in Ancient Geography, one of the seven hills of Rome, which Varro will have to be two, viz. Cispia and Oppius; also Mons Esquilinus, softened from Exquillius; and this again from Excaubius, the watch or guard Romulus kept here, from a jealousy he entertained of his colleague Titus Tatius. On the east side it reached the city walls; on the south, the Via Liviana; on the west, the wide valley between Mount Coelius and the Palatine; on the north, the Mons Viminalis; on the east side was the Porta Esquilina. This hill by some of the ancients was called Suburranus, from the street Suburra to the north of it: by the poets, Esquilinus.
