Lights and Shadows add a surprizing Grace to the Faces of Persons placed at the entrance of a dark Room; every body who fees them will be charm'd, provided they be well disposed; and so as that the Shadow'd side of the Face, may appear obscured by the darkness of the Place towards which it is turned; and at the same time the Lightened side, be further illumined by the brightness of the Air, which is diffused all over it, and by which Means the Shadows become almost insensible on that side: This augmentation of Light and Shadow, gives Figures a great Relievo, and an uncommon Beauty.
