[Illustration: 517. Campanile, Palazzo Scaligeri, Verona. (From Street.)] Its whole height is about 315 ft., of which less than 200 are taken up in the square part—which thus bears a less predominant proportion to the spire than any other Italian example. It is evidently meant to rival the famous German spires which had become such favourites in the age in which it was built; and although it avoids many of the errors into which the excessive love of decoration and of _tours de force_ led the Germans, still the result is far from satisfactory. The change from the square to the octagon is abrupt and unpleasing, and the spire itself looks too thick for the octagon. Everywhere there is a want of those buttresses and pinnacles with which the Gothic architects knew so well how to prepare for a transition of form, and to satisfy the mind that the composition was not only artistically but mechanically correct. The Italians never comprehended the aspiring principle of the Gothic styles, and consequently, though they had far more elegance of taste and used better details, their works hardly satisfy the mind to a greater extent than a modern classical church or museum. The same remarks apply to the towers of Siena, Lucca, Pistoja, and indeed to all in the North of Italy: all have some pleasing points, but none are entirely satisfactory. None have sufficient ornament, or display enough design, to render them satisfactory in detail, nor have they sufficient mass to enable them to dispense with the evidence of thought, and to impress by the simple grandeur of their dimensions. [Illustration: 518. Campanile, S. Andrea, Mantua. (From Street.)] The towers of Asti (1266) and Siena (rebuilt in 1389) are illustrated in Woodcuts Nos. 493 and 498. They certainly display but little art. A more pleasing specimen is the tower (Woodcut No. 515) attached to the Duomo at Prato (about 1312), which may be considered as a specimen of the very best class of Italian tower-design of the age, although in fact its only merit consists in the increase in the size of the openings in every storey upwards, so as to give a certain degree of lightness to the upper part. On this side of the Alps the same effect was generally attained by diminishing the diameter. When a spire is to be added, that is the only admissible mode; but when the building is to be crowned by a cornice, as at Prato, the mode there adopted is perhaps preferable.
