We were only in Athens for a day (cruise ship stop) and there certainly was quite a lot to see.
On another day, we were in Ephesus. It was quite awesome indeed. The Theatre of Ephesus is mentioned in the Bible (Acts 19:23-41), the theatre was the site of the riot of silversmiths who made figures of pagan idols like Artemis (Diana). A silversmith by the name of Demetrius was named to have rallied fellow silversmiths to his cause. They stirred up the people of Ephesus, who were confused, and all rushed to the theatre. Acts 19:34 records the people in the theatre as chanting "Great is the Artemis (Diana) of Ephesus!"
