Leonardo da Vinci, 1503
what to study here
It shows how to model a face with one chalk, paper tone and a stump, keeping a tight value range against active hair.
This is a lesson in how far a single drawing medium can go. The whole head is in red chalk on warm paper, with no cool shadows. Paper tone serves as the highest light, so the lights are left alone rather than added. The face sits in a very narrow mid-tone band. Modeling comes from layering: the lightest touch for the cheekbone and temple, more for the eye sockets and beard shadow, and heavy pressure only for the darkest accents (pupil depth, nostril interior, deepest beard shadow). Edges are soft and blended, apparently with a stump, so the face is described by value rather than line. Compare that with the hair, which is built from rhythmic, curving strokes that follow the form of each lock. Study how the same chalk produces two textures, smooth blended skin and visible directional hair. Also note the downward gaze, carried by socket shadow rather than a dark, focused eye. Count your value steps before you start; there are only a handful.
key decision
Leonardo used paper tone as the lightest value and built everything else from layered red chalk, saving heavy pressure for a few small accents. Skin is blended soft while the hair keeps visible directional strokes.
recreation guide
This recreation guide addresses Leonardo da Vinci’s 'Head of a Man' (1503), a chalk drawing on paper. Unlike his oil paintings, which are renowned for their smooth, indistinguishable brushstrokes and sfumato technique (Source 6), this work utilizes dry media. The distinctive quality of such drawings lies in the application of color in a powdered state, where the pigment adheres to the support through mechanical means rather than a liquid binder (Source 3). Leonardo’s general practice emphasizes a profound understanding of anatomical construction beneath the surface appearance, requiring the artist to view the form not just as light and shade, but as a complex structure of bone and muscle (Source 5).

materials
| item | purpose | modern equivalent |
|---|---|---|
| Red and Black Chalk (Sanguine and Conté) | Primary drawing and shading media. Chalks are ground with water and clay or gum, remaining in a powdered state on the paper. | Soft red and black Conté crayons or high-quality sanguine chalks. |
| Toothed Paper | The support must have a rough natural surface or be prepared with pumice stone to mechanically hold the powdered chalk. | Heavyweight textured drawing paper (e.g., Ingres or Strathmore 400 series). |
| Kneaded Eraser and Bread Crumb | For lifting charcoal/chalk to correct errors. Bread is historically noted for offering 'no resistance' to correction. | Kneaded eraser; soft white vinyl eraser. |
| Blending Stump or Dry Brush | To model the forms and soften transitions, mimicking the 'sfumato' effect in dry media. | Paper stump or soft tortillon. |
preparation
surface prep
The paper support must possess a 'rough natural surface' or be treated with a layer of pumice stone to ensure the powdered chalk adheres mechanically (Source 3). Smooth paper will not hold the dry pigment effectively. Ensure the paper is clean and free of dust before beginning.
underdrawing
Begin with a light structural sketch. Leonardo’s practice requires a 'keen sense of construction' and knowledge of the 'bony structure of the skeleton' and muscle attachment (Source 5). Do not rely solely on surface observation; map the underlying anatomy first. Use a hard, light chalk or pencil to establish proportions. As advised for drawing from life, make the study slightly smaller than life to facilitate comparison (Source 2).
underpainting
Not applicable for this dry medium. However, the principle of correcting errors early applies: 'Make all corrections while you can in the charcoal stage' (Source 2). Do not proceed to heavy shading until the construction is accurate.
color palette
Red/Sanguine
Red chalk (likely red ochre or iron oxide based, consistent with ancient palettes mentioned in Source 7)
Modeling the flesh tones and warm shadows. Chalks are used in a powdered state with little to no medium (Source 3).
Black
Black chalk or charcoal
Deep shadows, defining contours, and adding contrast. Ancient artists used black prepared from combustion (Source 7).
White (Paper Tone)
The white of the paper itself
Highlights. In chalk drawing, the white is often reserved rather than applied, though white chalk can be used for specific highlights if the paper is toned.
composition
While specific compositional details of this particular head are not described in the sources, Leonardo’s general approach involves viewing nature as 'color, tone, texture and light and shade' backed by structural insight (Source 5). The portrait likely focuses on the head with minimal distraction, consistent with the 'unadorned' focus seen in his other works where 'eyes and hands have no competition from other details' (Source 6).
step by step
underdrawing
step 01
Lightly sketch the basic proportions of the head. Hold your drawing tool against the model (or reference) to ascertain length and scale (Source 2). Ensure the drawing is slightly smaller than life.
Tip — Check the alignment of features against the underlying skeletal structure (Source 5).
Proportional Measurement
step 02
Refine the outline and major anatomical landmarks. Correct any errors in construction now, as charcoal/chalk offers little resistance to erasure (Source 2).
Tip — Do not put down heavy pigment if there are 'obvious errors in construction or drawing' (Source 2).
Structural Correction
first pass
step 03
Apply red chalk to establish the mid-tones and general mass of the face. Use the side of the chalk for broad areas and the tip for details. The chalk is applied in a powdered state (Source 3).
Tip — Keep the pressure light to allow for blending later.
Dry Media Application
refining
step 04
Use a dry brush or blending stump to model the forms. Soften the transitions between light and shadow to achieve a smooth, blended effect reminiscent of Leonardo’s sfumato (Source 6).
Tip — Avoid harsh lines; Leonardo’s technique is characterized by being 'extremely smooth' with indistinguishable strokes (Source 6).
Blending/Sfumato
step 05
Add black chalk for deeper shadows and definition. Use contrast to strengthen the form. Be mindful of how black designs appear on different grounds, though here the ground is white paper (Source 4).
Tip — Use black sparingly to avoid muddying the red tones.
Contrast Application
finishing
step 06
Review the drawing from a distance. Place the drawing alongside the reference (if available) to compare scale and proportion (Source 2). Make final adjustments to the 'fleeting action' and expression (Source 5).
Tip — Ensure the 'hidden construction' is supported by the surface effects of light and shade (Source 5).
Final Assessment
critical techniques
Sfumato
While typically associated with oil, the principle of soft, smoky transitions applies to chalk. Blend thoroughly to avoid harsh lines, aiming for the 'shadowy quality' Leonardo is known for (Source 6).
Anatomical Construction
Understand the 'bony structure' and 'muscle attachment' beneath the skin. This knowledge allows for accurate rendering of the 'external and apparent' forms (Source 5).
Dry Media Handling
Chalks are applied as powder with minimal medium. The support must be rough enough to hold them mechanically (Source 3).

what the eye sees
Light streams from the upper left, modeling the frontal planes of the face while the right side recedes into shadow. The massive curled hair dominates the upper portion with densely packed loops, while the face anchors below—a severe, bearded profile tilted slightly leftward. The eye lands first on the downward-gazing eyes and prominent nose ridge, which catch the strongest light. The composition reads as a study of contrasts: the intricate, rhythmic hair texture against the smooth, volumetric musculature of the face; highlights on the forehead and cheekbone against the shadowed jaw and neck.
value structure
The lightest areas are the upper hair mass and the bridge of the nose—pure paper tone. The darkest passages sit in the shadow plane of the right cheek, beneath the jaw, and defining the eye sockets and beard shadow. The face itself lives in an extremely narrow mid-tone band; when squinted, it reads almost as a single value interrupted only by gentle modeling. The paper's warm undertone unifies everything; there are no cool shadows.

edges and brushwork
Edges throughout are soft and blended, created by layering chalk and working it with a tortillon or stump to merge values seamlessly. The hair is rendered with rhythmic, flowing strokes that curve outward to suggest form—each lock follows the underlying structure. Directional marks in the beard suggest texture without hard lines. Contours of the face are suggested through value alone, never sharply drawn; the transition from lit to shadow side is gradual and almost imperceptible.
a working sequence
Establish proportions and center the head
Lightly block in the overall head shape, noting the three-quarter angle and tilt. Mark the vertical center line and horizontal placement of the eyes—they sit roughly one-third down from the top. Indicate the hair mass as a single large form above, and the jaw below.
Define the hair structure
Block in the hair as a solid form using light, consistent pressure. Establish that it's fuller and extends back more on the left side, with ringlets curling around the face. Don't detail yet—just establish the overall silhouette and volume.
Place major facial features
Lightly indicate the position of the eyes, nose, mouth, and jaw line. Check that the nose is properly centered and that the eyes align horizontally. Mark the shadow plane of the face (right side) with a light wash.
Build the face with middle tones
Begin layering chalk to establish the basic flesh tone across the face and neck. Work gently, covering the entire front of the face. Pay attention to how the cheekbone and temple catch more light than the area under the cheekbone and jaw.
Develop the hair texture with rhythmic strokes
Now begin the hair detail with curved, flowing strokes that follow the direction of the curls. Work from light to dark, layering strokes to build form. The strokes should radiate outward and curve back—think of the curls as spirals, not tight lines. Leave the upper areas lighter to suggest how light rakes across the top.
Model the face with shadow and feature definition
Layer darker chalk on the shadow side of the face (right cheek and jaw). Define the eye sockets with a subtle darkening but avoid making them harsh holes. Suggest the nostril and mouth line with minimal marks. The beard appears as shadow more than texture at this distance—suggest it on the jaw and chin with slightly heavier pressure but still soft edges.
Refine subtle transitions and edges
Use a tortillon to blend the transitions between the light and shadow planes of the face. Work very gently here—the shift from lit to shadow should feel almost imperceptible on the cheek and forehead. Refine the eye: suggest the iris with a light touch, and let the socket shadow do most of the work. Soften any hard edges around the nose and jaw.
Final details and character
Add the darkest accents sparingly: deepest in the eye sockets and nostril, along the beard shadow on the chin. Adjust the hair so some locks read crisper and others fade—this creates depth. The overall impression should be quietly dignified, not overworked. Step back frequently and check the three-quarter view hasn't collapsed into profile or full-face.
