what to study here
It shows how line direction and density alone can carry form, light, and scale across a large architectural subject.
Read this one as a lesson in building tone with line alone. The vision guide describes parallel hatching that follows the curve of the cylindrical drum, with cross-hatching added only where shadow deepens. Edges are crisp and geometric. Nothing is blended, so all tonal change comes from how dense the lines are and which way they run. Look at how the value structure sorts into three zones: bright surfaces catching light from the upper left, mid-tones, and near-black pockets in the arch recesses and on the shaded face of the conical tower. Squint and the form reads as a silhouette against a luminous sky. Note the contrast in handling: the foliage at the margins is loose and scribbled, set against the rigid stone. The tiny figures on stairs and platforms fix the scale of the mausoleum, so check how small they are against the columns. The palette is a grayscale run from near-white to near-black. Copy the line direction first, then the value zones, and leave the tower's proportions until you have both.
key decision
The painter builds all tone through line density and direction, with hatching that follows each surface's curve and cross-hatching reserved for shadow, and never blends. This keeps the geometry crisp and the light/dark contrast strong.
recreation guide
This recreation guide addresses the painting of a Neoclassical cityscape titled 'Ancient mausoleum erected to the ashes of a Roman Emperor,' attributed to Giovanni Battista Piranesi (1750). While Piranesi is historically renowned for his etchings and architectural prints rather than oil paintings, this guide adapts his documented visual language—characterized by dramatic perspective, monumental ruins, and a 'sketch-like' immediacy—to the medium of oil. The artwork reflects the Neoclassical interest in the 'Golden Age' of Roman construction, contrasting with the romantic ruins of the late Baroque (Source 3). The composition likely employs the dynamic, self-conscious engagement with the past that Piranesi championed, potentially utilizing his mantra 'col sporcar si trova' ('by messing about, one discovers') to allow for organic discovery in the rendering of complex architectural forms (Source 3).

materials
| item | purpose | modern equivalent |
|---|---|---|
| Oil of copavia (or modern damar/resin varnish substitute) | Medium for the first and second paintings, as cited in Reynolds' method which aligns with the glazing techniques relevant to this period's oil practice. | Damar varnish or Galkyd |
| Ultramarine | Primary blue pigment for the grisaille underpainting and sky tones. | Ultramarine Blue (synthetic or natural) |
| Black (Ivory Black or Lamp Black) | For defining shadows and structural lines in the monochrome underpainting. | Ivory Black |
| White (Lead White or Titanium White) | For highlights and mixing tints in the grisaille stage. | Titanium White (for safety) or Flake White (for historical accuracy) |
| Red and Yellow earth tones (Ochre, Sienna, Vermilion) | For glazing and scumbling to introduce warmth and local color after the monochrome base. | Yellow Ochre, Burnt Sienna, Cadmium Red |
| Turpentine or Spike Oil | Vehicle to ensure a dull, matte surface if aiming for a mural-like finish, or to thin initial washes. | Odorless Mineral Spirits or Gamsol |
preparation
surface prep
Prepare a rigid support (canvas or panel) primed with a neutral ground. If aiming for the monumental scale associated with Piranesi's architectural works, consider a 'Marouflage' technique where the canvas is fixed to resist dampness and integrate with the wall, ensuring a mat or dull surface that does not shine at any angle (Source 8). Use pigments mixed with little oil or wax, using petroleum or turpentine as vehicles to ensure this dullness (Source 8).
underdrawing
Piranesi’s early works, such as the first state of the *Carceri* (1750), are described as having a 'sketch-like look' (Source 3). Begin with a loose, energetic underdrawing that captures the massive scale and perspective of the mausoleum without excessive refinement. This aligns with his philosophy of 'col sporcar si trova' (discovering through experimentation) (Source 3).
underpainting
Execute a grisaille (monochrome underpainting) using black, ultramarine, and white, mixed with oil of copavia (Source 1). This stage establishes the value structure and form. Mentally extract red and yellow colors, translating what would remain in nature if those hues were absent (Source 1). This creates a solid foundation for the subsequent glazing.

Cool Greys
Ultramarine, White, Black
Scumbling over darker grounds to create a 'grey bloom' and coldness in shadowed architectural recesses (Source 1).
composition
The composition should reflect the Neoclassical attitude towards the past, emphasizing the 'magnificence' of Roman architecture (Source 7). Use strong linear perspective to guide the eye, consistent with Piranesi’s focus on 'Perspectives' and architectural etchings (Source 2). The arrangement of ruins should feel monumental and perhaps slightly fantastical, echoing the 'romantic and fantastic depictions of ruins' found in late Baroque works that influenced Piranesi (Source 3). Ensure the design harmonizes with the architectural character, appearing sufficiently flat or unrelieved to avoid detaching from the background if treated as a decorative piece (Source 8).
step by step
underdrawing
step 01
Sketch the mausoleum and surrounding ruins with loose, confident lines, emphasizing perspective and scale.
Tip — Allow for 'messing about' to discover forms, per Piranesi's mantra (Source 3).
Sketch-like immediacy
underpainting
step 02
Apply a grisaille using black, ultramarine, and white mixed with oil of copavia. Establish the full range of values from deep shadows to bright highlights.
Tip — Mentally exclude red and yellow tones to focus on form and light (Source 1).
Grisaille
first pass
step 03
Once the grisaille is dry, begin glazing with transparent coats of red and yellow oil colors. Apply these much like tinting an engraving with watercolors.
Tip — Use oil of copavia as the medium for these initial glazes (Source 1).
Glazing
refining
step 04
Use scumbling (semi-opaque painting) over darker areas to introduce cool grey blooms and coldness, allowing the underlying grisaille to show through.
Tip — This technique helps create atmospheric depth and texture in the stone surfaces (Source 1).
Scumbling
finishing
step 05
Refine the contrast between light and dark tones. Ensure that the juxtaposition of colors creates a true gradation of light, heightening the darkest tones and enfeebling the lightest where they meet (Source 6).
Tip — Be aware of simultaneous contrast; adjacent colors will affect each other's perceived tone (Source 5).
Chiaroscuro/Contrast
varnishing
step 06
If a matte finish is desired for a mural-like effect, use varnish mixed with oil sparingly, or rely on the initial turpentine-based vehicle to maintain dullness (Source 8).
Tip — Avoid a shiny surface that might distract from the architectural forms (Source 8).
Matte Finish
critical techniques
Glazing and Scumbling
Used to build color and atmosphere over a monochrome base. Glazing adds transparent color, while scumbling adds semi-opaque texture and coolness (Source 1).
Grisaille Underpainting
Establishes form and value using only black, ultramarine, and white, allowing for a clear separation of structure and color (Source 1).
Simultaneous Contrast
Awareness that adjacent colors influence each other's appearance, requiring careful adjustment of tones to maintain harmony and accuracy (Source 5).

what the eye sees
Light streams from the upper left, casting deep shadows on the right side of the cylindrical drum and beneath architectural elements. The eye lands first on the tall conical tower rising from the central platform—it's the compositional anchor—then expands to the surrounding colonnade and radiating steps. The foreground left features recessed arches and columns framing the view inward, while tiny scattered figures on stairs and platforms establish the mausoleum's monumental scale. Foliage and vegetation creep from the right margin and frame the left, providing organic contrast to the rigid geometry.
value structure
The range spans from near-white sky and illuminated dome surfaces to near-black shadows in arch recesses and the conical tower's shaded face. There are three distinct value zones: bright architectural surfaces catching the upper-left light, mid-tone secondary surfaces, and deep shadow pockets showing form dimensionality. Squint and the structure reads as silhouette against luminous sky—the contrast between brightly lit drum sections and dark recesses carries all the spatial information.

edges and brushwork
The line work is precise and deliberate. Architectural edges are crisp, following geometric rules—parallel hatching on cylindrical surfaces follows the curve, cross-hatching intensifies in shadow to build tone without blending. Foliage on the margins breaks this rigor with loose, energetic scribbled lines that feel organic against rigid stone. Sky and distant areas use minimal line, letting paper read as light, while shadow recesses grow dense and dark through accumulated parallel lines and bold cross-hatching. All tonal transition happens through line density and direction, never through soft blending.
a working sequence
Establish the linear framework
Lightly block in three guide lines: the bottom platform edge running left-right, the central vertical axis of the conical tower, and the curved receding edge of the cylindrical drum as it moves into space. These determine everything else. Double-check that the tower rises perpendicular to the platform and the drum's curve reads convincingly from this view angle.
Block major architectural masses
Define the silhouettes in light lines: the foreground colonnade with its recessed arches on the left, the central cylindrical drum with columns radiating around it, the elevated dome structure behind, and the platform-and-stairs system connecting them. Place the small figures loosely—they anchor scale and spacing. Do not add detail yet; you're mapping spatial relationships.
Develop the cylindrical drum and colonnade
This is the compositional anchor. Draw each column and capital, ensuring they wrap convincingly around the curve and narrow with perspective as they recede. Add the decorative bands, niches, and rectangular panel divisions visible on the drum surface. Use the figures on the upper terrace to verify scale; if they look too large or too small, the column spacing is off.
Render the conical tower precisely
The tall cone is the focal point—proportional precision here determines whether it reads elegant or clumsy. Draw its clean edges showing the subtle taper, and indicate how light strikes one face more than the other with a faint shadow edge. The basin it rises from has distinct faceted planes; sketch these carefully. Ornamental elements at the base should have enough detail to feel substantial without fussy overworking.
Develop foreground arches and recessed details
The left foreground is spatially complex: arches curve overhead, columns recede, blocks nest inside blocks. Draw these with care—the arch curves, fluting on columns, stone jointing. This recessed space will become your darkest shadow area, so establish its geometry now before hatching. Include the sculptural urns and relief panels visible in the shadowed bays; they need enough presence to feel weighty.
Build the value structure with parallel hatching
Begin establishing light and shadow. Use light, parallel hatching on surfaces facing the upper-left light source: the outer drum face, the bright dome, sunlit column sides. Keep the hatching lines close to the light source direction—nearly horizontal on horizontal surfaces, following the curve on cylindrical forms. In shadow areas, increase hatching density. Do not cross-hatch yet; build layers gradually so you stay in control of the value rise.
Deepen shadows with cross-hatching and detail
Now layer cross-hatching into your shadow areas to push them darker. Inside the foreground arches, beneath the drum's base, in recessed panels—these become your near-blacks. Add the ivy and foliage creeping in from the margins using loose, organic scribbled lines to contrast with rigid stone. Render the tiny figures on stairs and platforms with just enough definition to read as human forms against the architecture. Check perspective lines are converging correctly.
Final refinement and luminosity
Step back and assess the full value range. Strengthen the darkest darks in arch recesses and shadow faces if needed—push contrast to make the illuminated surfaces glow. Add fine detail to decorative moldings and carved elements in lit areas. The distant background dome should remain lighter and looser than the foreground, maintaining atmospheric depth. Ensure tiny figures read clearly. The entire image should feel architecturally convincing and spatially deep.
