The only difficulty in the way of this theory was the supposed Medo-Persic or Arian character of a certain number of Assyrian royal names; but this difficulty was thought to be sufficiently met by a suggestion that the ruling tribe might have been of Median descent, and have maintained its own national appellatives, while the mass of the population belonged to a different race.

Recent discoveries have shown that this last suggestion was needless, as the difficulty which it was intended to meet does not exist.

The Assyrian names which either _history_ or the monuments have handed down to us are Semitic, and not Arian.

It is only among the fabulous accounts of the Assyrian Empire put forth by Ctesias that Arian names, such as Xerxes, Arius, Armamithres, Mithraus, etc., are to be found.
Together with the true names of the Assyrian kings, the mounds of Mesopotamia have yielded up a mass of documents in the Assyrian language, from which it is possible that we may one day acquire as full a knowledge of its structure and vocabulary as we possess at present of Greek or Latin.

These documents have confirmed the previous belief that the tongue is Semitic.
