The collection in Room 406 is organized around the landscape genre, which dominated both artists' output, while also demonstrating their divergent paths within Impressionism. Sisley's works in the room span 1872 to 1884, tracing the development of his Impressionistic manner through depictions of the French provincial countryside. Pissarro's works cover a broader chronological range, from 1873 to 1903, and include his characteristic urban views of Paris alongside rural subjects. A notable exception in the Pissarro holdings is Still Life with a Coffeepot (1900), a rare venture into still life. The installation thus juxtaposes Sisley's lyrical, consistently rural focus with Pissarro's more varied topography, encompassing both pastoral scenes and the dynamic modern city. This curatorial approach aligns with scholarly characterizations of the two as the purest landscape painters among the core Impressionists, while acknowledging Pissarro's greater stylistic range and his late turn to urban series painting.
