Coming last of all to the greatest wonder of the Piazza, it is really with surprise you find the Campanile so beautiful, perhaps the most beautiful tower of Italy. It is like a lily leaning in the wind, it is like the slanting horn of an unicorn, it is like an ivory Madonna that the artist has not had the heart to carve since the ivory was so fair. Begun in 1174, it was designed by Bonannus. He made it all of white marble, which has faded now to the colour of old ivory. Far away at the top of the tower live the great bells, and especially La Pasquareccia,[61] founded in 1262, stamped with a relief of the Annunciation, for it used to ring the Ave. I think there can be no reasonable doubt that the lean of the Tower is due to some terrible accident which befell it after the third gallery had been built, for the fourth gallery, added in 1204 by Benenabo, begins to rectify the sinking; the rest, built in 1260, continues to throw the weight from the lower to the higher side. As we know, the whole Piazza was a marsh, and just as the foundations of the Tower of S. Niccolo have given a little, so these sank much earlier, offering an unique opportunity to a barbarian architect. There is, as has been often very rightly said, no such thing as a freak in Italian art: its aim was beauty, very simple and direct; nowhere in all its history will you find a grotesque such as this. It is strange that a northerner, William of Innspruck, finished the Tower the fifth storey in 1260; and it may well be that this Teuton brought to the work something of a natural delight in such a thing as this, and contrived to finish it, instead of beginning again. It seems necessary to add that the tower would be more beautiful if it were perfectly upright.
