Mirrors always stand out, having the right balance between functional and aesthetic in home decoration. During the XV century, round convex mirrors called Oeil de Sorcière (French for “sorcerer’s eye”) were a must-have ornamental piece in the luxurious houses of the aristocracy. These convex mirrors are called "witches' mirrors" because they were attributed magical powers. Placed in front of a window, they allow diffusion of light inside houses.
