Upon the ethnic basis here indicated, there was grafted, it would seem, at a very early period, a second, probably Turanian, element, which very importantly affected the character and composition of the people. The _Burbur_ or _Akkad,_ who are found to have been a principal tribe under the early kings, are connected by name, religion, and in some degree by language, with an important people of Armenia, called _Burbur_ and _Urarda,_ the Alarodians (apparently) of Herodotus. It has been conjectured that this race at a very remote date descended upon the plain country, conquering the original Cushite inhabitants, and by degrees blending with them, though the fusion remained incomplete to the time of Abraham. The language of the early inscriptions, though Cushite in its vocabulary, is Turanian in many points of its grammatical structure, as in its use of post-positions, particles, and pronominal suffixes; and it would seem, therefore, scarcely to admit of a doubt that the Cushites of Lower Babylon must in some way or other have become mixed with a Turanian people. The mode and time of the commixture are matters altogether beyond our knowledge. We can only note the fact as indicated by the phenomena, and form, or abstain from forming, as we please, hypotheses with respect to its accompanying circumstances. Besides these two main constituents of the Chaldaean race, there is reason to believe that both a Semitic and an Arian element existed in the early population of the country. The subjects of the early kings are continually designated in the inscriptions by the title of _kiprat-arbat,_ “the four nations,” or _arba lisun,_ “the four tongues.” In Abraham’s time, again, the league of four kings seems correspondent to a fourfold ethnic division, Cushite, Turanian, Semitic, and Arian, the chief authority and ethnic preponderance being with the Cushites. The language also of the early inscriptions is thought to contain traces of Semitic and Arian influence; so that it is at least probable that the “four tongues” intended were not mere local dialects, but distinct languages, the representatives respectively of the four great families of human speech. It would result from this review of the linguistic facts and other ethnic indications, that the Chaldaeans were not a pure, but a very mixed people. Like the Romans in ancient and the English in modern Europe, they were a “colluvio gentium omnium,” a union of various races between which there was marked and violent contrast. It is now generally admitted that such races are among those which play the most distinguished part in the world’s history, and most vitally affect its progress.
