PLATE IV. 
PLAN OF AN HYPAETHRAL TEMPLE. 
The proportions of the temple represented in this plate 
are similar to those which may be collected from Pliny's 
account of the temple of Diana at Ephesus. According 
to this author, lonic bases and capitals were first introduced 
in the columns of that temple. 
PLATE V. 
Fig. 1. Explanation of the mode in which the addition 
was made in the middle of the stylobate of a temple. 
Although our author assigns no reason why a stylobate 
constructed upon a horizontal level would appear hollow. 
like the bed of a channel, yet it is evident that he thought 
an addition in the middle necessary to counteract some 
supposed imperfection of vision. A stylobate thus constructed 
would not permit the axes of columns placed upon it to be 
vertical, unless small plinths, higher at one end than the other, 
were first placed below the plinths of the bases; or the plinths 
themselves were made like wedges; the height gradually 
diminishing from one end to the other, so that their upper 
surfaces might be in horizontal planes. The line of the 
capitals of the columns ought not, we are told, to be horizontal, 
but the capitals so placed, that the deviation of every line of 
the entablature surmounting them from a straight line might 
correspond to the addition made in the centre of the stylobate.
