The success factor in the Roman military project is closely linked to the fact that they do not have an expensive permanent army. When necessary, the Romans and other subordinate peoples were called upon to participate in some important military onslaught. For the rapid grouping of soldiers to happen, the Roman State had the foresight to build a set of roads that connected the various and distant regions of the empire.

Answer:
The guitar originally had four courses of strings, three double, the top course single, that ran from a violin-like pegbox to a tension bridge glued to the soundboard, or belly; the bridge thus sustained the direct pull of the strings. In the belly was a circular sound hole, often ornamented with a carved wooden rose. The 16th-century guitar was tuned C–F–A–D′, the tuning of the centre four courses of the lute and of the vihuela.
From the 16th to the 19th century several changes occurred in the instrument. A fifth course of strings was added before 1600; by the late 18th century a sixth course was added. Before 1800 the double courses were replaced by single strings tuned E–A–D–G–B–E′, still the standard tuning.
