Here is a dark Baroque masterpiece. Using a polished shield as a mirror, Perseus has just severed the dreadful head of Medusa, a gorgon capable of turning anyone who sees her into stone. Medusa’s head was subsequently used by Perseus as a weapon to slay the sea monster sent to devour Andromeda–but the weapon proved too dangerous for him to keep so he gave the head to Athena, goddess of victory and wisdom. She set it on her shield (or sometimes her breastplate) and the Gorgoneion thus became a symbol of divine protection and luck as well as a charm for warding off evil.
Through the artist’s imagination, we are allowed to see what Perseus is not: the horrible head of the demigoddess with her countenance contorted in mortal outrage. Despite her death, the many serpents which make up her hair remain alive and infuriated. One even bites her forehead in pique. Where her blood pours on the ground, serpents and worms spring to life. Spiders, scorpions and lizards appear in order to abet the general creepy horror of the scene (as do the stormy clouds and desolate landscape.
Rubens was the master of using color and motion to express the sensual and the grotesque. The full dynamism of his style is evident in this grisly tableau which simultaneously evokes the drama of earlier Medusa paintings by Da Vinci & Carravagio while also bringing some of the detail and imagination of Flemish still life composition to play.
