The most detailed description that survives about Roman military camps is De Munitionibus Castrorum, a manuscript of 11 pages that dates most probably from the late 1st to early 2nd century AD.[7] From the most ancient times Roman camps were constructed according to a certain ideal pattern, formally described in two main sources, the De Munitionibus Castrorum and the works of Polybius.[15] P. The street plans of various present-day cities still retain traces of a Roman camp, for example Marsala in Sicily, the ancient Lilybaeum, where the name of the main street, the Cassaro, perpetuates the name "castrum". Castle has the same derivation, from the diminutive castellum or "little fort", but does not usually indicate a former Roman camp. ./cache/en-wikipedia-org-9441.html ./txt/en-wikipedia-org-9441.txt
