recreation guide

This recreation guide addresses the painting of a Neoclassical portrait by Joseph Wright of Derby, dated 1766. Wright is historically noted for his mastery of chiaroscuro and dramatic lighting, often associated with his candlelit subjects and scientific themes (Source 3). While specific visual details of the sitter 'Robert Vernon Atherton Gwillym' are not described in the provided sources, the recreation should adhere to Wright’s general practice of using brilliant light against shade to create depth and focus (Source 5). The work falls within the tradition of 18th-century British portraiture, which aimed for recognizable likeness and often served as a record of the sitter’s status (Source 8).

materials

item	purpose	modern equivalent
Oil of Copavia	Historical medium for glazing and binding pigments, as noted by Sir Joshua Reynolds in the context of 18th-century practice.	Stand oil or linseed oil mixed with damar varnish
Ultramarine	Primary blue pigment for the initial monochrome underpainting.	Natural ultramarine or high-quality synthetic ultramarine
Black (Ivory or Lamp Black)	Used in the initial grisaille/monochrome stage to establish values.	Ivory black or Mars black
White (Lead White or Titanium White)	For mixing tints in the underpainting and highlights.	Titanium white (for safety) or Flake white (for historical accuracy)
Red and Yellow Earths/Ochres	For glazing and scumbling to introduce warmth and flesh tones after the monochrome stage.	Burnt Sienna, Yellow Ochre, Raw Umber
Canvas	Support for the oil painting.	Linen or cotton duck canvas, primed

preparation

surface prep

Prepare a standard oil ground on canvas. While Wright’s specific ground preparation is not detailed in the sources, 18th-century practice typically involved a white or off-white lead-based ground to allow for luminous glazing. Ensure the surface is smooth to facilitate the fine finish expected in Neoclassical portraiture.

underdrawing

The sources do not specify Wright’s underdrawing method for this specific portrait. However, general advice for copying and study suggests that a sound craftsman must first master the 'alphabet' of the art (Source 1). It is likely that a precise charcoal or thinned oil sketch was used to establish the likeness, as portraiture requires a recognizable record of the sitter (Source 8).

underpainting

Execute a monochrome underpainting (grisaille) using black, ultramarine, and white. This technique is supported by Sir Joshua Reynolds’ description of his own method, which is representative of the period’s high-end practice: 'The first and second paintings are with oil of copavia... the colours being black, ultramarine, and white' (Source 2). This stage establishes the value structure and chiaroscuro effects characteristic of Wright’s work (Source 3).

color palette

Monochrome Base

Black, Ultramarine, White

Establishing the full range of values and forms in the underpainting.

Warm Glazes

Red and Yellow tones (e.g., Vermilion, Yellow Ochre, Red Lake)

Applied as transparent glazes over the dry monochrome to introduce color, particularly in flesh tones and highlights.

Cool Scumbles

Greyed tones, possibly with blue or green undertones

Semi-opaque layers to create 'grey bloom' or coldness in shadows, as described in glazing techniques (Source 2).

composition

While the specific composition of 'Robert Vernon Atherton Gwillym' is not described, Wright’s work is characterized by dramatic chiaroscuro and a focus on light sources (Source 3). In portraiture, the subject should ideally be off-center to avoid exact bisection, with a clear center of interest to prevent the work from becoming merely a pattern (Source 7). The lighting should guide the viewer’s eye, likely focusing on the face or hands, consistent with Wright’s use of brilliant light on shade (Source 5).

step by step

underdrawing→underpainting→refining→finishing

underdrawing

step 01
Sketch the likeness of the sitter on the prepared canvas using charcoal or thinned oil. Focus on accurate proportions and facial features to ensure a recognizable record.
Tip — Ensure the drawing is secure but not so heavy that it shows through the final glazes.
Direct drawing

underpainting

step 02
Paint the entire image in monochrome using black, ultramarine, and white mixed with oil of copavia (or modern equivalent). Establish the full range of lights and darks.
Tip — Mentally extract red and yellow colors, focusing only on value and form (Source 2).
Grisaille

refining

step 03
Allow the monochrome layer to dry completely. This is crucial before applying glazes.
Tip — Rushing this step can cause the glazes to mix with the underpainting, muddying the colors.
Drying

finishing

step 04
Apply transparent glazes of red and yellow tones over the monochrome. Use oil or a mix of varnish and oil. This adds color depth without obscuring the value structure.
Tip — Think of this as tinting an engraving with watercolors (Source 2).
Glazing
step 05
Use scumbling (semi-opaque painting) to adjust highlights and create coldness in shadows if needed. This allows the underlying monochrome to show through.
Tip — Scumbling over darker grounds tends to create a grey bloom or coldness (Source 2).
Scumbling
step 06
Refine details, particularly in the face and hands, to achieve the 'finish' that Wright’s Neoclassical style demands. Avoid 'smallness' or getting too tied down to outlines (Source 1).
Tip — Balance broad masses with fine finish, correcting any tendency to over-model (Source 1).
Detailing

critical techniques

Glazing and Scumbling

Used to build color and depth over a monochrome underpainting. Glazing adds transparent color, while scumbling adds semi-opaque texture and value adjustments. This was a common practice among old masters and Reynolds (Source 2).

Chiaroscuro

Wright is noted for dramatic light and shade. The monochrome underpainting allows the artist to focus purely on these value contrasts before introducing color (Source 3).

Monochrome Underpainting

Using black, ultramarine, and white to establish the image’s structure. This separates the problem of value from the problem of color (Source 2).

common pitfalls

→Applying glazes before the monochrome underpainting is completely dry, which can lead to muddy colors and loss of clarity (Source 2).
→Becoming too tied down to outlines or over-modeling, which can make the painting appear stiff. Wright’s work suggests a balance between broad masses and finish (Source 1).
→Ignoring the value structure by adding color too early. The monochrome stage is essential for establishing the chiaroscuro effects Wright is known for (Source 3).
→Creating exact bisections in the composition, which can make the image static. Aim for off-center placement of the subject (Source 7).

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 visual details of the sitter 'Robert Vernon Atherton Gwillym' (clothing, pose, background) are not described in the sources, so the artist must rely on external references or imagination for these elements.
·Wright’s specific pigment palette for this portrait is not listed; the guide uses Reynolds’ general 18th-century practice as a proxy.
·The exact lighting setup for this specific portrait is not described, though Wright’s general use of dramatic light is noted.
