“By this title all the toparchs of Edessa were called, just as the Roman emperors were called Cæsars, the kings of Egypt Pharaohs or Ptolemies, the kings of Syria Antiochi.” Assem., Bibl. Or., vol. i. p. 261. Assemani adds: “Abgar in Syriac means lame.” Moses of Chorene, however, with more probability, derives it from the Armenian Avag-aïr, “grand homme, à cause de sa grande mansuétude et de sa sagesse, et de plus, à cause de sa taille.” See below the extract from his History of Armenia, book ii. ch. 26.
