] Finally,
attention may be called to the ASTRAGAL or PEARL-BEADING just
under the ovolo in Figs. 61, 71. This might be described as a
string of beads and buttons, two buttons alternating with a single
bead.
In the normal Ionic capital the opposite faces are of identical
appearance. If this were the case with the capital at the corner
of a building, the result would be that on the side of the
building all the capitals would present their bolsters instead of
their volutes to the spectator. The only way to prevent this was
to distort the corner capital into the form shown by Fig. 64; cf.
also Figs. 61 and 70.
The Ionic architrave is divided horizontally into three (or
sometimes two) bands, each of the upper ones projecting slightly
over the one below it. It is crowned by a sort of cornice enriched
with moldings. The frieze is not divided like the Doric frieze,
but presents an uninterrupted surface. It may be either plain or
covered with relief-sculpture. It is finished off with moldings
along the upper edge.
