As a result of the invasion by Drusus and Tiberius and the Roman legions the tract of country then and for some considerable time afterwards known as Rhætia, but now known as Tyrol and the Vorarlberg, ultimately became Romanized, and by the making of the Brenner Post Road, which was constructed by the direction of the Emperor Augustus between Verona and Augsburg (Augusta Vindelicorum), communication between the Germanic Empire and Italy was opened up. Thus was the lowest and most accessible of the passes over the mountains which separated Italy from the barbaric regions beyond crossed by one of those splendid military roads, which has endured nearly two thousand years until the present day.
ROMAN OCCUPATION
The Roman occupation of Rhætia lasted for five centuries. Under the rule of Rome the inhabitants learned much of those arts which remained the heritage of conquered races long after the sway of the great Roman Empire had come to an end. And traces of that rule, in the form of weapons, ornaments, articles of jewelry and the toilet, and other relics have from time to time come to light throughout the portions of Tyrol settled by the Romans.
Soon along the great Brenner Road, which formed a highway from Italy to the northern lands beyond Tyrol, activity evinced itself. One of the most important of the early stations upon it was Veldidena (Wilten), where the road after crossing the main range of mountains emerges from the Alpine gorge on the northern side into a wide and pleasant valley. From this point—close to which, later on, the capital of Tyrol was destined to be founded—the great Brenner Post Road branched. One fork led by two divergent ways to the same objective—Augsburg. The other led in a north-westerly direction by way of Masciacum (Matzen) and Albianum (Kufstein) to Pons Aeni, which in all probability closely approximates to the present-day site of Rosenheim. This road ran down the wide Inn valley, nowadays known as the Unter Innthal to differentiate it from the valley of the Upper Inn which runs from the frontier of Switzerland to Innsbruck.
It was along the great military road leading from Verona to Augsburg that the chief Rhæto-Roman stations were placed. Amongst these were Tridentum (Trent), Pons Drusi (Bozen), Vilpetenum (Sterzing), Matrejum (Matrei), Scarbio (Scharnitz), Veldidena (Wilten).
At first, doubtless, these outposts of Roman civilization were little more than isolated fortresses, or even perhaps merely speculæ or watch towers, and of these many examples still remain, from which not only could the road and its approaches be reconnoitred, but also signals both by day and by night could be made. In the first case by means of smoke or semaphores, and in the second by bonfires kindled in cressets or on the hillside itself.
THE BRENNER PASS
Another highway into Tyrol through the Vintschgau came to be known as the Via Claudia Augusta, which name was also improperly applied to a portion of the Brenner Road. After much contention we think it is now generally accepted that Mommsen, who has investigated and weighed the evidence with astonishing care, is correct in assuming that the only portion of the road via the Reschen-Scheideck Pass which should be called the Via Claudia Augusta is that traversing the Vintschgau Valley. The road was constructed not in the reign of Augustus, who initiated the Brenner Road, but in that of his grandson, the Emperor Claudius, about A.D. 46-47. It was intended to connect up the River Po with the River Danube by the Reschen-Scheideck route, and along it at various times since the middle of the sixteenth century milestones of Roman origin have been discovered. Though from the fact that little reference is made to it by the better-known Roman writers of the period, one may assume that the Via Claudia was of quite secondary importance to the Brenner Road. But nevertheless it seems probable that it was the route used for the transportation of stores for the Roman forces of occupation during the fifth century not long prior to the evacuation of the country. The Brenner Road for a considerable period after its construction appears to have been rather a highway for commerce than a military road in the usual sense of the term.
The chief article exported from Tyrol was salt from the still famous salt mines at Hall, near Innsbruck, on the northern bank of the Inn. There were also sent southward into Italy raw hides, timber, Alpine herbs used in the preparation of medicines, liqueurs, and the purposes of the toilet; and dairy produce of various kinds, of which cheese was probably (according to Pliny) one of the chief articles. In those far-off days, too, much excellent wine was grown far further north in Tyrol than nowadays when the vine is not cultivated, for vintage purposes at all events, further north than the southern slope of the Brenner.
In Roman times the Brenner also formed a link between Aquileia, one of the most flourishing and important seaport cities on the Adriatic, and Noricum. As did also another, then important but nowadays almost deserted route, that of the Plöcken Pass, of which it is believed Cæsar made frequent use. Along this several important stations were founded, amongst them Tricesimum, Julium Carnicum (Zuglio), Aguntum (Innichen), Lonicum (Lienz) and Sebatum (Schabs). Time, however, was destined to divert the trade from the Plöcken Pass route to that of the Brenner, and the settlements along the former gradually declined in importance.
