the Gallio Inscription from Delphi that mentions Gallio

Gallio’s name (18:12-17) appears on an inscription at Delphi that refers to the twenty-sixth acclamation of Claudius as emperor. This places Gallio in office in Corinth between AD 51 and 53. He was apparently proconsul from May 1, 51 to May 1, 52 though dates a year later are possible. This dating gives evidence from outside the Bible for the time Paul was in Corinth and founded the church there.
