SANDERSON, William, Graphice. The use of the Pen and Pensil. Or, the most Excellent Art of Painting: In Two Parts, London, Robert Crofts, 1658.1 quotations
After some practice with the Pen (which follows the use of the Cole) proceed to shadow, with black and white Chalks, in stroakes, or sweetning (as in Painting).
For better directions herein, get some Designes or draughts, done in Chalke, Red-oaker, dry Colours, Croyons, or Pastills, for your patterns.
RICHARDSON, Jonathan, An Essay on the Theory of Painting. By Mr. Richardson. The Second Edition, Enlarg'd, and Corrected, London, A. C. - A. Bettesworth, 1725.1 quotations
The Thoughts, and Finishings are in a great Measure seen in the Prints of such Works of which Prints are made, nor is a Drawing destitute of Colouring absolutely ; on the contrary, one frequently sees beautiful Tints in the Paper, Washes, Ink, and Chalks of Drawings ; But what is wanting in some respects is abundantly recompenc’d in Others, for in These Works the Masters not being embarrass’d with Colours have had a full Scope, and perfect Liberty, which is a very considerable Advantage, especially to some of them. There is a Spirit, a Fire, a Freedom, and Delicacy in the Drawings of Giulio Romano, Polydoro, Parmeggiano, Battista Franco, &c. which are not to be seen in their Paintings : A Pen, or Chalk will perform what cannot possibly be done with a Pencil ; and a Pencil with a thin Liquid only what cannot be done when one has a Variety of Colours to manage, especially in Oil.
