together, and formed sixteen, a still more perfect num¬ 
ber. The foot measure gave rise to this, for subtracting 
two palms from the cubit, four remain, which is the 
length of a foot ; and as each palm contains four digits, 
the foot will consequently contain sixteen, so the dena¬ 
rius was made to contain an equal number of asses. If it 
therefore appear, that numbers had their origin from the 
human body, and proportion is the result of a due adjust¬ 
ment of the different parts to each other, and to the 
whole, they are especially to be commended, who, in 
designing temples to the gods, so arrange the parts 
that the whole may harmonize in their proportions and 
symmetry. The principles of temples are distinguished 
by their different forms. First, that known by the appella¬ 
tion IN ANTIS, which the Greeks call vog  i; 
then the PROSTYLOS, PERIPTEROS, PSEUDODIPTEROS, DIPTE¬ 
ROS, HYPATHROS. Their difference is as follows. A tem¬ 
ple is called IN ANTIS, when it has antæ or pilasters in 
front of the walls which enclose the cell, with two columns 
between the antæ, and crowned with a pediment, propor¬ 
tioned as we shall hereafter direct. There is an exam¬ 
ple of this species of temple, in that of the three dedi¬ 
cated to Fortune, near the Porta Collina. The PROSTYLoS 
temple is similar, except that it has columns instead of 
antæ in front, which are placed opposite to antæ at the 
angles of the cell, and support the entablature, which re- 
turns on each side as in those in antis. An example of 
the prostylos exists in the temple of Jupiter and Faunus. 
in the island of the Tyber. The AMPHIPROSTYLOS is si¬ 
milar to the prostylos, but with this addition, that the 
columns and pediment in the front are repeated in the 
rear of the temple. The PERIPTEROS has six columns
