Portrait of the artist with oil lamp

This self-portrait with oil lamp, painted around 1902, is one of Rousseau's most intimate self-images. The lamp's warm glow creates an unusual nocturnal intimacy rare in his work, suggesting a private, almost confessional mood. Rousseau was at this point holding his famous soirées familiales — home entertainments with music and poetry — in which he participated with the same earnest seriousness he brought to his painting. Held at the Musée Picasso, the portrait reflects Picasso's personal fascination with Rousseau's unselfconscious dignity, qualities the trained avant-garde artist found simultaneously enviable and mysterious.

The artificial lamplight creates a warmer palette than Rousseau's daylight works, with ochres and amber tones dominating. His customary flatness is softened slightly by the directional light source, though he still avoids deep cast shadows in favor of simplified, evenly lit planes.
