Quotation

Traveller,
            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.
                        Friend,
            This must require a very Dexterous and quick Hand.
                        Traveller.
            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.
