Moonlight falls across the figure in Somnambula, painted in 1871 by Ivan Kramskoi using oil on canvas. A woman dressed in a pale nightgown stands outdoors at night, her posture rigid and her arms extended slightly forward, eyes closed as if moving while asleep. The dark garden surrounds her, with a house dimly illuminated in the background, emphasizing her isolation and vulnerability.

The artist employs a restrained palette dominated by deep greens, blues, and soft whites, using sharp light contrasts to highlight the subject's face and garment against the enveloping darkness. Produced during a period of growing interest in psychological and nocturnal themes in Russian art, this work reflects the broader 19th-century fascination with sleepwalking as a subject. Somnambula measures 135 by 86 centimeters and is held in the Tretyakov Gallery. The painting exemplifies Kramskoi's careful attention to naturalistic detail and atmospheric effects, characteristic of his mature style.
