This dining-room projects somewhat to the west so as to leave space for a window looking south to the mountains, and one looking north across a small court, as well as one looking west. Of these, the two which look south and west are like each other, and like the other of Dom João's time except that the arches are not cusped; that the outer frame is omitted and that the abaci are moulded in front as well as at the ends; but the third window looking north is rather different. The framing has regular late Gothic bases, the capitals of the shafts are quite unlike the rest, having one large curly leaf at each angle, and the moulding running up the centre between the arches--which are not cusped--is plaited instead of being plain. Altogether it looks as if it were later than Dom João's time, for it is the only window where the capitals are not of the usual Arab form, and they are not at all like some in the castle of Sempre Noiva built about the beginning of the sixteenth century. The wall-tiles of the dining-room are like those of the Sala das Sereias, but end in a splendid cresting. The ceiling is modern and uninteresting. Next to the north comes the servery, a room without interest but for its window which looks west, and is like the two older dining-room windows. Returning to the Sala das Sereias, a spiral stair leads down to the central pateo, which can also be reached from the porch in the south-west corner. All along the south side runs the tank made by Dom João for his daughter's swans, and on three sides are beautiful white marble windows. At the east end of the north side three open arches lead to the bathroom. As is the case with the windows, the three arches are enclosed in a square frame. The capitals, however, are different, having an eight-sided bell on which rests a square block with a bud carved at each angle, and above an abacus, moulded all round. The arches are cusped like the windows, but are stilted and segmental. Inside is a recess framed in an arch of Dom Manoel's time, and from all over the tiled walls and the ceiling jets of water squirt out, so that the whole becomes a great shower-bath, delightful and cooling on a hot day but rather public. In the middle of the pateo there stands a curious column--not at all unlike the 'pelourinho'[95] of Cintra--which stands in a basin just before the entrance gate. This column is formed of three twisted shafts on whose capitals sit a group of boys holding three shields charged with the royal arms. All round the court is a dado of white and green tiles arranged in an Arab pattern.
