Douglas over a the Scrivener has recently posted an article about Orthodox Missions to Muslims. His mention of the conversion of the Al-Khattab tribe spurred a memory of some recent scholarly work done on a couple of nomadic Christian tribes that settled in Jordan's Karak Plateau in the ancient village of Simakiyya about the turn of the century. One tribe is Greek Melkite, the other adheres to the Latin Patriarchate (both in communion with Rome).
Great pictures on the site.
