is no longer to be seen, and is conjectured by Corner, with much probability, to have perished "in qualche ristauro."] according to Sansovino and the author of the "Chiesa Ducale di S. Marco," in 1094 according to Lazari, but certainly between 1084 and 1096, those years being the limits of the reign of Vital Falier; I incline to the supposition that it was soon after his accession to the throne in 1085, though Sansovino writes, by mistake, Ordelafo instead of Vital Falier. But, at all events, before the close of the eleventh century the great consecration of the church took place. It was again injured by fire in 1106, but repaired; and from that time to the fall of Venice there was probably no Doge who did not in some slight degree embellish or alter the fabric, so that few parts of it can be pronounced boldly to be of any given date. Two periods of interference are, however, notable above the rest: the first, that in which the Gothic school had superseded the Byzantine towards the close of the fourteenth century, when the pinnacles, upper archivolts, and window traceries were added to the exterior, and the great screen, with various chapels and tabernacle-work, to the interior; the second, when the Renaissance school superseded the Gothic, and the pupils of Titian and Tintoret substituted, over one half of the church, their own compositions for the Greek mosaics with which it was originally decorated; [Footnote: Signed Bartolomeus Bozza, 1634, 1647, 1656, etc.] happily, though with no good will, having left enough to enable us to imagine and lament what they destroyed. Of this irreparable loss we shall have more to say hereafter; meantime, I wish only to fix in the reader's mind the succession of periods of alteration as firmly and simply as possible. SECTION VI. We have seen that the main body of the church may be broadly stated to be of the eleventh century, the Gothic additions of the fourteenth, and the restored mosaics of the seventeenth. There is no difficulty in distinguishing at a glance the Gothic portions from the Byzantine; but there is considerable difficulty in ascertaining how long, during the course of the twelfth and thirteenth centuries, additions were made to the Byzantine church, which cannot be easily distinguished from the work of the eleventh century, being purposely executed in the same manner. Two of the most important pieces of evidence on this point are, a mosaic in the south transept, and another over the northern door of the facade; the first representing the interior, the second the exterior, of the ancient church.
