Publicola

He was a man endowed with every virtue, but most excellent in war. Designing to kill Porsena, he stole into his camp, wearing a Tuscan habit, and using a speech to correspond. After walking around the tribunal where the king was sitting within others, not knowing him certainly, and fearing to inquire about him, he drew his sword and slew that one of the group whom he thought most likely to be the king.

Upon this he was seized, and was being questioned, when a sort of pan containing live coals was brought to Porsena, who was about to offer sacrifice. Mucius held his right hand over the flames and, while the flesh was burning, stood looking at Porsena with a bold and steadfast countenance, until the king was overcome within admiration and released him, and handed him back his sword, reaching it down to him from the tribunal. Mucius stretched out his left hand and took it (on which account, they say, he received the surname of Scaevola, which means Left-handed).
