Portrait of a Man with the Medal of Cosimo
Sandro Botticelli, 1474
what to study here
It shows how hard edges, a clear light-dark-light value pattern, and a small bright accent can organize a half-length figure against a hazy landscape.
Look at how the edges are handled. The vision guide reports that the boundary between face and sky, and the shoulder line against sky, is almost hard, and that the dark green tunic against the pale sky is the sharpest edge in the picture. Set that against the softer, hazier distant landscape and you can see how edge sharpness alone separates figure from space. Next, read the value structure by squinting: face and hands form one light shape, hair and tunic form one dark shape, and the golden medal is a small bright accent low in the center that pulls the eye down before the background pulls it back. Light comes from the left, modeling the face and neck while the hair stays deep in shadow. Study the hair: fine directional strokes suggest locks without separating every strand. The medal gets the finest linear marks for relief, and the neck blends softly into shadow. Note the warm, yellowish flesh anchored in ochre-like tones, not pink. Treat the hands as carefully painted as the face.
key decision
The painter kept the figure's outline against the sky almost hard while letting the distant landscape recede in pale, hazy greens. This edge contrast separates the figure from the space behind.
recreation guide
This recreation guide focuses on the technical execution of Sandro Botticelli’s *Portrait of a Man with the Medal of Cosimo* (1474), adhering to the Early Renaissance tempera tradition. The artwork is executed in egg tempera on a wood panel, a medium characterized by its fast-drying nature and the use of egg yolk as a binder (Source 1, Source 2). The distinctive quality of this period’s work relies on the artist’s ability to select materials that express specific qualities of nature rather than merely deceiving the eye with illusionistic depth (Source 3). The process demands a high degree of draftsmanship, where accuracy is defined by the emotional significance and vividness of form rather than mere scientific replication (Source 7).

materials
| item | purpose | modern equivalent |
|---|---|---|
| Poplar, willow, or linden wood panel | Support structure; Italian tradition favored seasoned poplar, willow, or linden, often radial cut to exclude sapwood (Source 4). | Stretched canvas is not appropriate for this historical recreation; use a solid wood panel prepared as described. |
| Animal-skin glue and resin | To create the 'size' mixture for coating the wood and adhering linen (Source 4). | Hide glue or rabbit-skin glue. |
| Linen cloth | Applied over the size to reinforce the panel and prevent cracking (Source 4). | Unbleached linen. |
| Gesso (gypsum/chalk and glue) | To create a smooth, hard, ivory-like surface for painting; applied in multiple layers (Source 4). | Pre-mixed gesso or traditional gesso grosso/secco. |
| Egg yolk | The primary binder for the tempera paint, mixed with pigments (Source 1, Source 2). | Fresh egg yolk, separated from white and membrane. |
| Pigments (earth tones, lapis lazuli, vermilion, etc.) | Colorants mixed with egg yolk. Botticelli’s palette typically included vibrant blues and reds, though specific mixes for this portrait are not detailed in sources. | Acrylic or oil paints are NOT suitable for this technique; use dry pigments or pre-mixed egg tempera. |
| Charcoal | For laying out the design on the prepared panel (Source 4). | Vine charcoal or willow charcoal. |
preparation
surface prep
Construct or acquire a solid wood panel, preferably radial-cut poplar, willow, or linden, excluding sapwood (Source 4). Plane and sand the wood. Coat the wood with a mixture of animal-skin glue and resin, then adhere a layer of linen to this 'size' (Source 4). Once dry, apply layer upon layer of gesso, sanding down each layer before applying the next. This process may involve up to 15 layers to achieve a smooth, hard surface resembling ivory (Source 4).
underdrawing
Lay out the design on the gessoed panel using charcoal (Source 4). The drawing must be highly finished to acquire the habit of minute visual expression, ensuring that subtleties become instinctive so the mind is free to dwell on bigger qualities during painting (Source 7). The drawing should not merely be scientifically accurate but must present the form in a vivid manner that conveys emotional significance (Source 7).
underpainting
Egg tempera is typically applied directly over the white gesso ground. Unlike oil painting, which allows for extensive underpainting and glazing over days, tempera is fast-drying and applied in small, almost transparent brushstrokes (Source 4). There is no specific source indicating a distinct underpainting phase for this specific work, so the artist should proceed to the first pass of color application.
color palette
General Earth Tones
Ochres, umbers, and siennas mixed with egg yolk.
General use in this artist's palette for modeling forms and shadows.
Vibrant Reds/Blues
Vermilion or cinnabar for reds; Lapis lazuli or azurite for blues.
Botticelli is known for vibrant colors. While specific colors for the medal or clothing are not detailed in the sources, these were standard for Early Renaissance portraiture.
composition
The sources do not describe the specific compositional layout of *Portrait of a Man with the Medal of Cosimo*. Therefore, specific details about the subject's pose, the medal's placement, or background elements are omitted. Generally, Botticelli’s work emphasizes linear clarity and expressive form over naturalistic illusion (Source 3, Source 7).
step by step
underdrawing→first pass→refining→finishing
underdrawing
step 01
Transfer the design to the prepared gesso panel using charcoal.
Tip — Ensure the drawing is highly finished to capture minute visual expressions, as this habit is needed for the finer kind of drawing attempted later (Source 7).
Charcoal underdrawing
first pass
step 02
Mix pigments with egg yolk to create tempera paint. Apply paint using small brushes in very small, almost transparent brushstrokes.
Tip — Tempera is fast-drying; work in small areas. Do not attempt to blend wet-on-wet as with oils.
Egg tempera application
refining
step 03
Build up volumetric forms using thin layers of paint. Continue adding layers to achieve depth and detail.
Tip — Remember that the medium has limitations; do not attempt more than it is capable of doing. Focus on the vitality of the medium rather than deceptive illusion (Source 3).
Layering for volume
finishing
step 04
Complete the painting by ensuring the emotional significance of the form is conveyed. The accuracy of the drawing should be judged by how completely it conveys this significance, not by scientific realism (Source 7).
Tip — Avoid the 'meretricious attempt to deceive the eye' by focusing on the painted symbols and their emotional truth (Source 3).
Artistic accuracy
critical techniques
Egg Tempera Layering
Using small brushes dipped in pigment and egg-yolk mixture, paint is applied in very small, almost transparent brushstrokes. Thin layers create volumetric forms (Source 4).
Gesso Preparation
Applying up to 15 layers of gesso, sanding between each, to create a smooth, hard surface not unlike ivory (Source 4).
Expressive Draftsmanship
Drawing must be more than accurate; it must present form vividly and convey emotional significance, becoming instinctive through hard application (Source 7).
common pitfalls
- →Attempting to create an illusion of natural appearances that tricks the eye, which subordinates the enjoyment of the medium and results in a 'meretricious' effect rather than fine art (Source 3).
- →Ignoring the limitations of the tempera medium, which is fast-drying and requires small, transparent strokes, unlike the more tolerant oil paint (Source 1, Source 4).
- →Failing to finish the underdrawing with minute visual expression, which is necessary for the subtleties of the final painting to become instinctive (Source 7).

read from the painting
observed from the image, not the label6 dominant colors, measured
what the eye sees
Light rakes across the figure from the left, creating a strong modeling effect on the face and neck while leaving the hair in deeper shadow. The eye enters at the direct gaze and yellow-gold medal held prominently in the lower center, which anchors the composition and draws attention downward before the landscape background pulls it back. The figure occupies the upper two-thirds with a sharp tonal boundary between the dark green tunic and the pale sky, while the distant landscape recedes with softer greens and atmospheric haze.
value structure
The darkest darks are concentrated in the hair mass and the deep forest green of the clothing. Mid-tones dominate the face and neck with warm, yellowish undertones. The medal is a distinct light-middle value (golden ochre), and the background sky is the palest value overall, creating maximum separation from the hair. Squint and you see: face and hands as a light shape, hair and clothing as a dark shape, medal as a small bright focal point.

edges and brushwork
Edges are remarkably crisp and deliberate—the boundary between face and background air is almost hard, as is the shoulder line against sky. The hair is rendered with fine, directional strokes that suggest individual locks without overworking; note how the brown strokes follow the curve and weight of the hair mass. The medal receives the finest detail work with incised linear marks describing relief, while softer blending occurs in the neck transition into shadow.
a working sequence
- 01
Establish the value underpainting
Block in the composition with raw umber thinned to a wash. Lay down the dark hair mass as a single unified shape, the face and neck as a lighter, unified mass, and the medal as a small highlight shape. Keep the background landscape very light and soft. This is your road map—don't overdefine details yet.
- 02
Model the face with warm mid-tones
Mix your flesh tone: yellow ochre + raw umber + cadmium red + white, adjusted to match the warm, slightly golden skin. Use a #4 filbert to establish the front plane of the face—forehead, cheeks, nose, chin—with directional strokes following the contours. Leave the shadow side (left side of face) darker by mixing less white into your base tone. Notice the subtle modulation: the cheekbones catch more light than the temples.
- 03
Define the hair with layered darks
Darken your base with viridian + raw umber + cadmium red. Using a #2 round, map the individual lock patterns on the outer edges of the hair mass, especially the shoulders and the lower curls. Leave the inner hair slightly lighter to show form. The red cap sits on top—don't blend it into the hair; it should read as a separate object with a clean edge.
- 04
Paint the tunic and establish green depth
Mix the rich dark green: viridian + raw umber + a touch of cadmium red to desaturate it slightly. Block in the entire torso and shoulders, noticing it's darker than the hair in places. Use a filbert to follow the drape folds with directional strokes—the tunic has subtle vertical pleating visible in the shadows. The edge where green meets sky is your hardest edge in the painting; keep it crisp.
- 05
Paint and detail the medal
The medal is golden ochre with red undertones—mix yellow ochre + raw umber + touch of cadmium red for the base. Once dry, use a #2 round with thinned dark pigment (viridian + umber) to inscribe the linear relief details in the medal's face. The medal casts a small shadow on the fingers below it; this shadow should be warmer than the medal itself, using ochre + umber darkened. The hands holding it are flesh-tone with subtle darker modeling in the knuckles.
- 06
Build the atmospheric landscape background
Mix a very pale green-gray: titanium white + viridian + touch of raw umber. Using a larger filbert, lay in the distant fields with horizontal strokes—notice they're lighter and grayer than any local color. Add the cypress or dark foliage on the far right with a darker viridian-umber mix (still lighter than the foreground). The sky above is nearly white with a faint cool tint; use titanium white + whisper of viridian. Keep all background edges soft and atmospheric, especially along the horizon line.
- 07
Refine facial anatomy and expression
The eyes are crucial to likeness: they gaze directly outward with a clear, penetrating expression. Mix a warm mid-brown (raw umber + touch of cadmium red) for the iris, and use white mixed with the flesh tone for the highlight. The nose is long and slightly convex; strengthen the shadow line running down the left side with a dark warm brown. The mouth is small and neutral—a thin line of darker flesh tone defines the lip edge. Sharpen the jaw line by darkening the shadow beneath it.
- 08
Unify and final details
Step back and check proportions: the head should occupy roughly the upper third of your composition. The medal should be clearly the second focal point. Soften any overly harsh edges in the neck and shoulder transitions with a very light touch of blending. Add final touches to the red cap—it may have slight modeling folds; use a darker red (cadmium red + touch of raw umber) for shadows. Ensure the hard edge between hair and sky remains crisp and undisturbed.
where studies of this painting go wrong
- Overworking the hair—it should read as a unified dark mass with directional indication of locks, not every individual strand. Stop before it looks photographic.
- Making the face too pale or too pink. This face is warm and golden; keep your flesh tone anchored to ochre and umber, not just red and white.
- Softening the edge between the dark tunic and pale sky. This hard edge is essential to the figure's graphic presence; preserve it.
- Treating the background landscape as equally detailed as the foreground. It must remain soft, hazy, and atmospheric—use horizontal strokes and pale, muted greens to push it back.
- Neglecting the medal's subtle shadow and the articulation of the hands holding it. The hands are as carefully painted as the face; don't rush them.
