From these general indications of an ancient walled town[587] we pass to the more famous sculptures, which are found on the lowest part of the mound towards the south-east, about twenty yards only from the cultivated plain. These decorated the lowest course of the façade of a gateway which in plan resembles closely that of the Lion-gate on the acropolis at Boghaz-Keui. This plan is shown to scale on the opposite page, so that we do not need to give detailed measurements of the blocks where the arrangement involves no reconstruction. Fortunately, though exposed for long ages, the alignment of the stones remains almost intact, so that the plan of this interesting gateway may be determined without much difficulty. It remains also unique hitherto among Hittite works of Asia Minor. As in the Lion-gate at Boghaz-Keui this entrance has an outer and an inner doorway. The nearer one lies back from the frontage of the main wall a distance of just over thirteen feet. The width between the corners of the approach (E, G), making allowance for a slight displacement of the corner-stones, is almost exactly twenty feet: this is reduced between the great monoliths which form the jambs to a few inches over eleven feet. The interval between the faces of the outer and inner monoliths on either side is about twenty-six feet, which must have been approximately the distance from one door to the other. Between the two gateways the space widens out to the same width as the approach outside; but inside the inner gate the walls return at once on either side (II, KK) without any approach on that side corresponding to that from without. Thus the projection of the walls flanking the approach beyond the gates becomes by comparison with the Lion-gate at Boghaz-Keui an established feature of Hittite military architecture, designed to protect the gateway by enfilading fire from above.[588] [Illustration: PLAN OF THE SPHINX-GATE AT EYUK.
