Hereabouts, in the dip between the two forts last described, is the weathered rock inscription known as Nishan Tash.[486] Descending thence to the lower ground, following the course of the stream which flows through the middle of the enclosure, two further rocks arrest attention by the fact that they have been worked by hand. The first of these is called the Maiden’s Rock, and has given its Turkish name of Kizlar Kaya to the stream which passes just below it. Though of considerable dimensions, this rock, besides being dressed around the sides and worked down squarely in two places in the body, has been cleanly cut across the top with the exception of a small table-like protuberance remaining towards one end. The other, which lies still further down and nearer to the Lower Palace, has been cleft in two, to form as it were a passage through it from side to side. It would be unsafe without evidence to suggest any definite use for these rocks in ancient times, and it is possible that their peculiarities may have resulted only from the quarrying of the stone blocks used for the Lower Palace or other buildings of the site. [Illustration: PLATE LXI BOGHAZ-KEUI: THE FORTRESS CALLED YENIJE-KALEH (_See p. 205._) BOGHAZ-KEUI: REMAINS OF THE LOWER PALACE] We use the term Lower Palace to designate the foundations made famous by the visit of Texier,[487] and the later descriptions of Professor Perrot,[488] in distinction to those more recently discovered by Dr. Winckler on the Upper Acropolis, where the ruins of four such buildings were found, of which three were probably palaces and the fourth a temple.[489] The lower courses of the first-mentioned palace, however, are visible above the ground, so that its plan may be readily traced out; and whether to be identified as palace or as a temple, it presents an interesting study, and a peculiar link between the architecture of the East and West.[490] As may be seen in our photograph,[491] that which remains of it is built in large single blocks of stone about four feet in thickness and averaging twice that measure in length. Its form is rectangular, with a length just over two hundred and ten feet down the main axis, and a width of one hundred and twenty-eight feet. Its chief entrance is in the middle of the southern side, and, passing small guard-rooms on either hand, it leads into a large central court, around which are chambers, a double series at the ends and a single series at the sides. To the north and to the west a passage or corridor intervenes between the court and the rooms: that on the north seems to have been entered by an opening opposite the main entrance, and one chamber (across the passage and to the left) is filled by a large tank or bath of stone. These portions of the building may be judged to have been residential, while the front and east wings were devoted to offices of the palace. There are few further features of the interior obvious to the eye except
