Pomerium

But to return to the point from which I digressed, and to illustrate how some people spend useless efforts on these same topics, the man I referred to reported that Metellus in his triumph, after conquering the Carthaginians in Sicily, alone among all the Romans had 120 elephants led before his chariot, and that Sulla was the last of the Romans to have extended the pomerium, [footnote: The religious boundary of a city.] which it was the ancient practice to extend after acquiring Italian, but never provincial territory. Is it better to know this than to know that the Aventine Hill, as he asserted, is outside the pomerium for one of two reasons, either because the plebs withdrew to it or because when Remus took the auspices there the birds had not been favourable – and countless further theories that are either false or very close to lies?

Nay Sidonius Apollinaris aſſures us farther, that the Place where St. Peter was buried, tho' there was then a Church built over it, was ſtill in his Time, An. 470. without the Pomœria, or Space before the Walls of Rome. For ſpeaking of his Journey to Rome, he ſays, before ever he came at the Pomœria of the City, he went and ſaluted the Church of the Apoſtles, which ſtood in the Via Triumphalis.

The myth [of Romulus and Remus] insisted on the exclusion of the Aventine from the boundary of the pomerium, emphasizing that it was a place apart from Rome proper, even if closely related to the city's sacred enclosure. And at the end of this episode, the killing of Remus underlined the sanctity of the city's boundary, dearer than any brother. The myth presents a definition of Rome. The pomerium had a physical presence too. In the imperial period it was clearly marked by massive blocks of stone, 2 m. tall and 1 m. square.
