recreation guide

The Last Supper (c. 1495–1498) is a monumental mural by Leonardo da Vinci, housed in the refectory of the Convent of Santa Maria delle Grazie in Milan. It depicts the moment Jesus announces that one of his apostles will betray him, capturing the distinct reactions of shock and anger among the twelve apostles (Source 1, Source 2). The work is celebrated for its mastery of perspective, handling of space, and complex display of human emotion, marking a pivotal transition into the High Renaissance (Source 2). Unlike traditional frescoes, Leonardo employed an experimental technique using tempera on a dry wall sealed with gesso, pitch, and mastic, allowing for the slow, deliberate revisions characteristic of his process but resulting in rapid deterioration (Source 1, Source 2, Source 3).

estimated time

60-100+ hours over several months (reflecting Leonardo's inconsistent schedule of painting intensely for days then stopping for weeks) (Source 3)

preparation

surface prep

Prepare the surface by sealing it with a double layer of gesso, pitch, and mastic. This creates a ground suitable for tempera rather than fresco. Apply an undercoat of white lead (or a bright white modern equivalent) to enhance the luminosity and brightness of the subsequent tempera layers. This method, described by Cennino Cennini, was chosen by Leonardo to allow for the luminosity and chiaroscuro effects he desired, which are difficult to achieve with water-soluble fresco colors (Source 1).

underdrawing

Construct the human figures with a keen sense of anatomy and structure. Leonardo emphasized the importance of understanding the bony structure and muscle function to render the human form successfully (Source 5). Given the complexity of the apostles' reactions, detailed preparatory drawings focusing on gesture and expression are essential. Leonardo reportedly struggled with depicting the faces of Christ and Judas, suggesting extensive study and potential use of models (Source 3).

underpainting

Apply a white lead undercoat over the sealed gesso/pitch/mastic ground. This layer is critical for enhancing the brightness of the tempera applied on top, facilitating the high luminosity Leonardo sought (Source 1).

color palette

Bright, luminous tones

Tempera pigments over white lead ground

General use to achieve greater luminosity and intensity of light and shade (chiaroscuro) than fresco allows (Source 1)

Contrasting hues

Complementary colors mixed with grey to avoid crudity

Creating harmony and distinctness in remote planes, consistent with color contrast principles (Source 8)

composition

The composition centers on the moment of announcement, organizing the twelve apostles to display varied degrees of anger and shock (Source 1). The arrangement relies on mastery of perspective and spatial handling to create depth and focus (Source 2). While specific visual details of clothing or background objects are not described in the provided sources, the composition is noted for its complex display of human emotion and motion (Source 2). The grouping of figures likely follows principles of visual ordering, using line and shape to guide the eye (Source 6).

step by step

underdrawing

step 03
Sketch the figures with attention to anatomical construction and gesture.
Tip — Focus on the 'hidden construction' of the form to ensure successful rendering of action and character (Source 5).
Artistic anatomy and construction

underpainting

step 02
Apply an undercoat of white lead to the sealed surface.
Tip — This layer is crucial for the brightness of the final tempera layers (Source 1).
Luminosity enhancement

first pass

step 04
Apply tempera paints in layers, working slowly to allow for changes.
Tip — Leonardo favored this medium for its ease of revision, unlike fresco (Source 1).
Tempera application

refining

step 05
Develop the chiaroscuro effects to create intensity of light and shade.
Tip — Aim for greater luminosity than possible with fresco (Source 1).
Chiaroscuro

finishing

step 06
Finalize the expressions of the apostles, ensuring distinct reactions of shock and anger.
Tip — Leonardo worked in intense bursts, sometimes painting from dawn to dusk, then stopping for days (Source 3).
Characterization

surfaceprep

step 01
Seal the wall or panel with a double layer of gesso, pitch, and mastic.
Tip — Ensure the surface is dry and stable to prevent flaking, a known issue with this method (Source 1, Source 3).

critical techniques

Tempera on dry wall

Used instead of fresco to allow for slow work, revisions, and greater luminosity/chiaroscuro. Applied over gesso, pitch, and mastic with a white lead undercoat.

Chiaroscuro

Leonardo sought greater intensity of light and shade than fresco could provide, using the tempera medium to achieve this luminosity.

Anatomical Construction

Understanding the bony structure and muscle function is essential for rendering the human form with success, particularly for the complex gestures and expressions of the apostles.

common pitfalls

→Rapid deterioration: The tempera-on-gesso method is risky and subject to mould and flaking, as noted by Cennino Cennini and observed in the painting's history (Source 1, Source 3).
→Inconsistent schedule: Leonardo's habit of working intensely then stopping for days may frustrate patrons or collaborators, as seen with the prior of the convent (Source 3).
→Difficulty with facial expressions: Depicting the specific emotions of Christ and Judas was a particular challenge for Leonardo (Source 3).

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 color palette details (exact pigments used for robes, skin tones) are not provided in the sources.
·Detailed compositional layout (exact positioning of each apostle, background architecture details) is not described in the sources, only general reactions and perspective mastery.
·Specific brushwork techniques or glazing methods beyond the general tempera application are not detailed.
·The exact identity of models used, other than the potential use of the prior for Judas, is not specified.
