Centuries elapsed before men understood that Alexander had not merely erected an ephemeral kingdom in the east, but had carried Hellenism to Asia; centuries again elapsed before men understood that Caesar had not merely conquered a new province for the Romans, but had laid the foundation for the Romanizing of the regions of the west. It was only a late posterity that perceived the meaning of those expeditions to England and Germany, so inconsiderate in a military point of view, and so barren of immediate result. An immense circle of peoples, whose existence and condition hitherto were known barely through the reports--mingling some truth with much fiction--of the mariner and the trader, was disclosed by this means to the Greek and Roman world. "Daily," it is said in a Roman writing of May 698, "the letters and messages from Gaul are announcing names of peoples, cantons, and regions hitherto unknown to us." This enlargement of the historical horizon by the expeditions of Caesar beyond the Alps was as significant an event in the world's history as the exploring of America by European bands. To the narrow circle of the Mediterranean states were added the peoples of central and northern Europe, the dwellers on the Baltic and North seas; to the old world was added a new one, which thenceforth was influenced by the old and influenced it in turn. What the Gothic Theodoric afterwards succeeded in, came very near to being already carried out by Ariovistus. Had it so happened, our civilization would have hardly stood in any more intimate relation to the Romano-Greek than to the Indian and Assyrian culture. That there is a bridge connecting the past glory of Hellas and Rome with the prouder fabric of modern history; that Western Europe is Romanic, and Germanic Europe classic; that the names of Themistocles and Scipio have to us a very different sound from those of Asoka and Salmanassar; that Homer and Sophocles are not merely like the Vedas and Kalidasa attractive to the literary botanist, but bloom for us in our own garden--all this is the work of Caesar; and, while the creation of his great predecessor in the east has been almost wholly reduced to ruin by the tempests of the Middle Ages, the structure of Caesar has outlasted those thousands of years which have changed religion and polity for the human race and even shifted for it the centre of civilization itself, and it stands erect for what we may designate as eternity.
The Countries On The Danube
To complete the sketch of the relations of Rome to the peoples of the north at this period, it remains that we cast a glance at the countries which stretch to the north of the Italian and Greek peninsulas, from the sources of the Rhine to the Black Sea. It is true that the torch of history does not illumine the mighty stir and turmoil of peoples which probably prevailed at that time there, and the solitary gleams of light that fall on this region are, like a faint glimmer amidst deep darkness, more fitted to bewilder than to enlighten. But it is the duty of the historian to indicate also the gaps in the record of the history of nations; he may not deem it beneath him to mention, by the side of Caesar's magnificent system of defence, the paltry arrangements by which the generals of the senate professed to protect on this side the frontier of the empire.
Alpine Peoples
North-eastern Italy was still as before(56) left exposed to the attacks of the Alpine tribes. The strong Roman army encamped at Aquileia in 695, and the triumph of the governor of Cisalpine Gaul Lucius Afranius, lead us to infer, that about this time an expedition to the Alps took place, and it may have been in consequence of this that we find the Romans soon afterwards in closer connection with a king of the Noricans. But that even subsequently Italy was not at all secure on this side, is shown by the sudden assault of the Alpine barbarians on the flourishing town of Tergeste in 702, when the Transalpine insurrection had compelled Caesar to divest upper Italy wholly of troops.
Illyria
The turbulent peoples also, who had possession of the district along the Illyrian coast, gave their Roman masters constant employment. The Dalmatians, even at an earlier period the most considerable people of this region, enlarged their power so much by admitting their neighbours into their union, that the number of their townships rose from twenty to eighty. When they refused to give up once more the town of Promona (not far from the river Kerka), which they had wrested from the Liburnians, Caesar after the battle of Pharsalia gave orders to march against them; but the Romans were in the first instance worsted, and in consequence of this Dalmatia became for some time a rendezvous of the party hostile to Caesar, and the inhabitants in concert with the Pompeians and with the pirates offered an energetic resistance to the generals of Caesar both by land and by water.
Macedonia
Lastly Macedonia along with Epirus and Hellas lay in greater desolation and decay than almost any other part of the Roman empire. Dyrrhachium, Thessalonica, and Byzantium had still some trade and commerce; Athens attracted travellers and students by its name and its philosophical school; but on the whole there lay over the formerly populous little towns of Hellas, and her seaports once swarming with men, the calm of the grave. But if the Greeks stirred not, the inhabitants of the hardly accessible Macedonian mountains on the other hand continued after the old fashion their predatory raids and feuds; for instance about 697-698 Agraeans and Dolopians overran the Aetolian towns, and in 700 the Pirustae dwelling in the valleys of the Drin overran southern Illyria. The neighbouring peoples did likewise. The Dardani on the northern frontier as well as the Thracians in the east had no doubt been humbled by the Romans in the eight years' conflicts from 676 to 683; the most powerful of the Thracian princes, Cotys, the ruler of the old Odrysian kingdom, was thenceforth numbered among the client kings of Rome.
