In the first chapter of Artists’ Pigments 1600-1835, R.D. Harley discusses her sources for the research into the history of pigments which follows. As a cartographer, the following quotation from Henry Peacham (1576-1644) on page 7 caught my eye:
I could wish you now and then, to exercise your Pen in Drawing and imitating Cards and Mappes; as also your Pencill in washing and colouring small Tables of Countries and places, which at your leisure you may in one fortnight easily learn to doe; for the practice of the hand doth speedily instruct the minde, and strongly confirme the memory beyond any thing else; nor thinke it any disgrace unto you, since in other Countries it is the practice of Princes, as I have shewed heretofore; also many of our young Nobilitie in England exercise the same with great felicitie.
