The Israel Antiquities Authority just released pictures of marvelous mosaics found in an industrial park in Qiryat Gat, Israel – they once graced the floor of a church likely built in Justinian’s lifetime, featuring christian and more traditional (pagan) images.  Curiously, the mosaics also depicted a map of an Egyptian city – Chortaso – which might have been the original home of this congregation though the true meaning of the map is a mystery.

Why would a church in Judaea have a map of a town in Egypt gracing its floor?
