PISCINA AQUAE ALEXANDRINAE
a distributing reservoir, probably for
the aqua Alexandrina, situated on the east side of the thermae Helenae,
a little south-west of the porta (Maggiore) Labicana. Remains of at
least twelve compartments of this piscina have been found (HJ 247-248;
LA 387, and pl. viii. 5; LF 32).
