We have no reason to doubt that Eusebius, who is the first to mention these apocryphal epistles, really found them in the public archives at Edessa. Moses Chorenensis, the celebrated Armenian historian of the fifth century, who studied a long time in Edessa, is an independent witness to their existence in the Edessene archives. Eusebius has been accused of forging this correspondence himself; but this unworthy suspicion has been refuted by the discovery and publication of the original Syriac (The Doct. of Addai the Apostle, with an English Translation and Notes, by G. Phillips, London, 1876; compare also Contemp. Rev., May, 1877, p. 1137). The epistles were forged probably long before his day, and were supposed by him to be genuine. His critical insight, but not his honesty, was at fault. The apocryphal character of these letters is no longer a matter of dispute, though Cave and Grabe defended their genuineness (so that Eusebius is in good company), and even in the present century Rinck (Ueber die Echtheit des Briefwechsels des Königs Abgars mit Jesu, Zeitschrift für Hist. Theol., 1843, II. p. 326) has had the hardihood to enter the lists in their defense; but we know of no one else who values his critical reputation so little as to venture upon the task.
