 The hill is described by Dionysius of Halicarnassus as "ὑψηλὸν ἐπιεικῶς καὶ περίτομον" (high and steep).A primitive grave found in 1908 near the Arch of Titus lay at about 28 metres above sea-level, whereas virgin soil was found in the lowest part of the valley occupied by the Roman Forum at 3.6m, and in connection with the excavation of the Sepulcretum, at 10.63 metres.The original height of the ridge may have been somewhat diminished by the construction of the Domus Aurea.
