The building is a simple parallelogram, 31 feet 5 inches wide, by 76 feet in length. The lower portion of the side walls is quite unornamented for 20 or 25 feet in height; but above this is very richly adorned with plaster-work. There is, first, a broad band of foliage, with Hebrew inscriptions above and below it, and above this on each side an arcade of nineteen arches, springing from coupled shafts, eight of its divisions being pierced and filled with very elaborate lattice-work. The end wall (now the altar end) has a very slight recess in the centre, and the whole of it to within some seven feet of the floor is covered with rich patterns, inscriptions, and coats of arms, whilst above the arcade is continued on from the side walls in eight divisions. The arcades are all cusped in the usual Moorish fashion, the outline of the cusps being horseshoe, but without an enclosing arch. The end opposite to the altar has two windows pierced in the upper arcade, and three windows below breaking up into the band of foliage and inscriptions. The whole is now whitewashed, and though the detail is all fantastic and overdone, the effect is nevertheless fine, owing to the great height of the walls and to the contrast between the excessive enrichment of their upper and the plainness of their lower part. The Retablo over the principal altar is a work of the end of the fifteenth century, but not of remarkable merit, having paintings of Scripture subjects under carved canopies; there is another of the same class against the north wall. The roof is a grand example of the Moorish “_artesinado_”[216] work. It has coupled tie-beams, and a deep cornice, which is carried boldly across the angles, so as to give polygonal ends to the roof, which is hipped at the ends, the rafters sloping equally on all four sides. These rafters are only introduced to improve the appearance of, and--it may be--the possibility of hearing what was read in, the synagogue. The pitch of the real roof is very flat, and where a flat roof is absolutely necessary, this kind of ceiling is undoubtedly very effective. At some height above the plate the sloping rafters are stopped by a flat ceiling below the collar rafters, panelled all over in the ingeniously intricate geometrical figures of which the Moorish architects were so fond, and in the device of which they were always only too ingenious. The rafters as well as the tie-beams are used in pairs placed close to each other, and the space between them is divided into panels by horizontal pieces at short intervals, with patterns sunk in the panels. There is a western gallery, and some seats made of glazed encaustic tiles on each side of the sanctuary. The exterior has arcades answering to those of the interior: it is built mainly of brick, with occasional bands of rough stonework. The bricks are 11 in. by 7¾ in. by 1¼ in. in size, and are used with a mortar joint 1¼ in. in thickness.
