octagon. These triangular spaces are roofed with elaborate wooden vaults, with carved and gilt ribs leaving spaces painted blue and covered with gilt ornament. Above the cornice the panelling rises perpendicularly for about eleven feet; there being on each cardinal side eight panels, in two rows of four, one above the other, and over each arch four more--forty-eight panels in all. Above this begins an octagonal dome with elaborately carved and gilt mouldings, like those round the panels, in each angle and round the large octagon which comes in the middle of each side. The next stage is similar, but set at a different angle, and with smaller and unequal-sided octagons, while the dome ends in one large flat eight-sided panel forty-five feet above the floor. All the space between the mouldings and the octagons is filled with most elaborate gilt carving on a blue ground. Nor does the decoration stop here, for the whole is a veritable Heralds' College for all the noblest families of Portugal in the early years of the sixteenth century. The large flat panel at the top is filled with the royal arms carved and painted, with a crown above and rich gilt mantling all round. In the eight panels below are the arms of Dom Manoel's eight children, and in the eight large octagons lower down are painted large stags with scrolls between their horns; lastly, in each of the forty-eight panels at the bottom, and of the six spaces which occur under each of the vaults in the four corners; in each of these seventy-two panels or spaces there is painted a stag. Every stag has round its neck a shield charged with the arms of a noble family, between its horns a crest, and behind it a scroll on which is written the name of the family.[101] The whole of this is of wood, and for beauty and originality of design, as well as for richness of colour, cannot be surpassed anywhere. In any northern country the seven small windows would not let in enough light, and the whole dome would be in darkness, but the sky and air of Portugal are clear enough for every detail to be seen, and for the gold on every moulding and piece of carving to gleam brightly from the blue background. None of the ceilings of later date are in any way to be compared in beauty or richness with those of these two halls, for in all others the mouldings are shallower and the panels flatter.
