Marcus Porcius Cato (Uticensis)
Known as Cato the Younger.
95 BC 46 BC
This picture of Cato is him as he wouldve appeared circa 50 BC, at the height of the tension between the Roman Senate and Gaius Julius Caesar, who was governing Gaul.
Cato was a follower of the Stoic philosophy and a staunch enemy of Caesar. He was a member of the Optimate faction in the Senate, sometimes referred to as the Boni (Good Men). They were the ultra conservative faction of the Senate, who opposed change of any sort.
Cato was the half-brother of Servilia Caepionis (Caesars mistress), which made him the uncle of Marcus Junius Brutus (Caesars assassin)
He became famous for not wearing a tunic under his toga, because he wanted to emulate the Romans from the birth of the Republic.
Personally, I hate Cato. I strongly believe that the Civil War between Caesar Pompey would have been avoided if it had not been for Catos shortsighted hatred of Caesar, and the fact that he was not willing to compromise.
In 46 BC, whilst besieged inside Utica in North Africa, Cato stabbed himself with his own sword. Unfortunately, his servants found him and stitched him back up. Refusing to allow himself to be pardoned by Caesar, Cato ripped open his stitches and pulled out his own intestines.
