Together with The Lives of the Most Eminent Painters From Cimabue, to the time of Raphael and Michael Angelo. With an Explanation of the Difficult Terms, London, John Gain, 1685.1 quotations
You must know, that the Italians have a Way of Painting their Pallaces, both within and without, upon the bear Walls, and before Oyl Painting came up, most Masters wrought that Way ; and it is the most Masterly of all the ways of Painting, because it is done upon a Wall newly Plaistered, and you must Plaister no more, than what you can do in a Day ; the Colours being to Incorporate with the Mortar, and dry with it, and it cannot be Touched over again, as all other Ways of Painting may : This is that they call Painting in Fresco.
This must require a very Dexterous and quick Hand.
Yes, and a good Judgment too ; for the Colours will show otherwise when they are Dry, than they did when they were Wet : Therefore there is great Practice required in Mannaging them, but then this Way makes amends for its Difficulties ; for the longer it stands, it acquires still more Beauty and Union, it resisting both Wind and Rain.
