Gaius Ateius Capito

Capito was a son of the tribune of the same name, and was educated as a jurist by Aulus Ofilius. He was active as a jurist and a senator. Capito was a strong proponent of the principate which brought him in opposition to Marcus Antistius Labeo. In the year 11, he became curator aquarum and was responsible for water supply and regulation throughout the city of Rome. Four years later he and Lucius Arruntius were entrusted by Tiberius to work on a plan to confine the river Tiber after heavy floods, but the project was not carried out due to heavy resistance from the populace. Capito is attested as witnessing a number of legal documents. One was a senatus consultum that prohibited Senators, equites, and their descendants from actively participating in gladiatorial matches. In another, he was one of seven witnesses of the Senatus consultum de Cn. Pisone patre, the Roman Senate's official act concerning the trial and punishment of Gnaeus Calpurnius Piso, dated 10 December 20 CE. His successor in the office of curator aquarum was Tarius Rufus. He does not appear to have had any descendants. G.V. Sumner has speculated, based on the names, that Capito adopted the son of Sejanus, Capito Aelianus.

All of Capito's works are lost and are only known by their titles through quotes by later authors. Works known to have existed include: • De pontificio iure ("About pontifical law"), at least six books about laws concerning the pontifices • De Indiciis Publicis ("On Public Trials"), recorded by Aulus Gellius, who claims that it mentioned the treason trial of Claudia during the First Punic War. • De iure sacrificiorum ("About sacrificial law") • Coniectanea ("Miscellaneous"), at least 9 books about various themes • De officio senatorio ("About the senatorial office") • One work of unknown title about the auguries • Epistulae ("Letters")
