The Palatine had been settled by the earliest Romans, the Sabines had occupied the Capitoline hill with the Citadel, on one side of the Palatine, and the Albans the Caelian hill, on the other, so the Aventine was assigned to the new-comers.
Not long afterwards there was a further addition to the number of citizens through the capture of Tellenae and Ficana. Politorium after its evacuation was seized by the Latins and was again recovered; and this was the reason why the Romans razed the city, to prevent its being a perpetual refuge for the enemy.
