(1) Livy, The Early History of Rome (c. 25 BC)

The dreadful vision was now before their eyes; the towering peaks, the snow-clad pinnacles soaring to the sky... the people with their wild and ragged hair, stiff with frost... There was great confusion and excitement amongst the men, and still more among the terrified horses... the horses were soon out of control... In the confusion many men were flung over the sheer cliffs which bounded each side of the pass, and fell to their deaths thousands of feet below. But it was worst for the pack-animals. Loads and all, they went tumbling over the edge almost like falling masonry.

(2) Livy, The Early History of Rome (c. 25 BC)

The Roman people were not living under a monarchy but were free. They had resolved to throw their gates open to enemies rather than have kings.
