elegance, but. the utmoft luxury, Here we firit enter an Apodyterium (QJ,
which was a room for undreffing, and fometimes contained a Callida Pifcina,
or Lukewarm Bath (R), fo large as to allow of fwimming about in it. Next
to this is the Cella Frigidaria (S), in which there was a Babtifterium, or
Cold
Bath. Adjoining to this is the Unduarium (T), or Repofitory for Unguents,
with which the Ancients anointed themselves before their exercises. From
this
we go into the Cella Tepedaria (U), or Cella Media, fo named from its middle
degree of heat, and becaufe it was a neceflary preparation for the. Laconicum,
or Cclla Caidaria (V), which was a bagnio for fweating in. All thefe different
rooms in the Bathing Apartment were lighted from the roof.
  On the other fide of the Cella Media was a Spherifterium (W), a room
alotted for the different exercises of the ball: this too muff have been
lighted
from the roof. On the other fide was the Emperor's Cubiculum Dormitorium,
or Bed Chamber (X), which lay extremely convenient for the Bathing
Apartment, and feems to have been particularly contrived for excluding light
and noife. Pliny mentions an invention of the fame kind in a bed chamber
at
his villa of Laurentinum.
  Adjoining to it, and towards the Crypto Porticus, was what I take to have
been a private Cxnatio (Y), or Supping Room. This enjoyed the benefit of
the fetting fun, which for winter eating rooms Vitruvius recommends as
requifite. On the other fide of the Cubiculum Dormitorium lie three rooms,
two of which, upon the authority of Pliny, I name Procxtones, or Anti-
chambers (Z), and the other Cella Liberti (a), or Freedmans Room.
  Beyond the exterior Procvtori, and adjoining to the Arcade, are a number
of vaults, which were probably employed as Cell, Servorum (b), or Cells for
the Slaves; though originally, and during the time that DIOCLESIAN held
the empire, they might be ufed for lodging the Pretorian Soldiers.
  In thofe Cellx which lie next to the walls of the Bathing Apartments, were
the Hypocaufton (c); the Propnygeon (d); the Milliarium (e) i; and Cella
                                                                 Lignari;
