Lucius Junius Gallio Annaeanus
The Delphi Inscription dates Gallio's proconsulship of Achaia to A.D. 51-52.
Acts 18:12-17 mentions Gallio toward the end of Paul's Corinthian stay.
But when Gallio was proconsul of Achaia, the Jews made a united attack on Paul and brought him before the tribunal, saying, “This man is persuading people to worship God contrary to the law.” But when Paul was about to open his mouth, Gallio said to the Jews, “If it were a matter of wrongdoing or vicious crime, O Jews, I would have reason to accept your complaint. But since it is a matter of questions about words and names and your own law, see to it yourselves. I refuse to be a judge of these things.” And he drove them from the tribunal. And they all seized Sosthenes, the ruler of the synagogue, and beat him in front of the tribunal. But Gallio paid no attention to any of this.
