and the fact that Dom Manoel was not really tenacious at all, but rather changeable, makes it all the more likely that he would adopt such a motto.
The carvers were doubtless quite illiterate and may well have thought that the pincers in the drawing from which they were working were a letter and may therefore have mixed them up to the puzzling of future generations.[122] Or since nowhere is 'Tayaz serey' written with the 'z' may not the first 'y' be the final 'z' of Tanaz misplaced?
The arched head of the opening is treated differently on the two sides. Towards the Pateo the two outer mouldings form a large half octagon set diagonally and with curved sides; the next two form a large trefoil. In the spandrels between these are larger wreaths enclosing 'Tanyas erey,' which is also repeated all round these four mouldings.
The trefoils form large hanging cusps in front of the complicated inner arch. This too is more or less trefoil in shape,
