Their congeners in Western Asia were the early Babylonians and the Susianians, not the Medes, the Persians, or the Phrygians.

But by the time of Herodotus the Arian character of the Armenians had become established.

Their close connection with the Phrygians was recognized.
They had changed their national appellation; for while in the Assyrian period the terms Nairi and Urarda had preponderated, under the Persians they had come to be called Armenians and their country Armenia.

The personal names of individuals in the country, both men and women, had acquired a decidedly Arian cast.

Everything seems to indicate that a strange people had immigrated into the land, bringing with them a new language, new manners and customs, and a new religious system.
