Barrage de la Machine de Marly

Barrage de la Machine de Marly of 1876 depicts the hydraulic weir on the Seine near Marly-le-Roi — the modern replacement for Louis XIV's famous wooden machine, which had itself been celebrated as a wonder of engineering in the seventeenth century. By Sisley's time a steam-powered installation had replaced the original mechanism, but the barrage it operated created a distinctive visual subject: the controlled fall of water over the weir structure, the churning pool below, the particular light effects produced by moving water in a confined channel. Sisley was living at Marly between 1875 and 1878 and was systematically documenting the landscape of the Seine valley around the town, including both its picturesque features and its hydraulic engineering infrastructure. The 1876 date makes this canvas contemporary with his famous flood paintings at Port-Marly, painted just a few months earlier during the Seine's extraordinary spring inundation. The contrast between the controlled engineering of the barrage and the uncontrolled flooding downstream represents two aspects of Sisley's engagement with the Seine's hydraulic character in a single year.

Oil on canvas. Water engineering structures — the barrage's horizontal concrete or stone elements — give Sisley a geometric counterpoint to the organic movement of water. The barrage reflects sky and light into the foreground, creating a complex chromatic surface in which mechanical and natural elements intermingle.
