It has already been indicated that the Hittite works in the west are few in number and of somewhat special character, and that they are disposed for the most part seemingly along a single line of road.[358] They betoken a line of conquest rather than a period of settlement. Nevertheless, if we may permit ourselves to take into consideration certain sculptures which, though uninscribed, are of strongly Hittite character, we shall find reason to feel the presence of Hittite influence, or close contact with Hittite artistic feeling, in Galatia north-east from Phrygia. In view of the fact which has been established[359] that the Halys River formed a boundary between peoples of different racial customs, this evidence, if it may be accepted, assumes definite importance, inasmuch as such influence was less likely, under the circumstances, to be the result of neighbourly assimilation. It would argue, in short, for a definite occupation or suzerainty. Of such uninscribed works we may single out three in the immediate vicinity of Angora, the one at Kalaba,[360] which is just eastward of the town, the others at Amaksiz and Yalanjak,[361] which lie to the west and south-west respectively. These are uniform slabs of stone, suitable for the façade of a building, decorated with reliefs of lions.[362] It is not merely the analogy of motive and of subject, but certain details of treatment, which give them a Hittite character. The beasts are in each case represented as advancing, with wide open mouths. The farther legs are advanced and the tail curls over the back. On the lion from Kalaba the body is seemingly hairy below the belly and the collar is suggested. Most characteristic of all is the treatment of the shoulder muscles, which are drawn in conventional outline, as at Eyuk, Sinjerli, and elsewhere. (At Chesme Keupru, also, exposed to the weather on the western side of the bridge, there is a lion sculptured completely in the round. This is in itself a fashion unknown to Hittite art, and added to that there must be noticed the seated posture of the animal and uncouth treatment of the subject. We cannot see in this any semblance of Hittite influence.)
