In the early Roman period, the northern limit of Roman territory extended to the Po, and no farther. Beyond was Cisalpeà, and so it continued until Augustus Cæsar Imperator finally subdued, some thirty years before the birth of Christ, the whole of the warlike tribes, and brought them under Roman subjection. History records but one solitary instance of the vanquished erecting a monument to do honour to their conqueror. This was at Susa, and the inscription on the PORTA CÆSARIS AUGUSTI tells us why it was erected, and what deed it was intended to perpetuate.
Hannibal’s was the first army that made a passage across the Alps, but the exact part at which he effected it is still matter of historic doubt. The balance of worthful opinion is however strongly in favour of its being by what we now call the Pass of the Little St. Bernard. The army would appear not to have been subjected to great difficulties in reaching its summit, notwithstanding that the 19th of October is believed to be the day on which the ascent was commenced, but the horrors to which his hourly thinned ranks were exposed, all occurred after they had attained the summit, and were within sight of the plains in which the autumnal foliage still spread a rich and glowing landscape before them. That some few of the army of ninety elephants with which Hannibal started from Spain completed the Alpine traverse is more than probable, but that one accomplished it is undoubted, for we have it on record that the Carthaginian General crossed the marshes of Clusium (which will be traversed by the railway train of the new and comparatively shorter line between Florence and Rome, to be opened for traffic a few months hence) upon the only elephant that was still spared to him.
Brockedon, whose illustrated work on Alpine Passes was published in 1828, states that there were ten passes traversable as carriage roads. The actual number has not been added to since then, but the trackway along many of the other passes has been greatly improved, and many, that at that period were only dangerous and very narrow mule paths, have now become available for _chars_, and possess other facilities and accommodation for traversing them that were quite unknown forty years ago. A very brief recapitulation of them may not be inappropriate. More full details of them can be obtained in _The Alps and the Eastern Mails_, a little work which we published a few months ago.
