The Comacines at this era were perfectly sincere and their façade was always a true face to the church. The eaves with the airy gallery of colonnettes beneath them followed the exact line of the low-pitched roof. It was only when they became eclectic, and their style got mixed and over-florid, that the false fronts such as we see at Lucca came in. The inward division of nave and aisle is faithfully marked on the outside by piers or pilasters. S. Michele has four pilasters dividing it into the three portions, each one supplied with its round-arched door. In the fifteenth century the central windows were altered and a large ugly round orifice was placed above the three Lombard ones. But in 1861 they had the good taste to open the original windows, indications of whose masonry were visible in the wall, and to add the cross, deep cut in the stone, which was a distinctive feature in façades of this era. Indeed the church may be taken as a type, in all its aspects, of the Romano-Lombard building. The most remarkable part is perhaps its ornamentation, which is unique and fanciful to the highest degree. Besides the carvings on door and window, the whole façade is striped with lines of sculptured stones, a queer mixture of angels, demons, saints, and monsters, that seems a nightmare dream of mediæval superstitions, but are really a mystic Bible in stone. I shall speak more fully of this in the chapter on Lombard ornamentation. [Illustration: FAÇADE OF SAN MICHELE AT PAVIA. UPPER PART RESTORED TO ITS ORIGINAL FORM; LOWER PART ANTIQUE. 7TH CENTURY. _See page 52._] We must now turn for a few moments to its history, on which great uncertainty rests. Some authors say that S. Michele at Pavia was built by Constantine the Great as a thank-offering for the aid given him by that Saint in his victory over the Franks in 325; but it is possible they may have confused this church with the one which Sozomenus asserts that Constantine erected to St. Michael on the banks of the Hellespont. Other writers, of whom Malaspina is one, claim it as an Ostrogoth foundation; others again, finding a suspicion of Arianism in the sculpture of the Annunciation on the south side of the church, assign it to Agilulf before his conversion from Arianism; while Gabriel Rosa, author of _Storia dei feudi e dei comuni in Lombardia_, attributes it to King Grimoald.
