So much for this. No one can any longer doubt, but it is now clear to all mankind that the Emperor Justinian strengthened the empire, not only with fortifications, but also with garrisons, from the eastern frontier to the setting sun, which are the limits of the Roman dominion. Such of the buildings of Justinian as I have been able to discover, either by having seen them myself, or by hearing them described by those who have seen them, I have as far as I am able described in this work; but I am well aware that I have omitted to speak of many others, which have either escaped my notice by their great number or remain altogether unknown to me; so that anyone who turns his attention to searching them all out and describing them in a book will have the advantage of having performed a useful work, and will gain for himself the reputation of a man of taste. APPENDIX I. Procopius’s description of Justinian’s work at Constantinople is so full and detailed that it would appear to be complete. But it omits one church built by the Emperor, viz., that of the Saviour, to which was attached the Monastery of the Chora, now known as the Mosque Kahireh, or Kahriyeh. The history of this church is thus given in Ducange: ‘Chora seu Χώρα monasterium ita appellatum, condiderat Justinianus et cum præ vetustate concidisset aliud a fundamentis extruxit Alexii Imperatoris socrus Andronici Ducæ conjux. ‘Denique cum ruinam rursum minaretur, illud reædificavit Theodorus Metochita Magnus Logotheta, imperante Andronico Palæologo Seniore. ‘Hæc omnia sic narrat Nicephorus Gregoras, lib. ix.: “Divertit e regione et in vicinia (domus suæ) in sacro scilicet Choræ Monasterio, quod ipse magnis ante sumptibus vetustate ruinosum instauravat. Exstructum enim olim fuerat a Justiniano Imperatore forma oblonga: deinde cum vetustate usque ad ima concidisset, aliud a fundamentis templum, ea qua nunc forma cernitur, Alexii Comneni Imperatoris socrus condidit sed cum rursus ruinam minitaretur, hic medio templo excepto, omnia liberali manu pene instauravit. Metochitam hujus monasterii instauratorem rursus prædicat, lib. viii.”’—Ducange, iv., p. 126. An inscription over the south door of the church states that the monastery was outside the walls of Constantine; that the church was rebuilt by Justinian; again, from its foundations, in the time of Alexis Komnenos; and again rebuilt by Theodore the Metochite.
