Chap. CLXII.—How to represent Night.
Those objects which are entirely deprived of light, are lost to the sight, as in the night; therefore if you mean to paint a history under those circumstances, you must suppose a large fire, and those objects that are near it to be tinged with its colour, and the nearer they are the more they will partake of it. The fire being red, all those objects which receive light from it will appear of a reddish colour, and those that are most distant from it will partake of the darkness that surrounds them. The figures which are represented before the fire will appear dark in proportion to the brightness of the fire, because those parts of them which we see, are tinged by that darkness of the night, and not by the light of the fire, which they intercept. Those that are on either side of the fire, will be half in the shade of night, and half in the red light. Those seen beyond the extent of the flames, will be all of a reddish light upon a black ground. In regard to their attitudes, let those who are nearest the fire, make screens of their hands and cloaks, against the scorching heat, with their faces turned on the contrary side, as if ready to run away from it. The most remote will only be shading their eyes with their hands, as if hurt by the too great glare.
