A Painter must always consider the Place his Painting is to be disposed in, and remark the height of the Plan in which he intends his Figures to be placed; observing when he Designs, that his Sight be as much below the Figure he is upon, as the Place where the Piece is to be exposed, is higher than the Eye of a Spectator: without this Precaution, his Work will inevitably be full of Faults, and can never possibly have a good Effect.
