Note 20 — Chapter III · Legends of the Conversion to Christianity
Reading edition
There is another legend of St. Thaddeus, according to which he converted Abgar and his whole court to Christianity, curing the king of his disease at the same time. (Moses p. 97.) Abgar, who died shortly afterword, divided his kingdom between his son and nephew. The former at once resumed the pagan worship while the latter was forced to apostatize. But the preaching and martyrdom of St. Thaddeus at the hand of Sanatruk, the nephew, is recorded by Faustus of Byzantium, one of the most reliable of early Armenian historians. (Faustus of Byzantium. Langlois 1:210. See also Lynch, Armenia 1:278, and Moses of Khorene pp. 98–99.)
