Horses’ heads and human head in profile, with detail of horse’s eye and nose 

This etching by Peter Paul Rubens, a prominent figure in the Baroque period, features detailed studies of a human and horse head in profile. The composition showcases Rubens's masterful understanding of anatomy, evident in the precise rendering of musculature and bone structure. This study, likely intended for artistic exploration rather than a finished work, is a testament to Rubens's dedication to anatomical accuracy and his influence on subsequent generations of artists.
