§ 85 Drawing, by Transfer or Directly
After spreading the said composition or pigment all over the panel, the cartoon that you have made with figures and inventions all your own may be put on it, and under this cartoon another sheet of paper covered with black on one side, that is, on that part that lies on the priming. Having fixed both the one and the other with little nails, take an iron point or else one of ivory or hard wood and go over the outlines of the cartoons, marking them firmly. In so doing the cartoon is not spoiled and all the figures and other details on the cartoon become very well outlined on the panel or framed canvas.
He who does not wish to make cartoons should draw with tailors’ white chalk over the priming or else with charcoal made from the willow tree, because both are easily erased. Thus it is seen that the artist, after the priming is dry, either tracing the cartoon or drawing with white chalk, makes the first sketch215 which some call ‘imporre’ (getting it in). And having finished covering the whole the artist returns to it again to complete it with the greatest care: and here he employs all his art and diligence to bring it to perfection. In this manner do the masters in oil proceed with their pictures.
