A quote
Being trained in a rugged country strengthens the character and fits it for great undertakings. It was more honourable in Scipio to spend his exile at Liternum than at Baiae; his downfall did not need a setting so effeminate. Those also into whose hands the rising fortunes of Rome first transferred the wealth of the state, Gaius Marius, Gnaeus Pompey, and Caesar, did indeed build villas near Baiae; but they set them on the very tops of the mountains. This seemed more soldier-like, to look down from a lofty height upon lands spread far and wide below. Note the situation, position, and type of building which they chose; you will see that they were not country-places,—they were camps.
