The south transept façade is, after the lantern, the most interesting part of the church. Its general character is extremely peculiar, and unlike any other work I have seen in Spain. There are plain buttresses at the angles, and the space between them is divided into three compartments by fluted pilasters, which rise as far as the corbel-table (continued at the same level as the eaves-cornice), and carry three pointed arches which are fitted to the original flat-pitched gable, the centre arch being the widest and highest. The centre compartment has a doorway with three shafts in each jamb, and four orders in the arch all alike, and resembling the door in San Martin, at Salamanca, illustrated at p. 91. The effect of light and shade in this ornamentation is very great; and, executed as it is with comparatively little labour, I rather wonder not to have seen more of the same work elsewhere. Two small recessed arches occupy the side compartments of the façade on either side of the doorway: that on the right hand has its archivolt carved with extreme delicacy with a small leaf repeated frequently; and both have within their arches sculptures of figures. The bases of all the columns are fluted, and the capitals are all carved rather rudely, and have heavy abaci. Over the side arches are square sunk compartments enclosing circular ornaments carved with a succession of hollow flutings sinking back to the centre. In fact, these strange ornaments--which at first sight look almost like modern insertions--are precisely like models of the dome with its arched groining spaces between the ribs. Above the doorway is a row of five arches recessed in the wall,[104] and under the central arch in the gable is a blocked-up window-opening. I was unable to gain admission to the interior of the steeple. On the outside it rises in a succession of nearly equal stages, of which the upper three have, in the common Lombard fashion, windows of one, two, and three lights respectively.
