As we have before stated, the Brenner Pass was not originally used so much for military purposes as was afterwards the case. And it is not until the latter half of the second century of the Christian Era that we find it assuming importance as a military highway. Then the frequent incursions southward of various Germanic tribes caused the Romans to fully comprehend the strategical value of northern Rhætia.
Two decades at least were occupied in the reconstruction of the surface and bridges along the road which had owed its origin to the Emperor Augustus, and the result was the building of a highway suitable for the speedy passage and massing of large bodies of troops. Of the stations which were founded along it we have already spoken, it only remains to say that these were supplemented by "posts" which were dotted here and there as they were along most other roads made by Roman builders. They were, however, chiefly used for military and state rather than for ordinary purposes.
An interesting writer,[4] who has made the history of the Brenner a special study, has thrown considerable light upon the inns and hostelries which little by little sprang up to meet the requirements of the travelling public of those days, who were not, as a rule, permitted to make use of the official posts. Apparently, these refuges from the other alternative of spending a night upon the road were by no means luxurious. In fact, they were probably far otherwise, and their chief redeeming feature was the undoubted cheapness of the accommodation they offered. It could not be considered an extravagant charge for a night's lodging with food of sorts when the bill amounted to rather less than the equivalent of an English halfpenny! a sum which would nowadays surprise the modern oste or innkeeper of the Italian Tyrol as much as his own charges would the Roman wayfarer of long ago.
A VILLAGE ON THE BRENNER
ROMAN REMAINS
On the heels of Roman civilization, represented by commerce and travel, which was destined not only to permeate conquered Rhætia, but to penetrate the regions beyond, in course of time there sprang into existence a fortress here and a castle there which not only served to hold the land, but also to encourage and initiate civilization and bring security to those residing in its immediate vicinity. Of these, happily for the historian and antiquarian, many traces yet remain. All along the Brenner the Romans found and were not slow to seize upon natural coigns of vantage where their unexampled skill as military builders and engineers permitted them to speedily convert not easily accessible spurs of the mountains into impregnable fortresses. Upon some of the castles, the ruins of which nowadays serve to render these rocky crags of undying interest, the stars must have looked down ere the dawn of the Christian Era.
Of the occupation of Rhætia by the Romans, unfortunately comparatively few authentic details have come down to us. But long ere the power of Rome had waned, never to reassume its pristine greatness, the problem of resistance to the invasion from the Teutonic tribes to the north and north-east had become a very real one. Towards the end of the third century A.D. the Alemanni crossed the Danube and threatened Rhætia, and through it Italy. They were, it is true, defeated by the Emperor Maximianus, but the check inflicted was but temporary. About A.D. 260 Rhætia was invaded several times by the same barbarian tribe, and on one occasion, at least, Tyrol was ravaged from end to end, and the invaders afterwards entered Italy, which they penetrated as far south as Ravenna, having first plundered and destroyed Verona. In the reign of Claudius (about 269) there was yet another invasion, and although the forces of Rome ultimately proved victorious in the struggle with the Teutonic hordes in a battle fought at Naïssus on the borderland of Tyrol and Italy, when 320,000 are said to have been slain, there was no lasting peace.
The inroads of the Goths vexed many a quickly succeeding Emperor in the days when reigns were scarcely to be reckoned as frequently by years as by months, and it was not until the reign of Aurelianus that the Goths were driven out of Rhætia and Vindelicia.
