In page Pankration:

"

The feats of the ancient pankratiasts became legendary in the annals of Greek athletics. Stories abound of past champions who were considered invincible beings. Arrhichion, Dioxippus, Polydamas of Skotoussa and Theogenes (often referred to as Theagenes of Thasos after the first century AD) are among the most highly recognized names. Their accomplishments defying the odds were some of the most inspiring of ancient Greek athletics and they served as inspiration to the Hellenic world for centuries, as Pausanias,[8] the ancient traveller and writer indicates when he re-tells these stories in his narrative of his travels around Greece.[citation needed]
