100 THE STONES OF VENICE
or vaults it might otherwise appear dangerously independent of the material within.
§ 32. LAW III. All shafts are to be solid. Wherever, by the smallness of the parts, we may be driven to abandon the incrusted structure at all, it must be abandoned altogether. The eye must never be left in the least doubt as to what is solid and what is coated. Whatever appears probably solid must be assuredly so, and therefore it becomes an inviolable law that no shaft shall ever be incrusted. Not only does the whole virtue of a shaft depend on its consolidation, but the labour of cutting and adjusting an incrusted coat to it would be greater than the saving of material is worth. Therefore the shaft, of whatever size, is always to be solid; and because the incrusted character of the rest of the building renders it more difficult for the shafts to clear themselves from suspicion, they must not, in this incrusted style, be in any place jointed. No shaft must ever be used but of one block; and this the more, because the permission given to the builder to have his walls and piers as ponderous as he likes, renders it quite unnecessary for him to use shafts of any fixed size. In our Norman and Gothic, where definite support is required at a definite point, it becomes lawful to build up a tower of small stones in the shape of a shaft. But the Byzantine is allowed to have as much support as he wants from the walls in every direction, and he has no right to ask for further licence in the structure of his shafts. Let him, by generosity in the substance of his pillars, repay us for the permission we have given him to be superficial in his walls. The builder in the chalk valleys of France and England may be blameless in kneading his clumsy pier out of broken flint and calcined lime; but the Venetian, who has access to the riches of Asia and the quarries of Egypt, must frame at least his shafts out of flawless stone.1
