18:12 Gallio. Gallio’s name, as proconsul of Achaia, has actually been found on an inscription at Delphi in Central Greece. He was a son of the famous rhetorician Lucius Junius Gallio and brother of the equally famous philosopher Seneca, and was appointed proconsul of Achaia by the emperor Claudius about A.D. 51. Corinth was the capital of Achaia, which included southern Greece, south of Macedonia.
