Keeps watch over Alberich's ring

surface prep

The surface should be prepared to accept oil paint, likely involving a ground that allows for the 'vast capacity' of the medium to express vitality without merely tricking the eye (Source 1). While specific priming methods for Rackham are not detailed in the sources, traditional oil painting practice suggests a stable ground to prevent cracking, adhering to the principle that the quality of the oil and ground leads to a strong paint film (Source 2).

underdrawing

Begin by sketching the subject onto the canvas with charcoal or thinned paint, as is traditional in oil painting techniques (Source 2). Rackham, as an illustrator, likely visualized the pictorial episode and sketched the scene to determine how figures are grouped and accessories placed to complete the pictorial arrangement (Source 3). The underdrawing should establish the main structural lines and color masses, paying attention to the rhythmic power of lines that underlie the expression of the picture (Source 4).

underpainting

Apply an initial layer of paint, ensuring it is 'lean' (less oil) to allow for proper drying and to adhere to the 'fat over lean' rule (Source 2). This layer should establish the basic forms and values, serving as a foundation for subsequent layers. The artist should avoid attempting more than the medium is capable of doing in this stage, focusing on the vital qualities of the material (Source 1).

Fat over lean

Each additional layer of paint should contain more oil than the layer below to allow proper drying and prevent cracking.

Rhythmic composition

Use abstract lines, such as right angles and curves, to create emotional significance and guide the viewer’s eye.

Simultaneous contrast

Place contrasting colors in close proximity to enhance visual intensity and create a shimmering appearance.
