Impressionist painting - Signed seascape - 19th century Italian school

Hello. I am offering a romantic seascape in an Indian summer atmosphere at the end of the day. This work is dated 1850 under a signature to be deciphered at the bottom left. This lively scene is the work of a talented painter of the 19th century Italian school. This oil painting mounted on a thick wooden panel most likely represents a landscape in the glowing sun of northern Italy. At the foot of a low mountain range, a tributary of the Po River flows peacefully. In the foreground on the left appear 3 Italian peasant women seen from behind in their traditional 19th century costumes. The shawl they wear on their backs corresponds well to a Western work and not to an Orientalist representation despite the long tray worn on the head by the central character. These 3 characters are heading towards the background. In the distance, native fishermen with their boats returning from fishing are located on the bank, while to the right, boaters enliven this scene. The tiny boats depicted with their figures give a certain depth to the work. Hidden by a wooden house, we also notice a bridge in the distance to cross from one bank to the other, which also proves that we are not in front of a mountain lake landscape as can be found in regions of the Atlas in North Africa for example. Two guard towers are located at the end of the bridge on the other side of the bank, guardians of the passage and the population in a region certainly full of history. These two towers of a certain height were probably to prevent the crossing from one bank to the other during regional conflicts. Dimensions of the frame: 55.5 cm X 42.5 cm. Dimensions of the work: 40.5 cm X 32 cm. Estimate of an auctioneer from Catawiki: between 350 and 400 euros (see photo).
