One of Karsh of Ottawa's signature techniques was to separately light these objects for his portrait photographs. A 1908 sculpture originally titled The Ark of the Covenant and later renamed Cathedral depicts two of them. That Rodin sculpture partly inspired a series of pictures that Alfred Stieglitz dubbed "portraits in themselves", which depicted a pair of them belonging to his wife Georgia O'Keeffe. A famous blue-paper drawing by Albrecht (*) Dürer depicts two of them pressed together. An M.C. Escher lithograph depicts a piece of paper on which two of these things use pens to draw each other into existence. For 10 points, name these objects, two of which nearly touch at the center of Michelangelo's The Creation of Adam.
