Such is what the descendants of the sculptors preserved out of antiquity, such is what the human mind became in the chaos of the Tenth Century at the time of the Hungarian invasions, of Marozzia and Theodora: sad, mournful, anæmic, dislocated and mechanical figures, God the Father and six angels, three on one side and three on the other, all leaning at the same angle like a row of cards leaning against one another; the twelve apostles all in a row, six in front and six in the intervening spaces, like those round rings with holes for eyes and long lines for arms that children scribble in their exercise-books. On the other hand, the entrance doors, carved by John of Bologna,[12] are full of life: leaves of the rose, the grapevine, the medlar, the orange and the laurel with their berries, their fruits and their flowers, amongst which are birds and animals, twine about and make frames for animated figures and groups that are energetic and imposing. This wealth of truthful and vital forms is peculiar to the Sixteenth Century: it discovered nature and man at the same time. Five centuries lie between the work of these two doors. There is nothing more to say about the Baptistery or the Leaning Tower; the same idea, the same taste and even the same style are seen in them. The one is a simple isolated dome; the other is a cylinder; each has its exterior decoration of columns. However, each has its own distinct and speaking physiognomy; but too much time would be occupied in either talking or writing about them and too many technical terms would be needed to distinguish the subtle differences. I will only mention the inclination of the Tower. It is supposed that when the Tower was half-finished, it leaned and that the architects kept on, and since they went on with it this inclination did not seem to have troubled them. At all events, there are other leaning towers in Italy,--at Bologna, for instance; voluntarily, or involuntarily, this fondness for oddity, this search for paradox and this yielding to fantasy, is one of the characteristics of the Middle Ages.
