SEPTIMIANUM
probably a name which came to be given to the district
lying along the right bank of the Tiber, from the Aurelian wall to the
Vaticanum, on account of the building activity of Septimius Severus
in part of this quarter (cf.
PORTA SEPTIMIANA). This name does not
occur in any ancient sources (unless we accept the reading Septimianae
in Hist. Aug. Sev. 19; cf.
THERMAE SEPTIMIANAE), but is to be inferred
from its use in the Middle Ages, reappearing in the designations of
churches, as S. Iacobi in Septimiano
(1286), S. Leonardi de Sitignano,
S. Lucia de Septignano (Arm. 653, 656;
Mel. 1914, 351-352; HJ 656;
HCh 268, 299, 305); cf.
CORARIA SEPTIMIANA.
