At the back of the high altar is the Pala d'Oro, the greatest treasure the cathedral possesses, and the most celebrated golden altarpiece in existence. The upper part came from Constantinople in 976, the lower about the middle of the fourteenth century. It is composed of eighty-three panels of Greek and Byzantine design filled with enamelled figures, studded with uncut gems and precious stones, and covered with Greek and Latin inscriptions. More gorgeous than that of S. Ambrogio in Milan, this magnificent piece of goldsmith's art glitters and sparkles in a wonderful manner when lit up by the candles used at high mass, and is without doubt the most splendid ecclesiastical treasure in Italy.
The fifth or eastern dome which is over the presbytery is covered with mosaics representing Christ and the Prophets, and one that is hardly visible of S. Mark is on the walls of the east end. The great figure of Christ faces the church and in its simplicity is very impressive.
The gallery, which is where the triforium would be in a Gothic building, runs round the whole cathedral and is pierced on its inner side only. The walls at the back and above are decorated with more mosaic work dealing with acts of martyrdom, and the Translation and Recovery of the Body of the Lord. When stray beams of sunlight find their way through the openings in the domes and pass along the gold background, lighting up in odd places small portions of these wonderful tesseræ pictures, the effect is very beautiful. All the angles of this mosaic work are rounded off and the travelling rays glinting first on one golden corner, then on another, are strangely attractive to eyes accustomed to the greater architectural severity of a northern clime. The well-chosen slabs that line the lower portions of the cathedral walls have taken to themselves a sombre, dusky hue, a pale velvety brown, but there can be no doubt that in their pristine state they realised in their splendour the Venetian's love of colour.
The strange pulpit, which with part of the rood screen seen in the illustration stands to the north of the steps leading into the presbytery, is arranged in a double tier, and is entered by a double winding stair from the vestibule of the Capella de S. Pietro. Its curious domed sounding-board is very reminiscent of the East. Mention has already been made of the chapels of the Miraculous Virgin and S. Leonard. That dedicated to S. Peter is behind this pulpit on the north side of the presbytery. It has a door leading out into the piazza. The corresponding chapel to the south is dedicated to S. Clement. At the end of the north transept is another to S. Isidore—a dark, solemn little place. The sacristy is beyond the chapel of S. Peter at the back of the presbytery. It is a fine apartment with mosaics from designs by Titian and his pupils, which may be studied as a good example of Renaissance decoration in tesseræ. Sansovino, who executed the beautiful door, is said to have had it in hand for twenty years.
The baptistery is entered from the south aisle, and with the adjoining Cappella Zeno is one of the most interesting parts of S. Mark's. In the former is the monument and sarcophagus of Doge Andrea Dandolo, who died in 1354. It is a grand specimen of the sculpture of the age. The recumbent figure of the Doge, who was the last to be buried in S. Mark's, is very serene in its realisation of the Last Sleep. All the mosaics the chamber contains were given and paid for by Andrea. Most of them naturally relate to the Holy Rite. The font is very ancient, and has a fine bronze cover designed by Sansovino and surmounted by a statuette of S. John the Baptist. A very beautiful low relief of four crossed swords which compose a cross, with birds beneath, is let into one of the walls. On the vaulted roof of the Cappella Zeno, the life of the Evangelist, whose body at first rested here, is well depicted in a series of mosaics. The centre of the chapel is occupied by the tomb of Cardinal Zeno, who left the bulk of his immense fortune to S. Mark's. The altar stands under a bronze canopy covering figures of Our Lady (who wears a gilded shoe), S. Peter, and S. John the Baptist. The legend runs that the Virgin gave her bronze shoe once to a poor votary and it was immediately turned into gold. From this incident the chapel, which became the Cardinal's Mausoleum, is also known as that of the Madonna della Scarpa.
Venice possesses nearly seventy churches, but of these only the two most celebrated can be mentioned in this chapter. They are SS. Giovanni e Paolo, and the Frari. The former had its origin in the great preaching Order of S. Dominic, and the latter in that of S. Francis. These saints, bound by vows of poverty, went forth preaching humility, and so great a meed of success did they attain, that we find throughout the country, as a result of their crusade, huge churches like these built to hold large congregations. In Venice both Orders had their following among different patrician families, who were mainly responsible for the monetary assistance the Orders received, and who therefore acquired a sort of prescriptive right to burial space within the holy walls they had helped to raise. For this reason the tombs we find in SS. Giovanni e Paolo and the Frari are not only an epitome of the rulers of Venice, but in them can be traced from the earliest Gothic the different styles of Venetian decorative art as exemplified in her sepulchral monuments.
SS. Giovanni e Paolo is a fine brick building of early Italian Gothic, which was commenced in 1246 and finished in 1390. Its length is three hundred and thirty feet, its width at the transepts one hundred and forty-three, and in the nave ninety-one feet. From this it will be seen that the transepts are short. The spacious nave has five bays, the arches of which are supported by single columns of grey stone with simple floral capitals. The vaulting, as is usual in Italian Gothic, is low. The galleried triforium has small outlets into the church, and a clerestory of pointed lights in groups of three has taken the place of much larger single windows. The aisles are narrow. The apsidal choir is architecturally very striking. From a few feet above the floor rise the long narrow windows of the apse reaching up beyond the base of the vaulting and giving an idea of immense height. The glass they contain is, however, very crude; and, unfortunately, a terrible pink wash covers the walls, so pink that the beauty of the architectural features is considerably marred. The choice of material and the selection of colour has more to do with the success or failure of a building than is generally realised. The transepts, nave, and aisles are coloured grey, and harmonise with the stone columns mentioned above, and with the monuments of faintly tinted marble which crowd the walls of the aisles.
Among the most notable tombs are those of the Mocenigo family, a family which possessed the whole of the west wall of the church, and whose monuments almost cover it. Of the three equestrian tombs that are in the church, pride of place must be given to the one put there to Niccolo Orsini, who commanded the Republic's forces in the war against the League of Cambray. The gilded group of the general and his horse above the sarcophagus is full of life and vigour. The simple but very beautiful tomb of Paolo Loudan, on which his recumbent figure in full chain mail lies stretched, is a fine work of the middle of the fourteenth century.
The grand monument to Andrea Vendramin, who died in 1478, and who was the first of the new nobility to be elevated to the position of sovereign, is the most refined example of a Renaissance tomb in Venice. The Doge lies, with face turned towards the spectator, on a couch supported by eagles. Behind him are pages and other attendants. The carving and arabesques of the canopy and its supports, into which notes symbolical of naval power are crowded, though extremely intricate, are very pure in style. In the lunette beneath the arch kneels the Doge, who is being recommended to Our Lady by S. Mark. Opposite to this beautiful tomb is the Gothic memorial to Doge Michele Morosini, who died in 1382. The background of the central portion is a good mosaic of the Crucifixion, in front of which the aquiline features of the recumbent Duke are very prominent. The niches on either side are filled with figures of different saints, and the whole is surmounted by S. Michael with the Dragon.
