mere incident in history. The Persian Empire of Cyrus, again, which reached from the Hellespont to the Indus, had as high a standard of civilization; and its homelands remained unconquered and fairly prosperous for over two hundred years. Its predecessor, the Median Empire, had endured for half a century. After a brief submergence by Alexander the Great, it rose again as the Seleucid Empire, which endured for some centuries. The Seleucid dominion shrank at last to the west of the Euphrates, and became a part of the Roman Empire; but Persia, revived by the Parthians as a new Persian Empire, first under the Arsacids and then under the Sassanids, outlived the empire of Rome. The Sassanids repeatedly carried war into the Byzantine Empire, and held the line of the Euphrates steadfastly. In 616 A.D. under Chosroes II, they were holding Damascus, Jerusalem, and Egypt, and threatening the Hellespont. But there has been no tradition to keep alive the glories of the Sassanids. The reputation of Rome has flourished through the prosperity of her heirs. The tradition of Rome is greater than its reality.
History distinguishes two chief groups of Roman emperors who were great administrators. The first of these groups began with:—
Augustus Cæsar (27 B.C. to 14 A.D.), the Octavian of the previous section, who worked hard at the reorganization of the provincial governments and at financial reform. He established a certain tradition of lawfulness and honesty in the bureaucracy, and he restrained the more monstrous corruptions and tyrannies by giving the provincial citizen the right to appeal to Cæsar. But he fixed the European boundaries of the empire along the Rhine and Danube, so leaving Germany, which is the necessary backbone of a safe and prosperous Europe, to barbarism; and he made a similar limitation in the east at the Euphrates, leaving Armenia independent, to be a constant bone of contention with the Arsacids and Sassanids. It is doubtful whether he considered that he was fixing the final boundaries of the empire along these lines, or whether he thought it desirable to consolidate for some years before any further attempts at expansion.
Tiberius (14 to 37 A.D.) is also described as a capable ruler, but he became intensely unpopular in Rome, and it would seem that
