Herdsman Crossing a River 

Francesco Casanova's "Herdman Crossing a River" depicts a pastoral scene with a herdsman leading a flock of sheep and a large cow across a river. The drawing features a detailed landscape background with ruins, a small village, and a distant view. Casanova was known for his drawings of animals, and the work reflects his skill in capturing the movement and life of the animals. The drawing likely dates to the late 18th century when Casanova was at the height of his artistic career. The work is rendered in brown ink and wash, with a delicate and expressive style.
