The solidity with which these churches were built, and the general narrowness of their proportions as compared with the domical churches of the same time and district, enabled the architects occasionally to attempt some splendid erection on the intersection of the nave and transepts, which is the spot where height should always be aimed at. The dome at Cruas, in the Provençal district, has already been described (Woodcut No. 558). The church at Conques has one as important, though dissimilar; but the finest is that of St. Sernin at Toulouse (Woodcut No. 578), which rivals the design of our spires at Salisbury, Norwich, and elsewhere, but its height being only 230 ft. from the ground, it cannot be compared with them in that respect. The 3 lower storeys only are of the age of the church; the 2 upper were added long afterwards, but were adapted with remarkably good taste. Though differing in design and detail, their general form and outline is such as to accord most happily with the older structure on which they are placed; there is nevertheless a sameness of design in placing so many similar storeys one over the other, merely diminishing in size, which is not altogether pleasing. The general effect, however, is good, and for a central object it is, if not the finest, certainly one of the very best which France possesses. [Illustration: 578. St. Sernin, Toulouse. (From Taylor and Nodier.)] As in all French styles, the western façades of the Southern churches are the parts on which the architects lavished their ornaments with the most unsparing hand. Generally they are flat, and most of them now terminate squarely, with a flat line of cornice of slight projection. Beneath this there is generally a range of arches filled with sculpture or intended to be so—the central one, and that only, being used as a window. Beneath this is the great portal, on which more ornament is bestowed than on any other feature of the building. Some of these gateways in this province, as in Provence, are wondrous examples of patient labour, as well as models of beauty. They possess more than the richness of our own contemporary Norman portals, with a degree of refinement and delicacy which our forefathers did not attain till a much later age. Some of these church-portals in Aquitaine are comparatively simple, but even they make up for the want of sculpture by the propriety of their design and the elegance of their composition.
