And if there are thus distinct historical grounds for the notion of an early Median development, there are not wanting these obscurer but to many minds more satisfactory proofs wherewith comparative philology and ethnology are wont to illustrate and confirm the darker passages of ancient history. Recent linguistic research has clearly traced among the Arba Lisun, or, “Four Tongues” of ancient Chaldaea, which are so often mentioned on the ancient monuments, an Arian formation, such as would naturally have been left in the country, if it had been occupied for some considerable period by a dominant Arian power. The early Chaldaean ideographs have often several distinct values; and when this is the case, one of the powers is almost always an Arian name of the object represented. Words like nir, “man”, ar, “river,” (compare the names Aras, Araxes, Endanus, Rha, Rhodanus, etc., the Slavonic rika, “river,” etc.), san, “sun,” (compare German Sonne, Slavonic solnce, English “sun,” Dutch zon, etc.), are seemingly Arian roots; and the very term “Arian” (Ariya, “noble”) is perhaps contained in the name of a primitive Chaldaean monarch, “Arioch, king of Ellasar.” There is nothing perhaps in these scattered traces of Arian influence in in Lower Mesopotamia at a remote era that points very particularly to the Medes; but at any rate they harmonize with the historical account that has reached us of early Arian power in these parts, and it is important that they should not be ignored when we are engaged in considering the degree of credence that is to be awarded to the account in question.
