The cathedral is a recent building of no beauty. Two lions which once supported the columns of a Lombard doorway now carry the holy-water stoups; and in a passage near the sacristy is a carved, painted, and gilded rood of the twelfth century--a piece of furniture which is rarely found remaining in Italian churches. The grandest church in Bologna is undoubtedly San Petronio, which is well placed on one side of the Piazza Maggiore. It was not commenced until 1390, so that we must not be surprized to find the faults in detail which mark the period. But the general scheme of the church is so magnificent that these faults do not strike the eye at all offensively. As it stands even now, with only its nave and aisles finished, it gives a vast idea of size and space, though this is hardly appreciated at first, owing to the enormous dimensions, the fewness of the parts, and the extreme simplicity of all the details. The west front is of immense size and width, but its only finished parts are the plinth and doorways, the whole of the rest being left in rough brick. The detail of this finished part is of poor character, and later than the fabric. It is rather richly carved with figures, which are sometimes much praised, but which seemed to me (with the exception of a Pietà over the south-west doorway) to be of poor style and character. Going round to the side of the building, the design is of earlier date and much more interesting. The aisle-windows are noble designs of four-lights in each bay, separated by buttresses and surmounted by steep-pitched gables. The detail is an extremely good combination of brick and stone, whilst a magnificent plinth of stone and marble gives great force to the work. The transept was never built; but at the point where it was intended to be connected with the aisle, there is a curious conceit--a window at a projecting corner with half its arch and tracery facing south, and the other half facing west. It is, so far as I remember, a unique example in a church, but is just a little like the angle-windows in some of the Venetian palaces, though these never indulge in such an absurdity as is the construction of two halves of pointed arches over such an opening.
