Oil painting of a landscape

Oil on canvas from the second half of 1800 with frame of the same period. Hilly landscape with a mill on the bank of the river. In the background a Roman aqueduct that crosses it. The sky, sometimes cloudy, touches the ruins of a small fortress now collapsed. On the other side, a shepherd watches his flock from afar. Unsigned, in the first canvas, restored. The measurements of the painting alone without the frame are: 127 cm in length and 70 cm in height.
