Torture of Prometheus is an oil painting by Salvator Rosa, an Italian Baroque painter active in Naples and Rome, executed c. 1646-1648.
The scene depicts a story from Greek mythology, wherein Prometheus, one of the Titans, is punished by Zeus for having provided humanity with fire.
The punishment was to chain Prometheus to a rock in the Caucusus, and that an eagle would arrive and feast on his liver.
Daily his wounds would heal, his liver regenerate, and the eagle would return to again torture him.
The scene has been represented by other contemporary painters such as Rubens and Jordaens, but they typically show the beginning of the eagle's attack, while Rosa has chosen to depict the event in the midst of a gory disembowelment.
