The architectural portion of the interior may be first of all described. The apse is simply a sanctuary, and the chancel is formed by marble screens on each side of the nave, leaving a broad entrance-way between them, and enclosing about one-third of its length. Against the west side of these screens are altars, each with a small carved marble reredos; whilst on the east of them are steps leading to the two ambons; that on the north being a book-rest, carved in marble, and fixed with its face to the east; that on the south of iron, and turning upon a pivot. Between these screens and the sanctuary arch are modern stalls on each side. The sanctuary has seats all round the apse (except in the eastern bay), each with a delicate white marble canopy. The sacristy is groined, and has a thirteenth-century press of wood of a design rather curious than beautiful, but very rich in its detail. In the nave, as I have already said, walls have neither cornices nor string-courses to break their even surfaces, and their face is continued on in semicircular waggon vault. There are six lancet windows on the south, none at all on the north, and a three-light window very high up in the gable at the west end above the doorway. The architectural merit of the building is simply, I think, that it performs satisfactorily the office of giving ample unbroken surfaces of wall for paintings. The arrangement of these is very regular. The vault is divided into two parts by wide coloured borders, the space between which is painted blue, powdered with gilt stars, and in each bay there are five small medallions with figures on a gold ground. The side walls are divided by borders into three divisions in height; the upper division containing subjects from the life of the Blessed Virgin; the central, those illustrative of the life of Our Blessed Lord; whilst those nearest to the ground are representations of the Virtues and Vices opposed to each other; the last division tinted only in one colour, the others richly painted in bright colours upon a field of blue.
