WHAT DO YOU see now? Globes of red, yellow, purple. Just a moment! And now? My father and mother and sisters. Yes! And now? Knights at arms, beautiful women, kind faces. Try this. A field of grain—a city. Very good! And now? A young woman with angels bending over her. A heavier lens! And now? Many women with bright eyes and open lips. Try this. Just a goblet on a table. Oh I see! Try this lens! Just an open space—I see nothing in particular. Well, now! Pine trees, a lake, a summer sky. That's better. And now? A book. Read a page for me. I can't. My eyes are carried beyond the page. Try this lens. Depths of air. Excellent! And now! Light, just light making everything below it a toy world. Very well, we'll make the glasses accordingly.
