Whether from comics, cartoons, video games or movies, almost everyone knows the superhero Iron Man (the iron Man). Well, the first Iron Man in history, or rather the Iron Hand, was the Roman Marcus Sergius .
Marcus Sergius, great-grandfather of Lucius Sergius Catilina (Catilina) , was a general of Rome who fought in the Second Punic War against Hannibal. He fought side by side with the legionnaires and was wounded 23 times until his right hand was amputated. The normal thing would have been to withdraw from the front line, but Marcus's idea was to continue fighting. He put himself in the hands of the best blacksmiths and had a «prosthesis » to be able to hold the shield. They did so and he returned to battle…until he was taken prisoner by the Carthaginians. After 20 months of captivity he managed to escape and returned to Rome.
Already retired from the army, he tried to be a priest but couldn't… he didn't have both hands. The prosthesis only served to hold the shield.
