In Greek mythology, Ethon or otherwise known as "The Eagle Kaukasios" was a gigantic eagle born of the monsters Typhon and Echidna. As punishment for stealing fire from Mount Olympus, Zeus had Prometheus chained to a Mount, where Ethon was set to gnaw on his liver. His liver regrew each night, and then gnawed on each following day.
