.&#8212;How the Armenians and Persians embraced Christianity.

the Christian religion became known to the neighboring tribes and was very greatly disseminated.

The Armenians, I have understood, were the first to embrace Christianity.

It is said that Tiridates, then the sovereign of that nation, became a Christian by means of a marvelous Divine sign which was wrought in his own house; and that he issued commands to all the subjects, by a herald, to adopt the same religion.

I think that the beginning of the conversion of the Persians

was owing to their intercourse with the Osroenians and Armenians; for it is likely that they would converse with such Divine men and make experience of their virtue.
