There is nothing Arian in such appellations as Amminapes, Bacasis, Pacorus, Vonones, Sinnaces, Abdus, Abdageses, Gotarzes, Vologeses, Mnasciras, Sanatroeces; nor anything markedly Arian in Priapatius, Himerus, Orodes, Apreetseus, Ornos-pades, Parrhaces, Vasaces, Monesis, Exedares.

If the Parthians were Arians, what account is to be given of these words?
That they employed a certain number of Persian names is sufficiently explained by their subjection during more than two centuries to the Persian rule.

We are also distinctly told that they affected Persian habits, and desired to be looked upon as Persians.
The Arian names borne by Parthians no more show them to be Arians in race than the Norman names adopted so widely by the Welsh show them to be Northmen.

On the other hand, the non-Arian names in the former case are like the non-Norman names in the latter, and equally indicate a second source of nomenclature, in which should be contained the key to the true ethnology of the people.
The non-Arian character of the Parthians is signified, if not proved, by the absence of their name from the Zendavesta.

The Zendavesta enumerates among Arian nations the Bactrians, the Sogdians, the Margians, the Hyrcanians, the Arians of Herat, and the Chorasmians, or all the important nations of these parts except the Parthians.
