He came from a distinguished old family that traced its lineage back centuries to the mythical founding fathers of Rome. His ancestor Sergestus was said to have fled from the East to Italy with Aeneas after the Trojan War, before the city of Rome even existed. Among his blue-blooded forebears, his great-grandfather was a hero of the war against Hannibal, with the extra claim to fame of being the first man known to have entered combat with a prosthetic hand – probably just a metal hook that replaced his right hand, lost in an earlier battle.
