Helios on clouds 

This is a preparatory drawing by the Italian Renaissance artist Correggio, known for his masterful use of light and shadow. It depicts Helios, the Greek god of the sun, soaring through the sky, his body contorted in a dynamic pose. The drawing, executed in black chalk, demonstrates Correggio's skill in capturing movement and anatomy, and it likely served as a study for a larger composition, possibly a fresco or an altarpiece. The work is housed in the Städel Museum, a renowned art institution in Frankfurt, Germany.
