ON PERSPECTIVE. [LECT. II.
columns, efpecially of enriched, e.gr. of Corinthian
columns, are decifive, but by no means Angular in-
ftances.
As in the ftudy of mufic, notwithstanding an in-
ftrument may be very accurately conftrucred, and
very nicely toned, to excel in playing on it requires
a good natural ear, improved by attention, and
practice ; fo in the arts of defign, of which per-
fpeclive is a principal part, be the rules ever fo ju-
dicious, clear, demonftrable, and extenfive, yet to
execute any compofition happily, and gracefully,
requires the guidance of an eye accuftomed to ob-
fervation and remark, exercifed in effects of na-
tural objects, fenfible of their moft beautiful combi-
nations, and difpofed, and ready, to imitate them :
thus accompli died, it may juftly hope, not only to
apply with facility the principles of fcience and tafte,
but,
" To {hatch a grace beyond the rules of art."
I have thrown out thefe hints, becaufe I'earneftJy
wifh to diveft this ftudy of every incumbrance by
which it has long been held, as it were, in thral-
dom ; entangled by operofe diagrams, and infinite
radii of lines ; whofe perplexities contribute to ren-
der that difficult and complex, which is, and which
ought to be, reprefented as limple and clear. I ra-
ther delire to difentangle, and to explain, difficul-
ties, where difficulties muft in forne fenfe, be ex-
pected, in which undertaking I have to requeft your
candour, and, if fuccefs crown my endeavours, I
have to expect your applaufe.
