The reign of Justinian marked the annihilation of the ancient life in other ways than these. He disbanded the provincial militia, to which we have several times alluded, and which down to his time furnished a guard for the Pass of Thermopylæ. This garrison proved, however, unable to keep out the Huns and Slavs who invaded Greece in 539, and, like the Persians of old, marched through the Pass of Anopaia into the rear of the defenders. The ravages of these barbarians, who devasted Central Greece and penetrated as far as the Isthmus, led Justinian to repair the fortifications of Thermopylæ, where he placed a regular force of 2000 men, maintained out of the revenues of Greece. He also re-fortified the Isthmus, and put such important positions as Larissa, Pharsalos, Corinth, Thebes, and Athens, with the Akropolis, in a state of proper defence. But these military measures involved a large expenditure, which Justinian met by appropriating the municipal funds. The effect of this measure was to deprive the municipal doctors and teachers of their means of livelihood, to stop the municipal grants to theatres and other entertainments, to make the repair of public buildings and the maintenance of roads—the greatest of all needs in a country with the geographical configuration of Greece—most difficult. The old Greek life had centred in the municipality, so that from this blow it never recovered; fortunately, the Church was now sufficiently well organised to take its place, and henceforth that institution became the depository of the national traditions, the mainstay in each successive century of the national existence. Yet another loss to Greece was that of the monuments, which were taken to Constantinople to make good the ravages of the great conflagration, caused by the _Nika_ sedition. The present church of Sta Sophia, which Justinian raised out of the ashes of the second, was adorned with pillars from Athens as well as marble from the Greek quarries, and thus once again, as St Jerome had said, other cities were “stripped naked” to clothe Constantinople. Earthquakes, which shook Patras, Corinth, and Naupaktos to their foundations, completed the destruction of much that was valuable, and the bubonic plague swept over the country, recalling those terrors of which Thucydides and Lucretius had left such a striking description in their accounts of the pestilence at Athens in the days of Perikles. The King of the Ostrogoths, Totila, after twice taking Rome, sent a fleet to harry Corfù and the opposite coast of Epeiros, plundered Nikopolis and the ancient shrine of Dodona. It was in consequence of this and similar raids that the Corfiotes finally abandoned their old city and took refuge in the present citadel, called later on in the tenth century from its twin peaks (Κορυφοί) Corfù, instead of Corcyra. The Bulgarians, a few years later, made a fresh raid as far as Thermopylæ, where they were stopped by the new fortifications.
