The S. façade, looking as it does towards the Molo, would in olden times arrest the eye of the traveller as he entered the city. It is most lavishly decorated. The reliefs and marble facings towards the Porta della Carta are some of the finest that remain of the ancient basilica. Their lowly position seems to have preserved them from the restorer’s hand. At the angle is a rude Greek relief in porphyry, probably from Acre, of two pairs of armed figures clasping each other. They are said to represent Greek emperors who shared the throne of the East early in the eleventh century. In the foreground stand the two beautifully decorated marble door-posts brought from St Sabbas in Acre. They should, however, change places to occupy the relative position they formerly held in the church. Below the mosaic of the Virgin and Child in the smaller arch above the gallery two lamps burn nightly in perpetual memory of an act of injustice perpetrated by the Ten in 1611, when an innocent man, Giovanni Grassi, was executed. The short porphyry column at the S.W. corner is the old edict stone where the official notices and laws of the Republic were proclaimed to the people. [Illustration: CAPITALS, ATRIUM, S. MARCO] At our feet, as we enter the atrium by the main portal are three slabs of porphyry which mark the legendary, but not the actual, spot where the reconciliation of the Pope and the Emperor Barbarossa took place. The shafts and capitals of the columns in the atrium are among the richest in the basilica. The mosaics, designed to instruct and prepare the catechumen, illustrate Old Testament history, and for their simple beauty will repay perusal. [Illustration: I TRE PONTI.] In the south cupola are three concentric zones of mosaics which illustrate the six days of Creation, the Institution of the Sabbath, the Fall and the Expulsion from Eden. The number of the day is indicated by a corresponding number of angels standing beside the Creator with hands uplifted in praise. At the institution of the Sabbath the Lord is seen resting from His work with three angels on either side; the seventh kneels receiving the Lord’s blessing.[88] There is a quaint portraiture of the Lord clothing Adam and Eve,--Adam most uncomfortable, and Eve looking reproachfully at the ill-fitting garment. Five mosaics in the three lunettes under the cupola tell the story of Cain and Abel, and under the vaultings between the first cupola and the central vestibule is the story of Noah. On the W. side of the next vaulting is the story of the Tower of Babel. Below is the tomb of the Dogaressa Felicia, the young wife of Vitale Falier, who, as the inscription tells, was a true servant of God and of the poor, and who spurned luxury (_calcavit luxurium_).
