The first light is not white. It is the color of a clay oven, warm and diffuse, arriving at an angle so low that every vertical surface becomes a sundial. Shadows stretch beyond measure. The world is mostly shadow at this hour, with thin channels of orange light running between buildings like water finding its level.

The shadows shorten perceptibly. The stone plaza changes from amber to a warm parchment tone as the sun climbs above the rooflines. This is the hour when the gnomon's shadow first touches the western hour marks — the first readable time of day.

Light becomes functional. It is no longer a spectacle but a medium — the plaza is legible, inscriptions can be read, the stone grain is visible. Shadows retain their length but lose their orange cast. The color of light is approaching neutral.

The shadow has crossed the midmorning line. Contrast increases. The sun is high enough that the gnomon's shadow falls in a definite, measurable direction. Precision begins. Time is no longer approximate — it is inscribed in geometry.

The light whitens. The plaza surface loses its color cast and becomes a neutral reflector. Shadows are short, dense, sharply defined. The gnomon's mark falls close to the noon line. One can feel the approach of the meridian — the moment when the shadow points true north.

Nearly overhead. The shadow is a small dark pool directly beneath the gnomon. The plaza is at maximum luminance — every surface flooded, every detail visible, no mystery left. This is the hour of full exposure. Nothing is hidden.

The meridian. The gnomon's shadow falls directly along the noon line — due north in the northern hemisphere. This is the moment the sundial was built to measure: solar noon, when the sun crosses the local meridian. The shadow is shortest. Time is at its most precise. After this moment, the afternoon begins its mirror of the morning.

The shadow begins its afternoon journey toward the east. The light remains white but the quality shifts — afternoon light has a weight that morning light does not. The stone plaza seems to absorb rather than reflect.

The shadow lengthens again. The sun descends. The first faint warmth returns to the light — not the orange of dawn but a subtle yellowing, the beginning of the golden hour's long approach. The gnomon's mark stretches toward the eastern quadrant.

The light golds. Shadows grow theatrical — long enough to create compositions, warm enough to color the stone. The plaza is no longer neutral; it has taken on the amber cast of late afternoon, and every inscription seems deeper in its groove.

The golden hour. Light arrives almost horizontally, painting every surface with warmth. The gnomon's shadow is a long diagonal arm pointing east-northeast. The sundial's final hours are its most beautiful — time told in amber and proportion.

The shadow exceeds the dial plate. It falls beyond the plaza's edge, into the street, across the facing wall. The gnomon can no longer tell accurate time — the sun is too low, the shadow too long, the geometry too extended. This is the hour the sundial stops working. What remains is just the light, fading.
