In the little chapel of the Madonna dei Mascoli at the W. angle of the N. transept, where of old a guild of men used to assemble, are some fine fifteenth-century mosaics by Michele Giambono. They are unhappily injured by restoration, but in the main the early Renaissance feeling has been preserved and the more natural modelling of the figures and fuller architectural detail form a pleasing contrast to the stiff and sometimes hard design of the Byzantine workmen. East of this is the richly decorated chapel of St Isidore founded by the same Doge and scholar who decorated the Baptistery. The work was not, however, completed until 1355 under Dom. Gradenigo. The inscription over the altar tells that the body of the Blessed Isidore was brought from Chios in 1125 by Doge Dom. Michiel and now rests in the tomb below. The sculptured figure of the saint and the reliefs to left and right representing his martyrdom are fine work. The fourteenth-century mosaics so faithfully wrought by the artists of that great epoch have needed but slight repair and remain practically as they left them. Over the altar is Christ seated between S. Mark and Isidore, and balancing this at the opposite end are the Virgin and Child, the Baptist and St Nicholas. The legend of the saint is illustrated on the walls. In this chapel we are standing within part of the actual fabric of the old church of St Theodore. When the S. wall of the chapel was peeled in 1832 it was found to be blackened by exposure to the weather and pierced by a window with an iron grille. The group of worshippers ever before the altar to the left as the visitor leaves this chapel will tell him that he is approaching the shrine of the Virgin. Under a canopy is the miraculous Nicopeian icon of the Virgin which was captured from Murzuphles and formed part of the spoil of Constantinople. Doge Dandolo sent it to Venice in a specially appointed ship, and in 1618 the present altar was raised by Doge Giov. Bembo. The image (only exposed on Saturdays) was traditionally painted by St Luke. It is lavishly decorated with precious stones and surrounded by ex-votos. Passing the altar of St Paul, bearing a statue of the saint and a fine relief of the scene of his blindness, the chapel of St Peter is reached. In front is a screen with statues of the Virgin and Child and four women saints, the Massegne. In the apse of this chapel is the entrance to the Sacristy, one of the most beautiful chambers in Europe. The magnificent mosaic ceiling designed by Titian and wrought with perfect art; the rich marble decorations; the symmetry and proportion of the architecture; the chastened glow of colour will not fail to impress the spectator.
