recreation guide

Diego Velázquez’s *St. Paul* (c. 1620) represents a pivotal moment in the artist’s early career, marking his transition from the rigid naturalism of his teacher Francisco Pacheco toward a more fluid, atmospheric style. While rooted in the Caravaggesque tradition of dramatic chiaroscuro and vivid realism, Velázquez’s approach here likely transcends simple imitation. As noted by art historian José Lopez-Rey, Velázquez used Caravaggio’s techniques as a starting point but developed a 'sensuous depiction' and 'atmospheric rendering of spatial depth' that were alien to Caravaggio’s unvaried sheen (Source 2). This work likely exhibits a commanding feeling for both the texture of the subject and the pigment itself, utilizing a variety of brushstrokes—rough or smooth, filmy or thick—that are more akin to Titian than to the hard-edged naturalism of Caravaggio (Source 2). The painting belongs to the Baroque genre, characterized by great drama, rich deep color, and intense light and dark shadows designed to evoke emotion and passion rather than the calm rationality of the Renaissance (Source 6). Velázquez’s early works often served as correctives for students learning to balance broad masses with finish; copying such works helps artists avoid being 'too much tied down to their outline' or inclined to 'over-model' (Source 1). The recreation of this piece requires an understanding of how to manipulate light and shade fluidly, moving beyond the static representation of form to capture the polarity of the divine and the human through atmospheric depth (Source 2).

materials

item	purpose	modern equivalent
Oil paints (Ultramarine, White, Black, Earth tones, Vermilion/Red Ochre)	Primary pigments for underpainting and glazing. Ultramarine and white are specifically noted in Reynolds' method which mirrors old master practices.	High-quality artist-grade oils
Linseed oil or Oil of Copavia	Medium for the first and second paintings to ensure proper flow and drying time, as recommended by Sir Joshua Reynolds for old master techniques.	Stand oil or refined linseed oil
Varnish	Mixed with oil for later glazing stages to gain sufficient mastery over transparent coats.	Dammar varnish or synthetic resin varnish
Canvas	Support for the oil painting, consistent with the medium specified for the artwork.	Linen canvas, primed

preparation

surface prep

The canvas should be prepared with a ground suitable for oil painting. While specific priming details for this exact work are not in the sources, the general practice of the period involved a stable, absorbent ground. The sources emphasize the importance of the 'knowledge of his medium' and being a 'sound craftsman' before beginning (Source 1).

underdrawing

Velázquez’s early works suggest a move away from rigid outlines. The sources advise against being 'too much tied down to your outline' (Source 1). Therefore, the underdrawing should be loose and suggestive, serving as a guide for mass and light rather than a strict boundary. It is likely that Velázquez used a fluid handling of light and shade from the start, rather than hard contours (Source 2).

underpainting

A grisaille (monochrome underpainting) is recommended. The source suggests mentally extracting red and yellow colors to translate what would be left in nature, creating a foundation of values (Source 3). This monochrome layer should be allowed to dry completely before proceeding. This technique allows for the subsequent application of glazes and scumbles to achieve color harmony and depth, a method practiced by old masters far more generally than modern painters often imagine (Source 3).

color palette

Ultramarine

Pure ultramarine pigment

Used in the initial underpainting stages along with black and white to establish values, as per Reynolds' method cited in the sources.

White

Lead white or modern titanium/zinc white

Establishing highlights and values in the grisaille underpainting.

Black

Ivory black or lamp black

Establishing shadows and deep values in the grisaille underpainting.

Red/Yellow Tones

Vermilion, red ochre, yellow ochre, lead-tin yellow

Applied as transparent glazes and semi-opaque scumbles over the dry grisaille to introduce color and warmth, mimicking the 'tinting an engraving' process.

composition

The composition likely employs Baroque characteristics of drama and intense light and dark shadows (chiaroscuro) to evoke emotion (Source 6). Velázquez’s style involves an 'atmospheric rendering of spatial depth' and a 'distinct expression of the polarity of the divine and the human' (Source 2). The figure is likely placed in a naturalistic space with dimension, consistent with the influence of naturalism developed by earlier artists and refined by Velázquez’s unique handling of texture and light (Source 2, Source 5). Specific details of St. Paul’s pose or clothing are not described in the sources, so the composition should focus on the dramatic lighting and the textural contrast between the figure and the background.

step by step

underdrawing→underpainting→first pass→refining→finishing→varnishing

underdrawing

step 01
Sketch the figure loosely on the prepared canvas, focusing on the broad masses and the dramatic lighting rather than fine details. Avoid rigid outlines.
Tip — Ensure the drawing captures the 'dramatic point' and emotional intensity characteristic of Baroque art.
Loose underdrawing

underpainting

step 02
Create a grisaille underpainting using only black, ultramarine, and white mixed with oil of copavia or linseed oil. Establish the full range of values from deep shadows to bright highlights.
Tip — Mentally extract red and yellow colors to focus purely on value structure. Ensure this layer is completely dry before proceeding.
Grisaille

first pass

step 03
Begin glazing and scumbling over the dry grisaille. Apply transparent coats of red and yellow tones using oil as a medium. Use scumbling (semi-opaque painting) to allow the underlying grisaille to show through, creating a 'grey bloom' or atmospheric effect.
Tip — Treat the color application like tinting an engraving with watercolors. Watch for the interaction between the transparent glaze and the opaque underpainting.
Glazing and Scumbling

refining

step 04
Refine the textures and light effects. Use a variety of brushstrokes—rough or smooth, filmy or thick—to achieve a 'sensuous depiction' and 'fluid handling of light and shade'.
Tip — Avoid the 'unvaried sheen' of Caravaggio. Instead, vary the texture of the pigment to enhance the atmospheric depth and spatial realism.
Varied Brushwork

finishing

step 05
Adjust color intensities using complementary color principles. If a color appears too pronounced, soften it by surrounding it with tones of the same color but more intense, or use complementary colors to increase brilliancy.
Tip — Use the laws of coloring to modify the aspect of colors without changing the pigment itself, enhancing the naturalistic effect.
Complementary Color Adjustment

varnishing

step 06
Apply a final varnish to unify the glazes and protect the painting. This step was part of the old master process, often using varnish mixed with oil in later stages.
Tip — Ensure the painting is fully dry before varnishing to prevent cracking or discoloration.
Varnishing

critical techniques

Glazing and Scumbling

Used to build up color and depth over a monochrome underpainting. Glazing involves transparent coats of color, while scumbling involves semi-opaque layers that allow the underpainting to show through, creating atmospheric effects.

Fluid Handling of Light and Shade

Velázquez moved beyond Caravaggio’s static chiaroscuro by varying the quality of brushwork and pigment texture, creating a more sensuous and atmospheric depiction of space and form.

Complementary Color Juxtaposition

Used to modify the appearance of colors. Placing complementary colors next to each other can increase their brilliancy or soften their intensity, allowing for more naturalistic color interactions.

common pitfalls

→Being too tied down to the outline, which can lead to a stiff, unnatural appearance. Velázquez’s style requires a departure from rigid contours (Source 1).
→Over-modeling the forms, which can destroy the atmospheric depth and fluidity of light. The goal is a 'sensuous depiction' rather than hard-edged realism (Source 1, Source 2).
→Using an unvaried sheen for light and shadow, which is characteristic of Caravaggio but not Velázquez. Velázquez varied the texture of the pigment and brushwork to create depth (Source 2).
→Applying color too opaquely without utilizing glazing and scumbling techniques, which are essential for achieving the color harmony and depth found in old master paintings (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 details of St. Paul’s iconography, such as his clothing, attributes (e.g., sword, book), and facial expression, are not described in the sources. The recreation must rely on general Baroque conventions and Velázquez’s known style rather than specific visual evidence from the text.
·The exact dimensions and aspect ratio of the original canvas are not provided, which may affect the compositional balance.
·The specific pigments used by Velázquez in 1620 are not detailed, so modern equivalents are suggested based on general period practices.
