The effect of the blazing sun pouring down on the façade at midday, casting deep shadows under the arches, is very fine. Again, in the evening when the domes are alight with the last rays of the dying orb and the great Piazza is in cool shade, the glories of the wonderful fabric assume a dramatic effect which becomes almost tragic as the light disappears and everything subsides into a monotone. Colour begets more subtlety in grey weather; every note that might jar on the eye is then diffused among the quieter tones around, and for this reason the pearly sky of a grey day was chosen to depict S. Mark's. The great _campanile_ which fell to the ground on July 14, 1902, is now in course of re-erection. For some years past the necessary but hideous hoarding at its base has interfered with the beauty of the Piazza. The illustration does not show this but depicts the length of the façade, with the beautiful Porta della Carta and corner of the Doge's Palace beyond.
The lowest portion of the façade is formed as a vestibule with seven arches, the last one of which at each end is open through. All the columns and their capitals (spoils from the East) are of much older date than the building. Very few of these capitals fit the _abacus_ on which they rest; most of them are exquisitely carved with foliage free from all imagery. The central arch is larger than the others. Under it is a grand door of forty-eight bronze panels inlaid with silver. The workmanship of the other doors which flank this is also very fine. The intricate Byzantine carving above these forms a scheme of decoration wherein figures, birds, beasts and arabesques run in a perfect riot of fanciful design. The vaulting of the vestibule is covered with mosaics of different periods. Those of the twelfth century are concerned with the Creation of the Firmament and the Creation of Life; the story of Adam and Eve continued on to the Deluge and Noah; the tragedy of Cain and Abel; Joseph's dream, Pharaoh and the story of Moses. The general scheme throughout is of white figures, mostly nude, on a green ground. Although not in any way comparable to the earlier mosaics at Ravenna, these are far better in style and true feeling for the enrichment of a flat surface than those of later date in the lunettes above the façade arches. Here the _raison d'être_ of mosaic has been made subservient to an attempt to imitate the shades and gradations of an oil painting. The most important of these later mosaics is that which was executed from a design by Titian by the brothers Zuccati in the sixteenth century, wherein S. Mark appears in pontifical robes. It is above the centre door. On the pavement beneath is a red and white lozenge of marble marking the spot where Pope Alexander III. and Barbarossa were reconciled in July 1177, through the intervention of the Venetian Republic. Many inscribed slabs of marble bearing legends in Greek and Syriac, and Roman bas-reliefs, are let into the walls of the vestibule, evidence of offerings towards the building of the fabric. All the archivolts of the five large arches are decorated with symbolic carvings; the most interesting being that of the main entrance, where a charmingly quaint story illustrative of peasant life in the twelve months of the year tells in a realistic way the labours of those who till the soil. February with a little figure sitting at a fire warming his hands is particularly naïve.
