He travelled into Spain and France, and finally returned to Padua, and at Sacco on the 30th of October 1576 his youngest son, Enrico Caterino, was born.
South of Palestrina again, the main mass of the Apennines throws off another lateral mass, known in ancient times as the Volscian mountains (now called the Monti Lepini), separated from the central ranges by the broad valley of the Sacco, a tributary of the Liri (Liris) or Garigliano, and forming a large and rugged mountain mass, nearly 5000 ft.
The new port works, under construction since 1903, consist of a new water-front for the Saude, Gamboa and Sacco de Alferes districts, in which the shipping interests are centred, and a continuation of the sea-wall across the shallow Sao Christovao bay to the Ponta do Caju, the large reclaimed area to be filled in by the removal of some small hills.
Several of the Latin cities, including Tibur and Praeneste, were situated on the terrace-like underfalls of these mountains, 2 while Cora, Norba and Setia were placed in like manner on the slopes of the Volscian mountains (Monti Lepini), a rugged and lofty limestone range, which runs parallel to the main mass of the Apennines, being separated from them, however, by the valley of the Trerus (Sacco), and forms a continuous barrier from there to Terra.cina.
In 299 B.C. further successes led to the establishment of two new tribes - the Teretina in the upper valley of the Trerus (Sacco) and the Aniensis, in the upper valley of the Anio - while to about the same time we must attribute the construction of two new military roads, both secured by fortresses.
