ANCIENT ARCHITECTURE. 61

There are also round temples, of which
some are Mpnopteral, without cells, and
built on columns: the other is called Pe-
ripteral. Those without cells have a tri-
bunal or throne, and are ascended by steps
of one third of the diameter of the temple:
the columns, placed on pedestals, are as
high as the diameter of the temple, taken
at the outer side of the pedestals; their
thickness is one tenth part of the height of
the shaft and capital: the height of the
architrave is half the diameter of the co-
lumn: the frize, and other ornaments
above, may be according to the general
rule.

The Peripteral is built with an ascent of
two steps, on which the pedestals of the
columns are placed: the wall of the cell is
distant one fifth part of the diameter of
the temple from the pedestals of the co-
lumns: in the middle is left a space for
folding doors: the diameter of the inner
part of the cell must be equal to the height
of a column without the pedestal; the cor
lumns round the cell are placed with suit-
able proportion and symmetry. The en-
closure in the middle is thus proportioned;
