in the next section, a pitch authorized by Vitruvius,
somewhat higher : which, I think might well be estab-
lished for all pediments universally.

Upon the raking corona is to be placed the mould-
ing called cyma recta by the Italians ; by Vitruvius,
Simœ ; strangely explained by Perrault, as exposed
above in last Section p. 238 : and by the Greeks, «¿W«,
L e. on-iset, or coping. This cyma Tecta, though very
beautiful, is not a constituent of a cornice, as before ob-
served, for if it was, it could not be omitted in the front
cornice under the pediment ; when it has place on the
side cornice, it returns over the raking corona, and mi-
tres in the angle of the corona beneath, by ordinates
transferred from that on the side, to that placed on the
taking corona, where by this method, it does not pro-
ject equal to it's height, in which the perfection of this
moulding, in particular, consists ; it would be better,
therefore, when the pediment front is the most conspi-
cuous and principal elevation of a structure, to give
this moulding it's due height and projecture over the
pediment, and transfer it to the side one, which had
better be seen in a sally, a small matter, too much, than
that on the pediment too little.

On this last moulding, which is in fact the coping
*>f the pediment, are usually placed blocks of stone,
with soles or bases cut to the raking, and the sides of
-the blocks perpendicular, and at top have a corona
with it's cymatium, and sometimes only a cymatium ;
one of these blocks called by Vitruvius acroteria, stands
right over the angular column, right and left, and in
front and flank in the same perpendicular, as the ground
of the freeze of the entablature; and in height, half the
height of -the pannel; but a third acröter is to stand on

the
