A minimalist study in colour and form, this circular composition by Rupprecht Geiger explores the intense, radiant properties of red.

Rupprecht Geiger, a German painter and sculptor, dedicated much of his career to the study of colour and its psychological impact on the viewer. His work often centres on the exploration of light, space, and the physical presence of pigment. In 867-97 (Vulcano), Geiger employs a circular format to contain a singular, intense field of colour. The composition is stripped of representational elements, allowing the viewer to engage directly with the saturation and temperature of the red hues. Geiger was a founding member of the ZEN 49 group in Munich, which sought to re-establish connections with international modernism after the Second World War. His approach to painting is characterised by a reduction of form, where the canvas becomes a vessel for pure chromatic energy. The circular shape, or tondo, is a recurring motif in his practice, providing a self-contained environment that avoids the traditional constraints of rectangular framing. By removing the horizon line and other spatial markers, Geiger forces the eye to focus on the subtle shifts in tone and the luminosity of the surface. The title, Vulcano, suggests a connection to the elemental power of fire and heat, themes that appear frequently in Geiger's later works. The application of paint is precise, creating a smooth, almost atmospheric quality that invites contemplation. This piece is representative of his mature style, where the artist moved away from gestural brushwork toward a more controlled, meditative application of colour. Through this reductionist approach, Geiger achieves a sense of expansion, as if the colour itself is radiating outward from the centre of the circle. This print captures the specific intensity of the original acrylic application, maintaining the balance between the deep, earthy base and the lighter, more luminous upper section of the sphere.
