View of the Tomb of Caius Cestius

surface prep

Prepare a neutral ground, likely a warm grey or ochre tone, to facilitate the glazing and scumbling techniques described in Source 1. Piranesi’s background as a draughtsman and engraver (Source 4) suggests a high value for precise linear definition, so the surface should be smooth enough to allow for fine detail in the architectural elements. The preparation should allow for the 'mental extraction' of red and yellow colors to create a monochrome base (Source 1).

underdrawing

Given Piranesi’s training as a draughtsman for Marco Foscarini and his study under Giuseppe Vasi, who noted his talent exceeded that of a mere engraver (Source 4), the underdrawing should be precise and architectural. Use charcoal to establish the strong linear perspective and structural integrity of the Tomb of Caius Cestius. Piranesi’s work often features 'romantic and fantastic depictions of ruins' (Source 3), so the drawing should emphasize the monumental scale and dramatic lighting inherent in his *Vedute*.

underpainting

Create a grisaille (monochrome underpainting) using black, ultramarine, and white, as suggested by Sir Joshua Reynolds’ method cited in Source 1. This step involves 'mentally extracting the red and yellow colours' to establish the tonal values and light/shadow structure without color interference (Source 1). This aligns with the 'old masters' practice of building up layers, which Piranesi’s Neoclassical contemporaries would have respected.

Glazing

Applying transparent coats of color over a dry monochrome underpainting to build up luminosity and depth, as practiced by old masters and described in Source 1.

Scumbling

Using semi-opaque paint to modify tones and create texture, particularly useful for atmospheric effects in the sky or distant ruins (Source 1).

Chiaroscuro

Using strong contrasts between light and dark to create volume and dramatic effect, consistent with Piranesi’s dramatic style and the principles of tonal gradation (Source 6).
