Our typical example (Fig. 61) is taken from the Temple of
Priene in Asia Minor--a temple erected about 340-30 B. C. The
column has a base consisting of a plain square PLINTH, two
TROCHILI with moldings, and a TORUS fluted horizontally. The Ionic
shaft is much slenderer than the Doric, the height of the column
(including base and capital) being in different examples from
eight to ten times the lower diameter of the shaft. The diminution
of the shaft is naturally less than in the Doric, and the entasis,
where any has been detected, is exceedingly slight. The flutes,
twenty-four in number, are deeper than in the Doric shaft, being
in fact nearly or quite semicircular, and they are separated from
one another by flat bands or fillets. For the form of the capital
it will be better to refer to Fig. 62, taken from an Attic
building of the latter half of the fifth century. The principal
parts are an OVOLO and a SPIRAL ROLL (the latter name not in
general use). The ovolo has a convex profile, and is sometimes
called a quarter-round; it is enriched with an EGG-AND-DART
ornament The spiral roll may be conceived as a long cushion, whose
ends are rolled under to form the VOLUTES.
