This passage tacitly implies that at that time a Greek colony had long since held possession of the town, and according to Strabo's testimony (XIII. i. 42), such a colony built Ilium during the dominion of the Lydians. Now, as the commencement of the Lydian dominion dates from the year 797 B.C., and as the Ilians seem to have been completely established there long before the arrival of Xerxes in 480 B.C., we may fairly assume that their first settlement in Troy took place about 700 B.C. Now, there are found no inscriptions later than those belonging to the second century after Christ, and no coins of later date than Constantine II., but very many belonging to Constantine the Great, who, as is well known, intended to build Constantinople on that site, but it remained an uninhabited place till about the end of the reign of Constans II., that is till about A.D. 361. Since the accumulation of _debris_ during this long period of 1061 years amounts only to six and one-half feet, whereas we have still to dig to a depth of forty feet, and in places to forty-six and one-half below this, before reaching the native soil, how many years did it require to form a layer of forty to forty-six and one-half feet? The formation of the uppermost one, the Greek layer of six and one-half feet required 1061. The time required to cover the foundations of Troy to a depth of forty-six and one-half feet of _debris_ must have been very long. The first layer of from thirteen to twenty feet on this hill of Hissarlik belonged to the Aryan race, of whom very little can be said. The second layer was formed by the Trojans of Homer, and are supposed, by Dr. Schliemann and others to have flourished here about 1400 years before Christ. We have only the general supposition of antiquity that the Trojan war occurred about B.C. 1200, and Homer's statement that Dardanus, the first Trojan King, founded Dardania, which town Virgil and Euripides consider identical with Ilium, and that after him it was governed by his son Erichthonius, and then by his grandson Tros, by his great-grandson Ilus, and then by his son Laomedon, and by his grandson Priam. Even if we allow every one of these six kings a long reign of thirty-three years, we nevertheless scarcely carry the foundation of the town beyond 1400 B.C., that is 700 years before the Greek colony.
