Six studies of male figures in various prone and supine positions 

This is a plate from a series of anatomical studies by the Flemish Baroque painter Peter Paul Rubens. It depicts six male figures in various prone and supine positions, demonstrating Rubens's masterful understanding of the human form. This series of anatomical studies, originally created as drawings, was later adapted by the engraver Pieter de Jode, highlighting the importance of anatomical accuracy in Rubens's art. The detailed rendering of musculature and posture in these studies served as a guide for artists seeking to portray the human body with realism.
