Theme of Perseverance in Perseus and Medusa

No great hero ever became a hero without a more than a little perseverance. Despite all the barriers in Perseus' way, still he bravely trudges forward. Even though the task of delivering Medusa's head to his king seems impossible, he never quits. In a way, he was like the Jack Bauer of the ancient world. He gets the job done no matter what it takes.
