[9] Titus Livius I. 44.—Dionysius of Halicarnassus, speaking of the portion of the rampart between the Porta Æsquilina and the Porta Collina, says, “Rome is fortified by a fosse thirty feet deep and a hundred or more wide in the narrowest part. Above this fosse rises a wall supported internally by a lofty and wide terrace, so that it cannot be shaken by battering rams, or overthrown by undermining.” (Antiq. Roman., IX. 68.)
[10] “Since that time (the time of Servius Tullius) Rome has been no farther enlarged ... and if, in face of this spectacle, any one would form a notion of the magnitude of Rome, he would certainly fall into error, for he would not be able to distinguish where the town ends and where it is limited, so close the suburbs come up to the town.... The Aventine, till the reign of Claudius, remained outside the Pomœrium, notwithstanding its numerous inhabitants.” (Aulus Gellius, XIII. 14.—Dionysius of Halicarnassus, IV. 13.)
