Look up. Before clocks or calendars, there was a pattern that repeated every day: the sun rises, crosses the sky, disappears, and returns. In this lesson, that motion is continuous—the sun does not jump between scenes but follows a single path, even when it passes below the horizon. What changes is our point of view. When visible, it defines the world; when hidden, it continues its journey out of sight. Ancient observers gave structure to that unseen passage and called it the Duat. Here, we observe both the motion and the story layered onto it—one path, seen and unseen.
