Focus on In a Roman Osteria and explain the Description.
The setting is in the interior of a Roman osteria. In the forefront, there is a table with three customers: a young man is facing two young women. The one on the left of the man wears a headscarf in the typical garb of married Roman women at the time. The man is seen turning toward the onlooker with an angry expression, whereas the woman at his left is looking with a smiling one, and the (presumably slightly older) other woman looks amused in the same direction. A cat sits to the left of the young woman, silently judging the onlooker.
The painter depicted himself in the background, sitting at a table talking with two friends; his back is turned to the viewer.
