Quotation

DESIGN or DRAWING
By these Terms is sometimes understood the expressing our Thoughts upon Paper, or whatever other flat Superficies ; and that by Resemblances form’d by a Pen, Crayon, Chalk, or the like. But more commonly, The giving the Just Form, and Dimension of Visible Objects, according as they appear to the Eye ; if they are pretended to be describ’d in their Natural Dimensions ; If Not, but Bigger, or Lesser, then Drawing, or Designing signifies only the giving those Things their true Form, which implies an exact proportionable Magnifying, or Diminishing in every part alike
And this comprehends also giving the true Shapes, Places, and even Degrees of Lights, Shadows, and Reflections ; because if these are not right, if the thing has not its due Force, or Relief, the true Form of what is pretended to be drawn cannot be given : These shew the Out-Line all round, and in every part, as well as where the Object is terminated on its Back-Ground.
In a Composition of several Figures, or whatever other Bodies, if the Perspective is not just the Drawing of that Composition is false. This therefore is also imply’d by this Term. That the Perspective must be observ’d in the Drawing of a Single Figure cannot be doubted.
I know Drawing is not commonly understood to comprehend the Clair-obscure, Relief, and Perspective, but it does not follow however that what I advance is not right.
