Félix Vallotton's 'Le Sommeil' (1908) portrays a nude woman asleep on a dark-blue sofa. The painting's muted tones and simplified forms create a mood of quiet intimacy.

Félix Vallotton, a Swiss and French painter and printmaker associated with the group Les Nabis, created 'Le Sommeil' in 1908. This oil on canvas depicts a nude woman asleep on a large, dark-blue cushion or sofa. The composition is simple, with the figure dominating the space. Her body is rendered in soft, muted tones, contrasting with the bolder colours of the cushions and the background. The woman's pose is relaxed, with her head resting on her arms and her legs slightly bent. A book lies open on the floor near the foot of the sofa, suggesting a moment of interrupted reading before sleep. Vallotton's style is characterised by its flatness and simplified forms, a departure from traditional academic painting. The influence of Japanese prints, a common source of inspiration for Les Nabis, is evident in the flattened perspective and the emphasis on outline. The painting's subdued palette and intimate subject matter contribute to its overall mood of quiet contemplation. 'Le Sommeil' is a study in repose, capturing a private moment of vulnerability and peace.
