90 ANCIENT EPHESUS.
stylium of two stadia, of Vitruvius; which identity
of measurement is quite sufficient to fully establish
the name and position of this portion of Vitruvius'
description.1 But this difference is to be observed :
that Vitruvius says that the diaulas is open, on
which account the portico on the south side is to
be double, in order to protect it from the weather;
whereas in the example before us the diaulus is
closed in on three sides, and open in front. This
arises, however, from the circumstance of these
gymnasia being urban ones, and, from want of
space, deprived of the advantage of a surrounding
area, on which account it became necessary to pro-
tect the diaulus from the inconvenience derived from
juxtaposition to the adjacent buildings. It is satis-
factory also to find that in each of these examples
the front of the crypto-porticus, or diaulus, is placed
next the south, agreeably to the description of
Vitruvius ; and that exedrge are contrived in the thick-
ness of the wall, throughout their whole length, for
the philosophers and others to resort to. Vitruvius
next describes the front of the building, which
consists of seven rooms, the ephebium being in the
centre, the conisterium, coryceum, and loutron on
the right, and the elreothesium, tepidarium, and pro-
pnigeum or prasfurnium on the left. This disposition
' The gymnasium at Alexandria Troas is too ruined to measure
with certainty the circuit of the crypto-porticus ; but if the sides
bore a similar proportion to the end, as in those of Ephesus, the
circuit would rather exceed the measure of two stadia.
