A proconsul of Archaia, under the emperor Claudius, in the time of Paul, Acts 18:12-17 . He was the elder brother of the philosopher Seneca, who describes him as uncommonly amiable and upright. His residence was at Corinth; and when the Jews of the city made an insurrection against Paul, and dragged him before the judgment seat, Gallio refused to entertain their clamorous and unjust demands. The Greeks who were present, pleased with the rebuff the persecuting Jews had received, fell upon Sosthenes their leader, and beat him upon the spot, a mode of retribution that Gallio ought not to have allowed. Like his brother Seneca, he suffered death by order of the tyrant Nero.
