the modern appellation of a nameless postern in the
Aurelian wall immediately to the south of the CASTRA PRAETORIA
which served for the exit of the road from the porta Viminalis of the
Servian wall (see VIA TIBURTINA
). It has a stone curtain with six
windows like those of the porta Latina, and is still in a good state of preservation (Jord. i. I. 355; NS 1899, 403
; PBS iii. 86
, 199, 200).
