The tympanum is sculptured with our Lord in an aureole in the centre, the Betrayal and the Last Supper below, angels censing on either side, and the Coronation of the Blessed Virgin above. The orders of the archivolt are filled with figures, some representing the resurrection of the dead, and others figures of kings and saints worshipping the central figure of our Lord. The door-opening has the peculiarity of having an elliptical or three-centred arch. This feature I noticed also in doors evidently of about the same age at Burgos and at Leon, and it is just one of those evidences which go surely to prove that the several works are all designed by the same architect. The resemblance of the mouldings in the jamb of this doorway to those in the western end of Leon Cathedral is very close, and all these doors have an order of very similar foliage between the several sculptured or storied orders of the archivolt. I do not think the work here is quite as good as that at Leon, though the filling in of the tympanum with a well-marked vesica in the centre, and four rows of subjects divided by well-defined horizontal lines, is uncommonly good. A sort of shallow porch has been formed by some later groining, which occupies the space between the buttresses on either side of the doorway, and this is finished in front with a rich open traceried parapet and pinnacles. It was during the prelacy of Don Sancho III., Bishop of Avila from A.D. 1292 to 1353, that most of the later works of the cathedral were executed, and his arms are sculptured upon the vault of the Crossing. The character of all the work would agree perfectly with this date, which is given by Gil Gonzalez Dávila[174] in his account of the church. [Illustration: Roofing, Avila.]
