Mesopotamia (in 37° 21′ N. lat. and 39° 6′ E. long.) , suggested perhaps by a comparison of its site, or its water supply, [1] with that of its Macedonian namesake. It still bears its earlier name, modified since the 15th century (by the Turks?) to Urfa. The oldest certain form is the Aramaic Urhāi (“Western” pronunciation Urhōi) , which appears in Greek as an adjective as Ὀρροηνή [2] , -νοί [3] (perhaps also as a fortress with spring, as Ὀρρά) , [4] and in Latin as Orr (h) ei, [5] and (in the inscription on Abgar’s grave) Orrhenoru (m) . ”
