recreation guide

This recreation guide addresses the painting of Giovanni Battista Piranesi’s 'Pyramid of Caius Cestius' in oil, a medium distinct from his primary fame as an etcher. While Piranesi is historically renowned for his prints depicting Roman ruins and his influence on Neoclassicism (Source 4), this guide adapts general oil painting practices of the period to his architectural subject matter. The artwork belongs to the cityscape genre, which often functions as a topographical view where buildings are prominently featured (Source 6). Piranesi’s approach to the past was dynamic, believing Romans improved upon Greek models, and he utilized a method summarized by his phrase 'col sporcar si trova' ('by messing about, one discovers') (Source 4). Consequently, the painting process should embrace a degree of experimental discovery rather than rigid pre-planning, consistent with his free relationship to historical sources.

preparation

surface prep

Prepare a neutral ground. While specific preparation for this exact oil work is not detailed in the sources, the technique described involves a 'grisaille' (monochrome underpainting) that must be 'quite dry' before proceeding (Source 1). Ensure the surface is sealed to prevent oil absorption issues during the glazing phase.

underdrawing

Use contour drawing principles to establish the mass and volume of the Pyramid and surrounding architecture. Focus on the outlined shape and three-dimensional perspective rather than minor details initially, as contour drawing emphasizes form, weight, and space (Source 7). Given Piranesi’s 'sketch-like look' in his early etchings (Source 4), the underdrawing should remain fluid and expressive.

underpainting

Execute a grisaille (monochrome underpainting) using black, ultramarine, and white mixed with oil of copavia (Source 1). This step mentally extracts red and yellow colors, translating what would be left in nature if those colors were absent (Source 1). This establishes the chiaroscuro and structural integrity of the cityscape before color is introduced.

color palette

Grey/Blue-Grey

Black, Ultramarine, White

Underpainting and shadows; establishes the 'grey bloom' and coldness in darker areas (Source 1).

Warm Earth Tones

Yellow and Red ochres/siennas

Glazing and scumbling to simulate the stone of the Pyramid and atmospheric light, mimicking the 'yellow and red tones as they occur' (Source 1).

Complementary Contrasts

Varied based on adjacent tones

Harmonizing colors inherent to the objects; using simultaneous contrast to enhance the perception of light and shadow on the architectural forms (Source 2, Source 5).

composition

The composition should treat the Pyramid as a prominent building in a topographical view (Source 6). Utilize the principles of composition where line guides the eye and value emphasizes form (Source 8). Piranesi’s works often feature a 'wider perspective on the past' and a dynamic growth of society, suggesting the composition should feel expansive and monumental (Source 4). Apply the law of simultaneous contrast to ensure that the lightest tones are lowered and darkest tones heightened where colors juxtapose, creating a true gradation of light (Source 2, Source 5).

step by step

underdrawing→underpainting→first pass→refining→finishing→varnishing

underdrawing

step 01
Sketch the Pyramid and surrounding cityscape using contour lines to define mass and volume. Focus on the silhouette and spatial relationships rather than fine detail.
Tip — Ensure lines convey thickness and depth, not just outlines (Source 7).
Contour Drawing

underpainting

step 02
Apply a grisaille using black, ultramarine, and white with oil of copavia. Establish the full range of values from dark shadows to bright highlights.
Tip — Mentally extract red and yellow colors; paint only what remains if those colors were absent (Source 1).
Grisaille

first pass

step 03
Allow the grisaille to dry completely. Begin glazing with transparent coats of yellow and red tones using oil.
Tip — Apply color much as one would tint an engraving with watercolors (Source 1).
Glazing

refining

step 04
Use scumbling (semi-opaque painting) over darker grounds to create coldness or a 'grey bloom' where needed, particularly in shadows or distant architectural elements.
Tip — Observe how the underlying painting makes itself felt through the semi-opaque layer (Source 1).
Scumbling

finishing

step 05
Adjust colors based on simultaneous contrast. If a warm tone is next to a cool tone, adjust the perception of each to harmonize the composition.
Tip — Be aware that the eye may see the complementary of a previously viewed color; correct for this visual fatigue (Source 2).
Simultaneous Contrast

varnishing

step 06
Once mastery is gained, mix varnish and oil for final glazes to deepen tones and unify the surface.
Tip — This method was practiced by old masters and helps achieve depth (Source 1).
Varnish Glazing

critical techniques

Glazing and Scumbling

Used to build color over a dry monochrome underpainting. Glazing provides transparent color, while scumbling provides semi-opaque texture and coldness in shadows. This was a common practice among old masters (Source 1).

Simultaneous Contrast

Applied to harmonize colors inherent to the objects. The painter must perceive how contiguous colors modify each other, ensuring that lightest tones are lowered and darkest heightened at juxtapositions (Source 2, Source 5).

Contour Drawing

Used in the underdrawing phase to emphasize mass, volume, and three-dimensional perspective rather than minor details (Source 7).

common pitfalls

→Applying color before the grisaille is completely dry, which can muddy the underpainting (Source 1).
→Ignoring simultaneous contrast, leading to inaccurate color perception where adjacent tones modify each other (Source 2).
→Over-modeling or becoming too tied to the outline, which contradicts the advice to check tendencies toward 'smallness' or rigidity (Source 3).
→Failing to 'mess about' or experiment, contrary to Piranesi’s philosophy of discovery through practice (Source 4).

what the sources don't tell us

Where the corpus is silent, we say so rather than guess. These are the gaps a complete recreation guide would normally cover that our source passages don't.

·Specific pigment recipes used by Piranesi for oil painting are not available, as he is primarily known for etching.
·The exact dimensions and aspect ratio of this specific oil painting are not provided in the sources.
·Detailed visual description of the specific background elements (e.g., specific buildings, figures) in this oil version is not present in the sources; the guide relies on general cityscape and Piranesi’s general style.
