a gate in the Servian wall, near the Tiber (Fest. 89),
from which fact the name is derived. It was without doubt in that
part of the wall which connected the Capitoline with the river, as the
district known as extra portam Flumentanam was evidently in the
southern part of the campus Martius, and was occupied, at least in part,
by the houses of the wealthy (Liv. vi. 20
; xxxv. 9
and 21; Cic. ad Att.
3. 9; Varro, RR iii. 2
; CIL vi. 9208
; Jord. i. I. 240; Gilb. ii. 299-301
BC 1914, 79
; cf. M61. 1909, 140-141).
