Noble, Thomas; Clark, John Heaviside [Ill.]: Practical Perspective, Exemplified On Landscapes (London, 1809)

Of such a nature is the present design. In it will be found enough of the
Theory of Perspective to enable the Artist to delineate his Landscape with
truth and accuracy; and as few instructions are given without such examples
as are continually the subjects of Drawing, the Pencil is kept in practice,
while the understanding is cultivated; taste and the powers of execution are
exercised, while the judgment is informed.

A very small number of Geometrical Problems, properly selected, will be
found sufficient for every purpose in Landscape Perspective. One Plate for
explanation will make the Learner acquainted with the lines and points by
which this Science performs its operation; and a single demonstration will
make clear to the dullest understanding the reason of those proportions on
which the practice of Perspective is founded.

I consider references as very preferable to repetition; they create a memory,
where that mental principle of Science is wanting, and they recal former
operations which explain each other, and thereby make an easy way to the
understanding. They will be found to be numerous. He whose perception
is strong, and memory tenacious, may think their number troublesome—
he has only to neglect them. To many, the Author believes, he had better
appear somewhat troublesome than in the least obscure.

The support of a candid Public, ever ready to patronize that which tends
to the improvement of the Arts, is respectfully solicited; and with some
confidence; since neither care nor exertion has been spared to render this
work adequate to the utility of its design, and thereby worthy their attention.

THOMAS NOBLE,
