brave resistance to authority or rebellion against the established order of the universe
a. from Greek mythology: Prometheus was a demigod known for his cunning. Having been tricked by Prometheus, Zeus withheld fire from mankind. In response, Prometheus went to Mount Olympus and stole some fire, which he gave to man. Zeus punished him by chaining him to a rock; each day, an eagle came and ate out his liver, which grew back each night. He was eventually rescued by Hercules.
