Raphael, 1512
what to study here
It shows how a dense crowd stays readable through three value zones, a single directed light, and deliberate shifts between crisp and soft edges.
This detail is worth studying for how value and warmth organize a crowded scene. The vision analysis reads the light as coming from the upper left, raking across the figures and lighting the upper portions of fabrics and forms. Squinting, the image resolves into three zones: a dark shadowed background at upper right, warm mid-tone walls and bodies, and bright white fabrics that act as the lightest anchors and pull the eye forward. The eye enters at the white drapery, then moves left to the red-robed elder, so the path through the picture is set by value and warmth together. Edges are varied on purpose. Folds in the white cloth are crisp, while flesh and distant figures soften into blended transitions. The foreground crowd, from children to soldiers to observers, is layered so the bodies press into depth. Copy the value zones and edge control first, then the figures. The medium is fresco, so passages are worked in sections on wet plaster, and the general fresco context in the input notes scraped indentations in wet plaster for eyes and folds. Whether they appear in this detail is not stated.
key decision
Raphael grouped the scene into three value zones, with dark background, warm mid-tones, and bright white fabrics as key anchors, all under one consistent light from the upper left. Edges are crisp on the white folds and soft on flesh and distant figures, which separates the planes.
recreation guide
The Expulsion of Heliodorus from the Temple (1512) is a High Renaissance history painting executed in buon fresco. As a history painting, it depicts a narrative moment from the Bible, characterized by a large number of figures and dynamic action (Source 6). Raphael was renowned for his extensive preparatory drawings, often creating multiple variants to refine poses and compositions before scaling them up for the final work (Source 7). The artwork exemplifies the 'grand manner' of the High Renaissance, absorbing influences from contemporaries like Michelangelo while maintaining Raphael’s cohesive style (Source 8).
estimated time
Several weeks to months, depending on wall size, due to the strict daily time limits of fresco painting (7-9 hours of working time per day) (Source 1).

materials
| item | purpose | modern equivalent |
|---|---|---|
| Lime plaster (arriccio and intonaco) | The structural base and painting surface. Arriccio is the rough underlayer; intonaco is the thin, smooth top layer applied daily. | Hydraulic lime plaster or traditional slaked lime plaster. |
| Alkaline-resistant pigments | Colors must withstand the high pH of wet lime. Ground in water, they become part of the wall via carbonatation. | Natural earth pigments (ochres, umbers), mineral pigments (ultramarine, azurite), and lime-stable synthetic pigments. |
| Water | Vehicle for the pigment. No binder is required as the lime acts as the binder. | Distilled or clean tap water. |
| Soot (spolvero) | Used to transfer pricked cartoon drawings onto the plaster via pouncing. | Charcoal powder or commercial pounce powder. |
| Sinopia pigment (red earth) | Used for sketching compositions directly on the arriccio underlayer. | Red ochre or raw sienna. |
| Blind stylus | A tool for scratching lines into wet plaster to create indentations without leaving visible marks, aiding in depth illusion. | A smooth, hard-pointed tool (e.g., bone folder or polished wood). |
preparation
surface prep
The wall must first be prepared with a rough, thick undercoat of plaster known as arriccio (Source 3). This layer is allowed to dry for several days. If painting over an existing fresco, the surface must be roughened for adhesion (Source 1).
underdrawing
Raphael likely sketched the composition on the arriccio using sinopia (red pigment) or charcoal (Source 1, Source 3). He also extensively used a 'blind stylus' to scratch lines into the plaster, leaving only indentations to guide the painting and enhance the illusion of depth (Source 7). Additionally, full-size cartoons were likely pricked and pounced with soot (spolvero) to transfer main lines onto the wet intonaco (Source 1, Source 7).
underpainting
In buon fresco, there is no traditional underpainting layer. The pigment is applied directly to the wet intonaco. However, Raphael may have used lime as a binding medium for some pigments to slow drying and extend working time (Source 3).
color palette
Reds and Earth Tones
Red ochre, vermilion (if lime-stable), raw sienna
General use in Raphael's palette for drapery and skin tones. Specifics for this painting are not detailed in sources.
Blues
Ultramarine or azurite
General use in High Renaissance frescoes for skies and drapery. Specifics for this painting are not detailed in sources.
Whites and Highlights
White lead (used a secco) or lime wash
Highlights and adjustments. Note: Pure white is difficult in buon fresco; often added a secco.
composition
As a history painting, the composition likely features a large number of figures depicting a narrative moment (Source 6). Raphael characteristically refined poses through extensive preparatory drawings, borrowing figures from stock drawings to achieve grace and variety (Source 7). The composition would have been scaled up from cartoons and transferred via pouncing (Source 7).
step by step
underdrawing
step 01
Apply the arriccio (rough underlayer) to the wall and allow it to dry for several days.
Tip — Ensure the surface is stable before proceeding.
Arriccio application
step 02
Sketch the composition on the arriccio using sinopia (red pigment) or charcoal. Alternatively, prick full-size cartoons and pounce them with soot to transfer lines.
Tip — Raphael also used a blind stylus to scratch guiding lines into the plaster.
Sinopia / Spolvero
first pass
step 03
Apply a thin, smooth layer of fresh lime plaster (intonaco) to the section to be painted that day (the giornata).
Tip — Only apply as much plaster as can be painted in 7-9 hours.
Giornata
step 04
Begin painting within one hour of applying the intonaco. Use alkaline-resistant pigments ground in water.
Tip — Work quickly; the plaster dries in 10-12 hours.
Buon Fresco
refining
step 05
Scrape indentations into wet plaster in specific areas (e.g., eyes, folds) to increase the illusion of depth and accentuate forms.
Tip — This technique was used by Raphael and Michelangelo to make eyes seem deeper and more pensive.
Scraping indentations
finishing
step 06
Allow the plaster to dry and undergo carbonatation, fixing the pigment in a protective lime crust.
Tip — Do not paint over dried intonaco with buon fresco; remove unpainted plaster if mistakes are made.
Carbonatation
step 07
If necessary, apply corrections or details using fresco-secco (pigments mixed with organic binders or lime water on dry plaster).
Tip — This allows for retouching but is less durable than buon fresco.
Fresco-secco
critical techniques
Buon Fresco
Painting with water-ground pigments on wet lime plaster. The pigment becomes an integral part of the wall through carbonatation.
Giornata
Dividing the painting into daily sections based on the amount of plaster that can be applied and painted before it dries.
Blind Stylus
Scratching lines into wet plaster to create invisible guides and enhance depth illusion, a technique Raphael used extensively.
Spolvero (Pouncing)
Transferring pricked cartoon drawings to the wall using soot powder to create dotted guidelines.

what the eye sees
Light rakes across this densely populated interior from the upper left, creating strong drama around the central standing figure in dark robes and the elderly bearded cardinal in rich burgundy. The eye enters at the bright white fabrics framing the central figures, then reads left to the red-robed elder, creating a narrative arc through value and chromatic warmth. The architectural backdrop (visible columns and walls) recedes into shadow at upper right, while the foreground crowd of witnesses—ranging from children to soldiers to noble observers—creates a layered, three-dimensional press of bodies. The composition is unified by the diagonal thrust of light from upper left, consistently illuminating the upper portions of figures and fabrics.
value structure
The darkest darks sit in the background shadow (upper right) and in the deep folds of the dark robes worn by the central figures. Mid-tones dominate the architectural planes and flesh tones. The lightest lights are concentrated in the white fabrics—particularly the drapes of the central figures—which act as key value anchors. When you squint, the composition resolves into three clear zones: dark shadowed background, warm mid-tone walls and crowd bodies, and bright white accent fabrics that pull the eye forward.

edges and brushwork
Edges vary deliberately: the white fabrics show crisp fold lines where light catches crisp cloth geometry, while flesh tones and distant figures fade into soft, blended transitions. The brushwork follows the direction of forms—visible directional strokes up and down drapery folds, circular strokes for heads and modeling facial planes. Glazed shadows are applied thinly and blend into forms below, while opaque light areas are built up with thicker, more visible paint, particularly in the white fabrics and highlighted flesh.
a working sequence
Underpainting and spatial structure
Using burnt umber diluted with linseed oil, block in the basic composition. Establish the deep shadow of the upper-right background and the warm wall plane. Place all figures at basic proportions: the tall central figure with dark robes, the red-robed elder rising above and to the left, the crowd arranged in depth. Don't model yet—think of this as mapping out where light and shadow zones will live.
Value architecture
Block in the three major value zones in roughly correct proportion: dark background (upper right and recesses), warm mid-tone walls and figure bodies, bright white accents on central figures. Use burnt sienna + white for the warm mid-tones, keep the background dark and cool. This step is about proportional clarity—can you squint and see the composition as readable light-dark shapes?
Anchor the red cardinal
Establish the burgundy robe of the elderly bearded figure at the left. Mix cadmium red + raw sienna + a touch of white to create a rich, sophisticated red (not bright orange, not purple). Block in the volume of the robe, noting how it drapes and folds. Keep the warm light hitting the upper surfaces and let cooler shadows fall in the folds. This is your chromatic anchor—everything else will relate to this color.
White drapery and fabric structure
The white fabrics framing the central figures are not pure white but subtle off-whites with warm and cool shifts. Mix titanium white + touch of raw sienna for the warm-lit sides, and titanium white + tiny touch of ultramarine (if available) or burnt umber for cool-shadowed folds. Model the three-dimensional volume of each piece of cloth. Pay attention to the cast shadows beneath folds—they should be warm (using burnt sienna) to suggest the warm light source above-left.
Flesh tones and facial modeling
Build the warm skin tones systematically. Start with a mid-tone base (raw sienna + white), then add warm highlights on the upper-left-facing cheeks and foreheads (adding more white and a touch of cadmium red for warmth), and shadows on undersides of chins and noses (using burnt umber + touch of ultramarine if available). The central figures' faces should be warmer and lighter than the background crowd. Don't overblend—visible brushwork showing the warm and cool shift reads more convincing than a muddy blend.
Facial features and expressions
With flesh structure in place, refine the faces. The elderly cardinal's white beard is a key detail—keep it luminous but model its volume. Direct the gaze of the central figures to clarify the narrative. Add the variety of ages and expressions in the crowd witnesses—some noble, some startled, some observing. Use small brushwork but maintain the overall value relationships; don't let detail work pull faces darker than they should read.
Atmospheric depth and final glazing
Soften and mute the background figures with a thin glaze (burnt umber + sienna + white, applied loosely). Their edges should blur slightly and their color should feel slightly cooler or more atmospheric than the foreground. Bring forward the foreground crowd by keeping their edges sharper and their colors slightly more saturated. This step creates the illusion of distance without moving anything—pure atmospheric perspective.
Edge refinement and final details
Walk through the composition and selectively sharpen and soften edges: crisp the fold lines of the white drapery, soften the transition between distant crowd heads and the background, sharpen the profile of the central figure. Check that the light direction is consistent—all shadows should respect the upper-left light source. Add any metallic or ornamental details visible (armor, jewelry, chains) with restrained color—these should read as accent, not dominate.
