Sextus Aelius Paetus Catus

Sextus Aelius Paetus Catus (fl. 198-194 BC) or Sextus Aelius Q.f. Paetus Catus (or "the clever one"), was a Roman Republican consul, elected in 198 BC. Today, he is best known for his interpretation of the laws of the Twelve Tables, which is known to us only through the praise of Cicero. Paetus Catus came from a prominent plebeian noble family; his father was a praetor, and his elder brother was another consul, Publius Aelius Paetus.

Sextus Aelius Paetus was apparently the younger surviving son of Quintus Aelius Paetus, a praetor who was one of the many Roman senators killed at Cannae in August 216 BC. Other members of the gens Aelia who rose to high office included Publius Aelius Paetus, who was consul in 337 BC, and Gaius Aelius Paetus, consul in 286 BC.[2]. Both earlier consuls may have been ancestors, or collateral kinsmen, but the connection is not mentioned by the Roman historian Livy.

Paetus's elder brother became Master of the Horse in 202 BC, and consul in the following year. Other members of the family, including Publius's son, succeeded to the consulship in later years.

Little is known of Paetus Catus's political career, or how he acquired the additional cognomen of "Catus". Livy mentions that he was curule aedile in 200 BC, when he imported grain from Africa.

According to an Oxford dictionary of Roman jurists, Paetus Catus's rapid rise from curule aedile to the consulship and censorship was not due to his father's death or his elder brother's successes, but his aptitude for the law. He was apparently nicknamed “catus” meaning “clever” or "the clever one" in recognition of his legal skills. Catus may have given up other aspects of his public career (he is not mentioned in any military action by Livy) to devote his time to the study of law. The Oxford dictionary believes that he may have been the first professional jurist in the history of Rome. (It is not clear if earlier jurists were not professional, or were part-timers, but a Roman paterfamilias of rank and status, or his grown sons, would be expected to defend his family's clients in legal matters. Perhaps the Punic war meant that too many such patrons were away from Rome, and unable to handle legal matters).
