Though very far from being as full as could be wished, the accounts of libraries in Rome are more numerous than any relating to libraries in other parts of the ancient world. Besides the collections of books made by private persons, which in one or two instances were generously opened to the public by the owner, there were the imperial libraries, and the more strictly public libraries. Among the emperors whose names are especially associated with the gathering and preservation of books are Augustus, Tiberius and Trajan. Julius Cæsar had formed a scheme for the establishment of a public library, but it is not clear whether it was ever carried out or no. Domitian, to replace the library in the Capitol, which had been destroyed, sent scholars abroad to collect manuscripts and to copy some of those at Alexandria. Under Constantine the Roman public libraries numbered twenty-nine, and were very frequently lodged in the temples. Last in point of date come the libraries of Byzantium, the city which the Emperor Constantine in 330 A.D. made the capital of the eastern portion of the empire, and named after himself. He at once began to gather books there, and his successors followed his example. Thus various libraries were established, and those which survived the fires which occurred from time to time in the city, existed until its capture by the Turks in 1452. On this occasion, and also after the assault by the Crusaders in 1203, the libraries probably suffered. It is said, too, by some that Leo III. wantonly destroyed a large number of books, but the assertion cannot be proved. Among the lost treasures of Constantinople was "the only authentic copy" of the proceedings of the Council of Nice, held in 325 A.D. to deal with the Arian heresy.
