In Théodore de Banville écrivant et fumant la cigarette, we see a portrait of the poet Théodore de Banville. He is depicted seated at a table, with a cigarette in hand, deep in thought. The colors are muted, with browns and grays dominating the palette, creating a somber yet intimate atmosphere.

The background is simple, focusing the viewer's attention on Banville's contemplative expression. The painting is executed in oil on canvas, a common medium for Édouard Manet. The brushwork is loose and fluid, characteristic of the Realism style, allowing for a natural representation of the subject. Manet captures the texture of Banville's clothing and the smoke from the cigarette with remarkable detail.

The dimensions are approximately 65 x 54 cm, making it a medium-sized portrait. Édouard Manet was a pivotal figure in the transition from Realism to Impressionism. This portrait of Théodore de Banville reflects Manet's interest in capturing modern life and the personalities within it. An interesting fact about this work is that it was created during a time when Banville was an influential literary figure in France, showcasing the connection between art and literature in the 19th century.

Manet's choice to depict Banville in a relaxed, candid moment adds depth to the portrayal of the poet.
