Two lying sheep 

This graphite drawing, "Two Lying Sheep," by Friedrich Wilhelm Hirt, depicts a ram and a lamb resting in a field. The artist used subtle shading to create a sense of volume and texture, capturing the fluffy wool of the sheep. The composition is simple yet effective, highlighting the peaceful scene of the animals at rest. The drawing's delicate lines and nuanced shading suggest a study of animal anatomy and a careful observation of nature. This piece can be found in the Städel Museum.
