PLATE VIII.
Fig. 1, Plate VIII, is the representation of a Church, in which the Point of Sight C falls near the middle of it: the artist
of course stood opposite to that point, or part of the building, when drawing the object from nature. The two Diminishing
Points are at different distances from the Point of Sight C: that towards which the receding lines of the sides of the building
marked A are drawn, as, a b, h k, f g, and their parallel^ the ridges of the roofs, &c. is situated on the left hand, consider-
ably beyond the margin of the picture; a slip of paper may therefore be joined to the drawing, in order to receive it. But the
sides B and their parallels dimmish at the point marked x upon the end of the Horizontal Line, on the right hand of the object.
To these two points, therefore, all the receding lines must be drawn.
The Church, Fig, 2, is treated in a similar manner. The two Diminishing Points (as is always the case) are one on one side
of the Point of Sight, and the other on the other side. All the receding lines of the sides of the building, marked with the
letter D, as, 1 m, n p, and their parallels, wherever they may be found, must diminish towards the point on the left; but all
the receding lines in the sides F, as 1 p, n f, the ridge of the roof t v, &c. &c. and their parallels, must be drawn to the Di-
minishing Point on the right hand, as is seen by the dotted lines. The tops of several of the windows in these examples are
not flat but arched; and here an attention to the rule so frequently dwelt upon, namely, that the perspective representation of
all lines parallel to each other in nature, must have the same Vanishing Point in the picture, is highly necessary. Thus if the bot-
toms of the two curves, which form the arch over the window in the end of the transept D, Fig. 2, were joined by a line, as
from 1 to 2, that line would evidently be parallel in nature to the line at the bottom of the same plane, 1 m, and consequently
must be directed towards the same Diminishing Point: therefore, although there be no line in reality, care must be taken so to
place the two points 1 and 2, as that, if a line did really join these parts, its direction would be towards the Diminishing Point
of 1 m, n p, &c. The same remark may be made for the parts where the bottom of the roof joins to the main body of the build-
ing, as at w x, where, although a line connecting the two points docs not actually exist, yet the farthest end of the bottom of
the roof x must be so placed with respect to the nearest end w, that a ruler laid from one to the other will be directed towards
the same Diminishing Point, as 1, 2, 1 m, &c. &c. because parallel to those lines in nature.
