Arrhichion (also spelled Arrhachion, Arrichion or Arrachion) of Phigalia (Greek: Αρριχίων ο Φιγαλεύς) (died 564 BC) was a champion pankratiast in the ancient Olympic Games.
But in relaxing the tension of his legs he failed to forestall the scheme of Arrichion; for the latter kicked back with the sole of his right foot (as the result of which his right side was imperiled since now his knee was hanging unsupported), then with his groin he holds his adversary tight till he can no longer resist, and, throwing his weight down toward the left while he locks the latter’s foot tightly inside his own knee, by this violent outward thrust he wrenches the ankle from its socket.
[6]Philostratus of Athens writes in his Gymnasticus that Arrichion's failure to submit to his opponent was the result of his trainer, Eryxias, shouting to him, "What a noble epitaph, 'He was never defeated at Olympia.
[11] Arrhichion was the subject of a poem, "Arrichion", by Jeanette Threlfall, in which the poet laments the fact that the athlete lived and died before St. Paul brought Christianity to Greece.
[12][13] Arrhichion's fatal fight would be parodied in Monty Python and The Holy Grail, where the Black Knight has all his limbs chopped off by King Arthur but refuses to give up, despite being a legless and armless torso, until eventually calling a draw.
