The part the Comacines had in forging the connecting chain between the Tuscan Renaissance and the classic Roman, and the artistic pedigree of Niccolò Pisano, who is the first link in that branch of the threefold chain, will be traced in a future chapter. We must now inquire how the first Romano-Lombard style of the Comacines, from the sixth to the tenth centuries, became changed into the florid Romanesque, in which the same guild was building in all parts of Italy from the twelfth to the fifteenth centuries. This development was possibly derived from both Northern and Southern sources. The close connection of the Comacine or Lombard architects with the Patriarch of Aquileja in the seventh and eighth centuries brought them in touch with the Greek artists of the earlier period, from whom they learned much, especially in varying the plan of their circular churches, and in richness of ornamentation. Their later emigrations to the southern Lombard dukedoms, and their work in Sicily had a still greater effect on them. It seemed to break up their fixed traditions as a thaw breaks up ice. Before this time, every church must be of a fixed plan; every apse round; every space of wall headed by a gallery or arched brackets; every arch a pure half-circle on colonnettes. But the varied arches of the Oriental-Saracenic style influenced their fancy; they saw that art lay in variety, and learned that the pointed arch was as strong as the round one, the ogival arch more graceful. The Moorish arch never entirely took their fancy, though they sometimes gave a slight Moorish curve to their stilted arches. It must be remembered that the _Magistri_ of the Comacine Guild were no longer of the same calibre as those mediæval men who built for the Longobards. Those were the products of an age of slavery and degeneration, who, lacking literature, clung to tradition, and could only act according to the small portion of intellectual light vouchsafed to the Dark Ages. They put stone and stone together, precisely as their forefathers had taught them. In form they clung to their ancient teacher, Vitruvius, and for their ornamentation to their ancient pagan superstitions, grafted on a mystical Christianity. Yet, as we have seen, they so far improved on these, as to build several Basilican churches which might be called grand for the time, though still holding close to traditional forms. The Comacine after A.D. 1000 was a man beginning to feel his intellect; the feudal system was breaking up, republics beginning to be established, schools were opened, and man began to feel himself no longer a vassal bound hand and foot, but a human being who might use his own intellect for his own pleasure and good. What wonder then, that the arts began to flourish, commerce to increase, and riches to accrue in this joyous freedom? And what wonder that man's thankfulness for freedom first took the form of building churches for the glory of the God of the free?
