Summary

EDESSA, the Greek name of an ancient city of N.W. 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) .

When the Bagdād caliphs lost control of their dominions, Edessa shared the fortunes of western Mesopotamia, changing with the rise and fall of Egyptian dynasties and Arab chieftains. In the 10th century al-Masʽūdī, writing in the very year in which it happened, tells how the Mahommedan ruler of Edessa, with the permission of the caliph, purchased peace of the emperor Romanus Lecapenus by surrendering to him the napkin of Jesus of Nazareth, wherewith he had dried himself after his baptism.

Hadrian, however, abandoning Trajan’s forward policy in favour of a Euphrates boundary, restored it as a dependency of Rome. When L. Verus (163-165) recovered Mesopotamia from Parthia, it was not Edessa but Ḥarrān that was chosen as the site of a Roman colony, and made the metropolis by Marcus Aurelius (172) .
To one of the native kings doubtless is to be ascribed the Syriac inscription [15] on one of the pair of pillars, 50 ft. high, which stood, no doubt, in front of a temple connected with some local cult. Trustworthy data for determining its nature are lacking.
