Gaius Mucius Cordus, better known with his later cognomen Scaevola, was an ancient Roman youth, possibly mythical, famous for his bravery.
In 508 BC, during the war between Rome and Clusium, the Clusian king Lars Porsena laid siege to Rome. Gaius Mucius Cordus, with the approval of the Roman Senate, sneaked into the Etruscan camp with the intent of murdering Porsena. Since it was the soldiers' pay day, there were two similarly dressed people, one of whom was the king, on a raised platform speaking to the troops. This caused Mucius to misidentify his target, and he killed Porsena's scribe by mistake. After being captured, he famously declared to Porsena: "I am Gaius Mucius, a citizen of Rome. I came here as an enemy to kill my enemy, and I am as ready to die as I am to kill. We Romans act bravely and, when adversity strikes, we suffer bravely." He also declared that he was the first of three hundred Roman youths to volunteer for the task of assassinating Porsena at the risk of losing their own lives.
"Watch", he is said to have declared, "so that you know how cheap the body is to men who have their eye on great glory".
