Mucius was a legendary hero from Rome's earliest history. When the Etruscan Lars Porsenna of Clusium laid siege to Rome, brave Mucius entered the city but failed in his attempt to kill Porsenna. When he was brought before Porsenna, Mucius showed no fear and to demonstrate his contempt for pain and torture, he placed his right hand in a fire. Impressed by his fearlessness, Porsenna released him. Mucius, thereafter, was nicknamed Scaevola, "left hand." On gems, the story is not particularly common, and normally only the single figure of Mucius with his hand in the fire is shown.
