temple would be called prostyle; as it is, it is amphiprostyle.
Only small Greek temples have as simple a plan as those just
described. Larger temples are peripteral, i.e., are surrounded by
a colonnade or peristyle (Figs. 49. 50). In Fig. 49 the cella with
its vestibules has the form of a double templum in antis, in Fig
50 it is amphiprostyle. A further difference should be noted. In
Fig. 49, which is the plan of an Ionic temple, the antae and
columns of the vestibules are in line with columns of the outer
row, at both the ends and the sides; in Fig. 50, which is the plan
of a Doric temple, the exterior columns are set without regard to
the cella wall, and the columns of the vestibules. This is a
regular difference between Doric and Ionic temples, though the
rule is subject to a few exceptions in the case of the former.

The plan of almost any Greek temple will be found to be referable
to one or other of the types just described, although there are
great differences in the proportions of the several parts. It
remains only to add that in almost every case the principal front
was toward the east or nearly so. When Greek temples were
converted into Christian churches, as often happened, it was
necessary, in order to conform to the Christian ritual, to reverse
this arrangement and to place the principal entrance at the
western end.

The next thing is to study the principal elements of a Greek
temple as seen in elevation. This brings us to the subject of the
Greek "orders." There are two principal orders in Greek
architecture, the Doric and the Ionic. Figs. 51 and 61 show a
characteristic specimen of each. The term "order," it should be
said, is commonly restricted in architectural parlance to the
