Marcus Porcius Cato Uticensis was born in 95 BC, the son of a father who shared his name and Livia. His childhood ended abruptly when he and his sister Porcia were orphaned before he turned four years old. The children moved into the household of their maternal uncle, Marcus Livius Drusus. After Drusus died during the Social War in 91 BC, they entered the home of Mamercus Aemilius Lepidus Livianus. This man was the older brother of their mother. They lived with a half-brother named Gnaeus Servilius Caepio and two half-sisters from Livia's first marriage to Quintus Servilius Caepio. Cato formed a close bond with his half-brother Caepio and his elder half-sister Servilia. Servilia would later marry Marcus Junius Brutus and become the mistress of Julius Caesar.
Stories about his early life remain unreliable but serve to establish his character. One tale claims that Quintus Poppaedius Silo threatened to hang him out of a window unless he supported Italian citizenship. Cato supposedly remained silent under this threat. Another story suggests he asked his tutor for a sword to assassinate Sulla during the proscriptions. These anecdotes likely exaggerate his youth to foreshadow his adult rigidity. At age sixteen, he joined the quindecimviri sacris faciundis, a board of priests interpreting the Sibylline Oracles. This prestigious honor placed him at the center of the senatorial elite.
The Honest Quaestor
Cato returned to Rome in early 65 BC to stand for the quaestorship. He took office on December 5th of that year as one of the urban quaestors. The treasury staff had long delegated complex financial work to clerks, creating widespread corruption. Cato prosecuted several clerks and fired others who failed to meet standards. Even after one clerk was acquitted following intervention from a censor, Cato refused to rehire him. He began collecting state debts and made prompt payments to creditors. He cooperated with Julius Caesar, then acting as a prosecutor, to challenge legal immunity given to men who received bounties for killings during the Sullan proscriptions.
On his final day in office, Cato discovered fraudulent records entered by Marcus Claudius Marcellus. He stormed back to erase them before the term ended. He spent five talents, roughly four percent of his inheritance, to copy all treasury archives from Sulla's time to his own day. Plutarch reported that he taught men that a city could be rich without treating its citizens unjustly. His administration brought the quaestorship greater esteem than the senate itself. This reputation for honesty allowed him to enter public life with an unblemished record.
