Acts 18:12

“And when Gallio was the deputy of Achaia, etc.] This province, which was now become a Roman one, Pliny the younger f929 calls true and mere Greece; it went by the name of Aegialus f930, and now it is called Livadia: it has on the north the country of Thessaly, and on the west the river Acheloo, or Aracheo, on the east the Aegean sea, and on the south Peloponnesus, or the Morea. Gallio, who was now deputy of it, was brother to L. Annaeus Seneca, the famous philosopher, who was preceptor to Nero; his name at first was M. Annaeus Novatus, but being adopted by L.

Yet one thing he lacked! But he knew it not and had no concern about it. Acts 18:15”

“18:12-13 The governor of Achaia, Junio Gallio, was the older brother of the Roman philosopher Seneca (Seneca was a tutor to Emperor Nero). An inscription indicating that he was governor around AD 51–52 helps to date Paul’s visit in Corinth to about that time.”
