EPHESUS: The vast theater at Ephesus is not only an impressive monument in itself, still used for concerts and other performances, but also features in a notable episode in the Biblical book of Acts (19:23-41). Supposedly local silversmiths who made their living creating images of Cybele ("Diana of the Ephesians") felt threatened by Paul's success in converting people to Christianity, robbing them of potential customers. Faced with their protest, he decided not to speak at the theater.
