The arches of the porches are supported by piers, completely broken and surrounded by columnar shafts and niches carrying statues on their corbels. These piers stand out free from the jambs of the doors and wall surfaces behind, and thus form an open gallery between the two. Around and over all is an astounding and lavish profusion of sculpture,--no less than forty statues. The jambs and splays, the shafts, the archivolts, the moldings and tympanums are covered with carving, varied and singularly interesting in the diversity of its period and character. Part of it is late Byzantine with the traditions of the twelfth century, while much is from the very best vigorous Gothic chisels, and yet some, later Gothic. Certain borders, leafage, and vine branches are Byzantine, and so also are some of the statues, "retaining the shapeless proportions and the immobility and parched frown of the Byzantine School, so perfectly dead in its expression, offering, however, by its garb and by its contours not a little to the study of this art, and so constituting a precious museum." Again, other statues have the mild and venerable aspect of the second period of Gothic work. The oldest are round the most northerly of the three doorways. Every walk of life is represented. There is a gallery of costumes; and most varying emotions are depicted in the countenances of the kings and queens, monks and virgins, prelates, saints, angels, and bishops. Separating the two leaves of the main doorway, stands Our White Lady. But if the statues are interesting, the sculpture of the archivolts and the personages and scenes carved on the fields of the tympanums far surpass them. Mrs. Wharton says somewhere, "All northern art is anecdotic,--it is an ancient ethnological fact that the Goth has always told his story that way." Nothing could be more "anecdotic" than this sculpture. The northern tympanum gives scenes from the Life of Christ, the Visitation, the Nativity, the Adoration of the Magi, and the Flight into Egypt. In the southern, are events from the life of the Virgin Mary; but the central one, and the archivolts surrounding it, contain the most spirited bits. The scene is the Last Judgment, with Christ as the central figure. Servants of the Church of various degrees are standing on one side with expressions of beatitude nowise clouded by the fate of the miserable reprobates on the other. In the archivolts angels ascend with instruments and spreading wings, embracing monks or gathering orphans into their bosoms, while the lost with horrid grimaces are descending to their inevitable doom. Not even the great Florentine could depict more realistically the feelings of such as had sinned grievously in this world.
