receives some support from the existence of a few subterranean
vaults which perhaps go back to the good Greek period. Be that as
it may, the arch plays absolutely no part in the columnar
architecture of Greece. In a Greek temple or similar building only
the flat ceiling was known. Above the exterior portico and the
vestibules of a temple the ceiling was sometimes of stone or
marble, sometimes of wood; in the interior it was always of wood.
It follows that no very wide space could be ceiled over without
extra supports. At Priene in Asia Minor we find a temple (Fig. 49)
whose cella, slightly over thirty feet in breadth, has no interior
columns. The architect of the Temple of Athena on the island of
AEgina (Fig. 52) was less venturesome. Although the cella there is
only 21 1/4 feet in breadth, we find, as in large temples, a
double row of columns to help support the ceiling. And when a
really large room was built, like the Hall of Initiation at
Eleusis or the Assembly Hall of the Arcadians at Megalopolis, such
a forest of pillars was required as must have seriously interfered
with the convenience of congregations. We are now ready to study
the plan of a Greek temple. The essential feature is an enclosed
chamber, commonly called by the Latin name cella, in which stood,
as a rule, the image of the god or goddess to whom the temple was
dedicated. Fig. 47 shows a very simple plan. Here the side walls
of the cella are prolonged in front and terminate in antae (see
below, page 88). Between the antae are two columns. This type of
temple is called a templum in antis. Were the vestibule (pronaos)
repeated at the other end of the building, it would be called an
opisthodomos, and the whole building would be a double templum in
antis. In Fig. 48 the vestibules are formed by rows of columns
extending across the whole width of the cella, whose side walls
are not prolonged. Did a vestibule exist at the front only, the
