Somnambule

Albert von Keller's Somnambule (1886) depicts a sleepwalker — a figure in the trance-like state between sleep and waking that fascinated both medical science and occultist circles in the late nineteenth century. Somnambulism was investigated by Jean-Martin Charcot at the Salpêtrière hospital in Paris and connected to the broader study of hysteria, hypnosis, and altered consciousness. Von Keller, embedded in Munich's spiritualist circles, approached somnambulism as both medical phenomenon and mystical state — the body walking without conscious control suggesting a dimension of human experience beyond ordinary waking life.

Von Keller renders the sleepwalker in the characteristic mode of his boundary-state subjects: the figure is depicted in a state between sleep and waking, its movement automatic and unconscious. His pale, cool palette for the somnambule contrasts with darker surrounds, creating the uncanny atmosphere of a figure moving through space without awareness. The face's blank expression — present but not seeing — and the figure's mechanical movement are conveyed through careful observation of pose and expression.
