Perseus Cultural  
  1. A hero of classical mythology who killed the Gorgon Medusa. The god Hermes and goddess Athena helped him in this brave deed by giving him winged shoes, a magical sword, and a polished shield. With the help of these, he swooped down on Medusa from the air, used the shield as a mirror, and cut off her head without looking at it directly — for anyone who looked at a Gorgon turned to stone.
