These fourteen regions do not correspond in position, name, or extent with those of Augustus except that the present thirteenth, Trastevere, is identical with the ancient fourteenth, Transtiburtina. The names that they bear to-day represent either their position or some characteristic feature within their limits. Thus the first and largest region, the _Monti_, formed from the union of the fifth and sixth of Augustus, the _Esquilina_ and the _Alta Semita_, is so called from the hills, the Esquilina Viminal and Caelian, within its boundaries; the second the _Trevi_, derives its name from the famous fountain in its midst; the third, _Colonna_, from the column of Marcus Aurelius; the fourth, _Campo Marzo_, covers this historic ground; the fifth, _Ponte_, is named from the old _Pons Triumphalis_, that united Rome with the Vatican region; the sixth or _Parione_ comprises the ground of which the Chiesa Nuova is the centre, and the name was derived from the ancient wall and tower which stood close to it; the seventh, _Regola_, inhabited by some of the most wretched of the population, is a corruption of Arenula, the drift sand of the river near which this region lies; the eighth, _S. Eustachio_, behind the university, takes its name from a parish church; the ninth, _Pigna_, from the bronze pine cone now at the Vatican and which was once supposed to adorn the Pantheon (this region corresponds to a certain extent with the ancient Via Lata); the tenth region, _Campitelli_, includes the Capitol and Palatine hills and the Forum; the eleventh, the _S. Angelo_ district, a region inhabited by the very poor, by tanners, and formerly the Jews' quarter, is named after the church of S. Angelo in Pescheria; the twelfth is the _Ripa_ or river bank; and the thirteenth and fourteenth, as we have seen, are _Trastevere_ beyond the river and the Leonine city or _Borgo_. [Illustration: FOUNTAIN OF TREVI One of the numberless fountains of the city; built by Clement XII. in 1735. The red house is the _palazzo_ of the celebrated art jeweller Castellani. Visitors leaving Rome who throw a _sou_ into this fountain are sure to return to the eternal city. See pages 22, 55, 227.] Each region became a little civic and social centre complete in itself. Each had its captain, its sub-officers, its religious organisations, its separate funds for charities and dowries, its separate police and militia recruits. And the importance that accrued to these regions lay in the fact that they represented the _plebs_, the democracy of Rome. With a people so incapable of co-operation for a common end as the Roman, the spark of their civic liberties would have been trodden out or have remained for ever dormant but for this administrative setting which kept it alive and through which, given the opportunity, it could become once more a living force.
