With sinopia-the preliminary sketch found on a layer of its own on the wall underneath the fresco, or painting on freshly spread, moist plaster-one reaches the point at which a work that merely served as technical preparation becomes a formal drawing expressing an artistic intention. Long before the appearance of actual small-scale drawing, this procedure was much used for monumental murals. Such preliminary sketches may merely indicate the main contours or may predetermine the final execution down to exact details. As shown by an increasing number of findings and investigations, drawings form the material basis of mural, panel, and book paintings. Essentially, every painting is built up of lines and pre-sketched in its main contours only as the work proceeds is it consolidated into coloured surfaces. Similarly, points and lines marked on a raw stone block represent auxiliary drawings for the sculpture that will be hewn out of the material.

Often the drawing is absorbed by the completed work or destroyed in the course of completion.
