In Greek mythology, the three Gorgon sisters were dreadful monsters. Their hair was made out of snakes whose gaze turned anyone who saw them into stone. The most famous Gorgon, Medusa, was killed by the hero Perseus. He put her head on his shield and used it to petrify his enemies. The Greeks used images of Gorgon faces as protective charms for homes, and our posters may well serve the same purpose for your abode.
