Gaius Arrius Antoninus was a Roman senator and jurist active in the last half of the second century AD, who held a number of offices in the emperor's service.
[1] Edward Champlin includes him, along with Gaius Aufidius Victorinus and Tiberius Claudius Julianus, as "marked out as a special intimate of Fronto's."
Upon returning to Rome, Antoninus was appointed quaestor, a traditional Republican magistracy that gave him admission to the Roman Senate.
[6] Afterwards Antoninus served as sevir equitum Romanorum, then was appointed ab actis senatorum before he held the Republican magistracy of curule aedile.
Normally these offices would include the governorship of a province and command of a legion, but Antoninus handled a series of legal and financial responsibilities.
Bernard Remy uses an inscription from Concordia in Regio X of Italia to date his tenure;[7] the city council of that town publicly thanks Antoninus for ensuring the city's supply of wheat in a period of scarcity, which Remy dates to the year 166, when the Antonine plague had reached Italy at the beginning of the new war on the Danube.
