By the beginning of the eleventh century this had been much ruined by the Saracens and others, and Desiderius its abbot, in 1066, decided to restore it. He was of the race of the Lombard Dukes of Beneventum, was a friend of Pope Gregory VII., and became his successor on the papal throne under the name of Victor III. Desiring that his church should be a very "majestic temple," he sent to call artificers from Amalfi and from Lombardy.[88] Among the Italians was a certain Andrea, from Serra di Falco, near Como, a fine worker in metal, who, with his disciples, made the bronze doors. Some interesting baptisteries were erected in the tenth century by the Comacines. The baptistery at this time seems to have had a set form--the octagon; and a mystical significance, that figure being highly symbolical of the Trinity, being formed by a conjunction of three triangles. In the earlier days of the Romano-Lombard style, the baptistery generally had only a small arcade, or row of brackets supporting arches round the outer wall beneath the roof, and a practicable gallery round the interior. Of this shape was the Florentine Baptistery, that of Como and many others. When the later Comacines worked in more florid Romanesque style, the Baptisteries were often covered with little galleries or rows of colonnettes like those of Pisa, Parma, Lucca, etc. A fine specimen of Lombard work of about 1000 A.D., or a little later, which shows the approach towards a more Gothic style, may be seen in the cloister of Voltorre, a little walled town on Lake Varese. The cloister of Voltorre is thus described--"The beauty of this eleventh-century Lombard building is singular. The four sides are formed of porticoes which sustain the upper storey. The porticoes facing the open court are formed on one side of small graceful arches in brick, with friezes and reliefs sustained by elegant colonnettes, some round and some octangular, with capitals of various forms. On two other sides the colonnettes are smaller and shorter, but still graceful; they terminate in varied and bizarre capitals surmounted by a kind of bracket on which the large stones of the upper building rest. Among the sculptures of the little columns on the left as one enters the court, is incised in mediæval characters and abbreviations the following--'_Lanfrancus magister filius Dom. Ersatii de Livurno_.'" Livurno most probably stands for Ligurno, a place a few miles from Voltorre. So our master Lanfranco Ersatti, having graduated in the Comacine Guild, set himself to embellish his native place. In 1099 Magister Lanfranco designed the Duomo of Modena, which, as will be seen hereafter, was the work of centuries, he being followed by a long series of architects.
