Acts 18:12-17

Gallio was the son of Marcus Annaeus Seneca, a Spanish orator and financier, and the elder brother of Seneca, the philosopher and tutor of Nero. Lucius Junius Gallio, a rich Roman, adopted Gallio, naming him Lucius Junius Gallio Annaeus. Gallio's name appears on an inscription at Delphi that refers to the 26th acclamation of Claudius as emperor. This places Gallio in office in Corinth between A.D. 51,53. He was apparently proconsul from May 1,51, to May 1,52, though dates a year later are possible. The date gives evidence from outside the Bible for the time Paul was in Corinth and founded the church there.

Finding the climate at Corinth unhealthy, Gallio apparently welcomed the opportunity to return to Rome, where he counseled Nero until he and Seneca joined a conspiracy against the emperor. First Seneca died; then Nero forced Gallio to commit suicide about A.D. 65. See Achaia; Corinth; 1,2Corinthians; Paul; Roman Empire.
