Doubtless some clear evidence will be forthcoming with the progress of excavations; for the present we can only pay due regard to the few items of circumstantial evidence that are available. The absence of visible sculptures on the façade of the building, in contrast with the buildings of Eyuk, Sinjerli, and Sakje-Geuzi, is curiously significant. That phase of motive seems to be reflected rather in the two sculptured stones already mentioned as recently found somewhat further up the slope of Beuyuk Kaleh, at the foot of which the palace stands.[497] Two sculptured lions indeed are found lying in close proximity to the lower palace, those which were supposed by Texier and Perrot[498] to be the arms of a throne, but are now shown[499] to be the end ornaments of a tank, with a similar pair on the opposite side. These correspond both in style and in details of art with the lions guarding the palace entrance at Sakje-Geuzi,[500] which may be dated with some security to the tenth or ninth century B.C. If then the lions of Boghaz-Keui can be shown to have organic relation to the palace in the precincts of which they lie, then a basis for solution to the problem is obtained, and the date depends upon the range of time during which such sculptures were in vogue. But if, on the other hand, this tank was an addition to the palace, and of later date, as its partly exposed situation, above the level of the palace floor, suggests, then the palace is of earlier date, preceding the period when such sculptured lions were in fashion, a conclusion which our other considerations seem to justify. Incidentally we arrive at a possible date for certain sculptures of like kind, as the lion of Eyuk, and possibly the Lion Gateway of the acropolis.

Period of the earlier lower palace. 1300-1200 ” Main fortifications built, _temp._ Hattusil. 1200-1100 ” First Phrygian invasions. 1100-1000 ” Lower palace reconstructed. 1000-850 ” Period of Lion-sculptures. 850-700 ” Phrygian domination. 700-600 ” Cimmerians. _Circa_ 550 ” Fall before Crœsus.
