But let us consider about judgment, as the sculptors wish, and see whether it is not more necessary to one who works in fresco than to one who chisels in marble. For here not only is there no place for patience or for time, which are most mortal enemies to the union of the plaster and the colours, but the eye does not see the true colours until the plaster is well dry, nor can the hand judge of anything but of the soft or the dry, in a manner that anyone who were to call it working in the dark, or with spectacles of colours different from the truth, would not in my belief be very far wrong. Nay, I do not doubt at all that such a name is more suitable for it than for intaglio, for which wax serves as spectacles both true and good. They say, too, that for this work it is necessary to have a resolute judgment, to foresee the end in the fresh plaster and how the work will turn out on the dry; besides that the work cannot be abandoned so long as the plaster is still fresh, and that it is necessary to do resolutely in one day what sculpture does in a month. And if a man has not this judgment and this excellence, there are seen, on the completion of his work or in time, patches, blotches, corrections, and colours superimposed or retouched on the dry, which is something of the vilest, because afterwards mould appears and reveals the insufficiency and the small knowledge of the craftsmen, even as the pieces added in sculpture lead to ugliness; not to mention that when it comes about that the figures in fresco are washed, as is often done after some time to restore them, what has been worked on the fresh plaster remains, and what has been retouched on the dry is carried away by the wet sponge.
