60 THE STONES OF VENICE

balustrade. This balustrade is worked on the outside with mouldings, of which I shall only say at present that they are of exactly the same school as the greater part of the work of the existing church. But the great horizontal pieces of stone which form the top of this balustrade are fragments of an older building turned inside out. They are covered with sculptures on the back, only to be seen by mounting into the gallery. They have once had an arcade of low wide arches traced on their surface, the spandrils filled with leafage, and archivolts enriched with studied chainwork and with crosses in their centres. These pieces have been used as waste marble by the architect of the existing apse. The small arches of the present balustrade are cut mercilessly through the old work, and the profile of the balustrade is cut out of what was once the back of the stone; only some respect is shown for the crosses in the old design, the blocks are cut so that these shall be not only left uninjured, but come in the centre of the balustrades.

§ 32. Now let the reader observe carefully that this balustrade of Murano is a fence of other things than the low gallery round the deserted apse. It is a barrier between two great schools of early architecture. On one side it was cut by Romanesque workmen of the early Christian ages, and furnishes us with a distinct type of a kind of ornament which, as we meet with other examples of it, we shall be able to describe in generic terms, and to throw back behind this balustrade, out of our way. The front of the balustrade presents us with a totally different condition of design, less rich, more graceful, and here shown in its simplest possible form. From the outside of this bar of marble we shall commence our progress in the study of existing Venetian architecture. The only question is, do we begin from the tenth or from the twelfth century?

§ 33. I was in great hopes once of being able to determine this positively; but the alterations in all the early buildings of Venice are so numerous, and the foreign fragments introduced so innumerable, that I was obliged to leave the
