I haven’t been to Positano but apparently the church is still there and one of the sights of the town—a medieval church later redecorated, with a Byzantine icon of the Black Madonna and a 1599 painting of the circumcision of Jesus (not a common theme for paintings). If the villa was found 24 meters below the church I assume they could uncover the Roman art without damaging the church.
Wow, the church sounds unique with a black Madonna, and a painting of The LORD being circumcised. I wonder why they painted a black Madonna. It would be fun to visit it. Thanks for the interesting info.
