Guardando o Rebanho 

"Guardando o Rebanho" (Watching the Flock), by Portuguese artist António de Carvalho da Silva Porto (1850-1893), depicts a shepherd with a flock of sheep in a rural landscape. The shepherd, with a staff on his shoulder, is dressed in traditional attire while a woman riding a donkey, who may be his companion, is in the background. This scene portrays a traditional shepherd's life and the serene beauty of the natural world, characteristic of the Realist movement. Porto was a highly regarded artist of the 19th century, known for his skillful use of light and realistic portrayal of everyday life in Portugal.
