The mouldings mult next be confidered: and as thefe are
in a different pofition from the fhaft, confequently the light
muff ffrike them differently.
In the examples given, I have fuppofed the aperture, or
point of light, above the top of the column; which is a fitua-
tion highly advantageous to the drawing, becaufe, upon this
principle, there will be a regular ftrong fhadow under each co-
vering member productive of a good effedt.
Hence, in the Ionic, for infiance, the hollow, or upper part
of the cyma-reCta, has a ftrong tirade; and the fwelling part is
light in the center, bearing a tirade downwards as it recedes
back. The corona is alfo light, becaufe the rays come full upon
it; but the cyma-reverfa, dentils, and ovolo, are all in fhadow,
on account of the large projection of the corona, which fcreens
them from the light. The left hand volute projects a fhadow
on the fhaft, and the curved top of each flute does the fame.
Tne lower ends of the flutes are light, for the rays come full
upon them; but the upper part of the fcotia in the bafe bears a
