Our walk through the eastern suburb may be protracted to the slope of Boz Tepe, where an ancient nunnery, famous for its frescos, commands the landscape of the city from a well-chosen site just outside its extreme fringe (No. 6). Adjacent to the building, which presents the appearance of a fortress, was placed the summer residence or pleasure-house whence the Grand-Comneni used to survey their beauteous capital. I can well remember the ruin of this palace, with its blank windows, such a pleasant frame to the charming view which they overlooked. Alas! this fragment has disappeared, to make room for an ugly guest-house which the avaricious nuns have built in its place. The chapel of the nunnery, dedicated to the Virgin, Panagia Theoskepastos, is built into the side of the cliff, its inner end being, in fact, a cave. Damp has blurred the frescos; but one may still recognise the royal portraits upon the north wall. The upper portions of two kingly figures, attired in purple robes, and on their right hand, side by side, two queens with jewelled crowns, still colour the mouldy side of the cave, and are almost hidden by a row of stalls. They have been identified by inscriptions which, I presume, have become effaced, as Alexius III. and his queen Theodora; as Andronicus and Eirene, mother respectively and son of the first-named prince. Nor should the traveller omit a visit to the church of St. Eugenius (No. 19), although he may not have time to visit the grottoes in the face of Boz Tepe, and to protract the excursion beyond the embouchure of the Pyxitis to the site of Xenophon's camp. That famous church is situated in the opposite direction, and has been already mentioned in the description of the upper fortress. It stands on the margin of the eastern ravine, almost opposite to the great polygonal tower. The site is separated from the slopes of Boz Tepe by a second and smaller ravine, which shows remains, on the western bank, of walls and towers. Houses cluster round the building, their horizontal outlines topped by its gables and crowned by its polygonal, drum-shaped dome. St. Eugenius dates from the period of the Grand-Comneni; but the frescos on the western wall, which some travellers have noticed, are now nothing more than patches of colour. It is a somewhat larger edifice than Hagia Sophia, which, although less graceful, it resembles in some respects. The dome rests upon two fluted columns on the west side, while, on the east, it is supported by piers. A flood of light fills the interior, which is plain and bare, the church having been converted to the service of Islam by the Ottoman conqueror. It was here that Mohammed II. is said to have worshipped on the first Friday after the capture of the city by his troops. The event is commemorated by the name of New Friday
