1§ diameter. Then the sum of the diameters of the
columns and intercolumns, with § a diameter for the
two projectures of the angular bases, in an octastyle¿
in systyle intercolumniation, is 22§, and by it, is to
be divided the 220 feet of front, and the quotient is
ft.9 in.Q. 25, the true diameter Of the column in this
temple.

Now if the dimension of the side 425 feet, be conl•-
mensúrate with the front 220, the same method is to be
taken to obtain a divisor, i. e. 15 columns have 16
diameters, 14 intercolumns, at 2 each, equal tó 28
diameters, and projectures § a diameter, the sum of these
is 43|, by which divide 125, the quotient will also be
ft. 9• in.9.24. Thus is seen that the coincidence is per-
fect within an 100th part of an inch : By which is
demonstrated not only the accuracy of Pliny's dimen-
sions of breadth and length of the Temple, but also that
in his given length of 425 feet, there could be no more
nor less, than 15 columns inclusive of the angular co-
lumns at the ends. Nor will there be a coincidence,
between the diameters, by divisions of breadth and
length, in any other species of intercolumns ; and Vi-
truvius teaches that systyle is the species for ionic
columns, and in this Temple the columns were ionic.

The inference I draw from these incontrovertible
premises is, that the foot measure by which Pliny re-
cords the dimensions of this Temple, could not be either
a foot of the size of ours, or of that of the Roman (taken
from the monument of Cossutius,) which is to ours as
967 to 1000 ; because a diameter of column, of ft.9,
in.pj, if of the said Roman feet ft.9, in.5f f of ours, is con-
siderably larger even than that of the surprizing column
near Alexandria, called Pompy*s pillar, whereof the
