Romana near S. Giorgio in Velabro, and the Porta Mugionis at the Arch of Titus, are still known to us, and the Palatine ring-wall is described by Tacitus from his own observation at least on the sides looking towards the Aventine and Caelian. Many traces indicate that this was the centre and original seat of the urban settlement. On the Palatine was to be found the sacred symbol of that settlement, the "outfit-vault" (-mundus-) as it was called, in which the first settlers deposited a sufficiency of everything necessary for a household and added a clod of their dear native earth. There, too, was situated the building in which all the curies assembled for religious and other purposes, each at its own hearth (-curiae veteres-). There stood the meetinghouse of the "Leapers" (-curia Saliorum-) in which also the sacred shields of Mars were preserved, the sanctuary of the "Wolves" (-Lupercal-), and the dwelling of the priest of Jupiter. On and near this hill the legend of the founding of the city placed the scenes of its leading incidents, and the straw-covered house of Romulus, the shepherd's hut of his foster-father Faustulus, the sacred fig-tree towards which the cradle with the twins had floated, the cornelian cherry-tree that sprang from the shaft of the spear which the founder of the city had hurled from the Aventine over the valley of the Circus into this enclosure, and other such sacred relics were pointed out to the believer. Temples in the proper sense of the term were still at this time unknown, and accordingly the Palatine has nothing of that sort to show belonging to the primitive age. The public assemblies of the community were early transferred to another locality, so that their original site is unknown; only it may be conjectured that the free space round the -mundus-, afterwards called the -area Apollinis-, was the primitive place of assembly for the burgesses and the senate, and the stage erected over the -mundus- itself the primitive seat of justice of the Roman community.
The Seven Mounts
The "festival of the Seven Mounts" (-septimontium-), again, has preserved the memory of the more extended settlement which gradually formed round the Palatine. Suburbs grew up one after another, each protected by its own separate though weaker circumvallation and joined to the original ring-wall of the Palatine, as in fen districts the outer dikes are joined on to the main dike. The "Seven Rings" were, the Palatine itself; the Cermalus, the slope of the Palatine in the direction of the morass that extended between it and the Capitol towards the river (-velabrum-); the Velia, the ridge which connected the Palatine with the Esquiline, but in subsequent times was almost wholly obliterated by the buildings of the empire; the Fagutal, the Oppius, and the Cispius, the three summits of the Esquiline; lastly, the Sucusa, or Subura, a fortress constructed outside of the earthen rampart which protected the new town on the Carinae, in the depression between the Esquiline and the Quirinal beneath S. Pietro in Vincoli. These additions, manifestly the results of a gradual growth, clearly reveal to a certain extent the earliest history of the Palatine Rome, especially when we compare with them the Servian arrangement of districts which was afterwards formed on the basis of this earliest division.
Oldest Settlements in the Palatine and Suburan Regions
The Palatine was the original seat of the Roman community, the oldest and originally the only ring-wall. The urban settlement, however, began at Rome as well as elsewhere not within, but under the protection of, the stronghold; and the oldest settlements with which we are acquainted, and which afterwards formed the first and second regions in the Servian division of the city, lay in a circle round the Palatine. These included the settlement on the declivity of the Cermalus with the "street of the Tuscans"—a name in which there may have been preserved a reminiscence of the commercial intercourse between the Caerites and Romans already perhaps carried on with vigour in the Palatine city—and the settlement on the Velia; both of which subsequently along with the stronghold-hill itself constituted one region in the Servian city. Further, there were the component elements of the subsequent second region—the suburb on the Caelian, which probably embraced only its extreme point above the Colosseum; that on the Carinae, the spur which projects from the Esquiline towards the Palatine; and, lastly, the valley and outwork of the Subura, from which the whole region received its name. These two regions jointly constituted the incipient city; and the Suburan district of it, which extended at the base of the stronghold, nearly from the Arch of Constantine to S. Pietro in Vincoli, and over the valley beneath, appears to have been more considerable and perhaps older than the settlements incorporated by the Servian arrangement in the Palatine district, because in the order of the regions the former takes precedence of the latter. A remarkable memorial of the distinction between these two portions of the city was preserved in one of the oldest sacred customs of the later Rome, the sacrifice of the October horse yearly offered in the -Campus Martius-: down to a late period a struggle took place at this festival for the horse's head between the men of the Subura and those of the Via Sacra, and according as victory lay with the former or with the latter, the head was nailed either to the Mamilian Tower (site unknown) in the Subura, or to the king's palace under the Palatine. It was the two halves of the old city that thus competed with each other on equal terms. At that time, accordingly, the Esquiliae (which name strictly used is exclusive of the Carinae) were in reality what they were called, the "outer buildings" (-exquiliae-, like -inquilinus-, from -colere-) or suburb: this became the third region in the later city division, and it was always held in inferior consideration as compared with the Suburan and Palatine regions. Other neighbouring heights also, such as the Capitol and the Aventine, may probably have been occupied by the community of the Seven Mounts; the "bridge of piles" in particular (-pons sublicius-), thrown over the natural pier of the island in the Tiber, must have existed even then—the pontifical college alone is sufficient evidence of this—and the -tete de pont- on the Etruscan bank, the height of the Janiculum, would not be left unoccupied; but the community had not as yet brought either within the circuit of its fortifications. The regulation which was adhered to as a ritual rule down to the latest times, that the bridge should be composed simply of wood without iron, manifestly shows that in its original practical use it was to be merely a flying bridge, which must be capable of being easily at any time broken off or burnt. We recognize in this circumstance how insecure for a long time and liable to interruption was the command of the passage of the river on the part of the Roman community.
No relation is discoverable between the urban settlements thus gradually formed and the three communities into which from an immemorially early period the Roman commonwealth was in political law divided. As the Ramnes, Tities, and Luceres appear to have been communities originally independent, they must have had their settlements originally apart; but they certainly did not dwell in separate circumvallations on the Seven Hills, and all fictions to this effect in ancient or modern times must be consigned by the intelligent inquirer to the same fate with the charming tale of Tarpeia and the battle of the Palatine. On the contrary each of the three tribes of Ramnes, Tities, and Luceres must have been distributed throughout the two regions of the oldest city, the Subura and Palatine, and the suburban region as well: with this may be connected the fact, that afterwards not only in the Suburan and Palatine, but in each of the regions subsequently added to the city, there were three pairs of Argean chapels. The Palatine city of the Seven Mounts may have had a history of its own; no other tradition of it has survived than simply that of its having once existed. But as the leaves of the forest make room for the new growth of spring, although they fall unseen by human eyes, so has this unknown city of the Seven Mounts made room for the Rome of history.
The Hill-Romans on the Quirinal
But the Palatine city was not the only one that in ancient times existed within the circle afterwards enclosed by the Servian walls; opposite to it, in its immediate vicinity, there lay a second city on the Quirinal. The "old stronghold" (-Capitolium vetus-) with a sanctuary of Jupiter, Juno, and Minerva, and a temple of the goddess of Fidelity in which state treaties were publicly deposited, forms the evident counterpart of the later Capitol with its temple to Jupiter, Juno, and Minerva, and with its shrine of Fides Romana likewise destined as it were for a repository of international law, and furnishes a sure proof that the Quirinal also was once the centre of an independent commonwealth. The same fact may be inferred from the double worship of Mars on the Palatine and the Quirinal; for Mars was the type of the warrior and the oldest chief divinity of the burgess communities of Italy. With this is connected the further circumstance that his ministers, the two primitive colleges of the "Leapers" (-Salii-) and of the "Wolves" (-Luperci-) existed in the later Rome in duplicate: by the side of the Salii of the Palatine there were also Salii of the Quirinal; by the
