I am so grateful I was able to make the trip. It brought the era of Paul into focus. It was amazing. One of my favorite photos of Ephesus was of a pile of clay tile that had been excavated. We could also see the clay tile in the ground. The tile served as their water system. They had running water in their homes, as well as indoor toilets.
There was a domed roof still standing. I think the mortar was superior because of the ash.
Nevertheless, it was a very prosperous, advanced civilization.
