Those who have written on the practice of painting have always recommended the use of few colours for flesh. Reynolds and others quote even ancient authorities as recorded by Pliny, and Boschini gives several descriptions of the method of the Venetians, and particularly of Titian, to the same effect. "They used," he says, "earths more than any other colour, and at the utmost only added a little vermilion, minium, and lake, abhorring as a pestilence biadetti, gialli santi, smaltini, verdi-azzurri, giallolini."183 Elsewhere he says,184 "Earths should be used rather than other colours:" after repeating the above prohibited list he adds, "I speak of the imitation of flesh, for in other things every colour is good;" again, "Our great Titian used to say that he who wishes to be a painter should be acquainted with three colours, white, black, and red."185 Assuming this account to be a little exaggerated, it is still to be observed that the monotony to which the use of few colours would seem to tend, is prevented by the nature of the Venetian process, which was sufficiently conformable to Goethe's doctrine; the gradations being multiplied, and the effect of the colours heightened by using them as semi-opaque mediums. Immediately after the passage last quoted we read, "He also gave this true precept, that to produce a lively colouring in flesh it is not possible to finish at once."186 As these particulars may not be known to all, we add some further abridged extracts explaining the order and methods of these different operations.
"The Venetian painters," says this writer,187 "after having drawn in their subject, got in the masses with very solid colour, without making use of nature or statues. Their great object in this stage of their work was to distinguish the advancing and retiring portions, that the figures might be relieved by means of chiaro-scuro—one of the most important departments of colour and form, and indeed of invention. Having decided on their scheme of effect, when this preparation was dry, they consulted nature and the antique; not servilely, but with the aid of a few lines on paper (quattro segni in carta) they corrected their figures without any other model. Then returning to their brushes, they began to paint smartly
