Andalusian Bulls 

Rosa Bonheur, known for her animal studies, captures the power and strength of Andalusian bulls in this monochrome sketch. The two bulls, rendered in charcoal and chalk, stand in a field, their muscular forms emphasized by the artist's careful attention to detail. Bonheur's depiction of these animals, with their horns and powerful legs, speaks to her lifelong fascination with the natural world, while the simple background allows the viewer to fully appreciate the subject of the artwork.
