Gallio Inscription at Delphi

Fragments of the Gallio inscription from Delphi

Acts says Paul was hauled before the proconsul Gallio during his stay in Corinth. An imperial letter carved at Delphi happens to name Gallio in office in a way that can be dated, by Claudius's titles, to within months — he governed Achaia in AD 51–52. Since proconsuls served one-year terms, this single stone pins Paul's eighteen months in Corinth to a calendar, and from that fixed point the chronology of his whole career is counted backwards and forwards.

What this find showsLuke names the right official, with the right title, in the right province, at a datable moment — and gives Pauline chronology its one absolute anchor.
What it does not proveThe inscription does not mention Paul or the hearing; it fixes when Gallio governed, and the rest follows from Acts' own narrative.
