PINCIUS MONS
a hill divided from the Quirinal by the valley occupied
by the Horti Sallustiani, running in a westerly direction from the Porta
Salaria of the Aurelian Wall, and then north-north-west from the Porta
Pinciana to the Muro Torto and then west again to the Porta Flaminia.
It thus formed the east part of the
seventh region. It was known in the
early imperial period as Collis Hortulorum (Suet. Nero, 50; in Hist.
Aug.
Gord. iii. 32 it is simply called collis-'
in campo Martio sub colle')
and the post-classical name Mons Pincius comes from its owners in the
fourth century A.D.: see
DOMUS PINCIANA,
HORTI ACILIORUM,
HORTI
LUCULL(I)ANI. The substructions of the last-named altered the contour
of the hill considerably, and were made use of by Aurelian, who included
them in his hastily erected enceinte. See HJ 444-450.
