For several generations after the establishment of the Eastern Empire, Constantinople was the literary capital of the world and the main repository of the arts and sciences. Mr. Middleton has lately shown us in his work upon Illuminated Manuscripts that Persia and Egypt, as well as the Western Countries, 'contributed elements both of design and technical skill which combined to create the new school of Byzantine art.' Constantinople, he tells us, became for several centuries the main centre for the production of manuscripts. Outside the domain of art we find little among the Romans of the East that can in any sense be called original. They were excellent at an epitome or a lexicon, and were very successful as librarians. The treasures of antiquity, as Gibbon has said, were imparted in such extracts and abridgments 'as might amuse the curiosity without oppressing the indolence of the public.' The Patriarch Photius stands out as a literary hero among the commentators and critics of the ninth century. That famous book-collector, in analysing the contents of his library for an absent brother, became the preserver of many of the most valuable classics. As Commander of the Guard he led the life of a peaceful student: as Patriarch of Byzantium his turbulence rent the fabric of Christendom, and he was 'alternately excommunicated and absolved by the synods of the East and West.' We owe the publication of the work called _The Myriad of Books_ to the circumstance that he was appointed to an embassy at Bagdad. His brother wrote to remind him of their pleasant evenings in the library when they explored the writings of the ancients and made an analysis of their contents. Photius was about to embark on a dangerous journey, and he was implored to leave a record of what had been done since his brother had last taken part in the readings. The answer of Photius was the book already mentioned: he reviews nearly three hundred volumes of the historians and orators, the philosophers and theologians, the travellers and the writers of romance, and with an even facility 'abridges their narrative or doctrine and appreciates their style and character.' The great Imperial library which stood by St. Sophia had been destroyed in the reign of Leo the Iconoclast in the preceding age, and in an earlier conflagration more than half a million books are said to have been lost from the basilica. The losses by fire were continual, but were constantly repaired. Leo the Philosopher, who was educated under the care of Photius, and his son and successor Constantine, were renowned as the restorers of learning, and the great writers of antiquity were collected again by their zeal in the square hall near the Public Treasury.
