_The Architecture of ~Vignola~ put in Perspective; and first, the
Pedestal of the ~Tuscan~ Order._
Since every one is acquainted with _Vignola_’s Architecture, I determine
not to alter it, but to explain it, with its general and particular
Rules; measuring the same with Modules, after the usual manner. He
therefore that has it not, may find it in the following Figures, and
at the same time learn the Method of putting it in Perspective. And
whereas the Drawing the Plan, Elevation and Profile of what’s to be
built, is no less necessary for him that studies Perspective, than for
the Architect, the first performing in Appearance, what the latter does
in Reality; I have therefore here delineated the _Tuscan_ Pedestal, with
its Plan, as you see in AB, that you may the better apprehend what I said
in the foregoing Figure, That from all the Angles of Projecture in the
Elevation, Lines must be let fall on the Plan; this being of absolute
necessity for finding the Correspondence of the Angles with the Lines in
the Perspective Projection. Observe, that what I always call Length, as
from F to G, is that from which proceeds not only the Foreshortning of
the Plan; but also that which I call the Profile E. Wherefore, in the
opposite Pedestal of the same Figure, you’ll see a contrary Disposition
of the Whole.
I shall not here repeat, how the finish’d Pedestal is taken from these;
having so largely spoken of that before; but briefly tell you, that the
Angles of the first Out-line of the Profile E give the level Lines of the
Face D, and the Angles of the Plan give all the Perpendiculars.
