Meaning: This quote is from the ancient Roman architect, Marcus Pollio, and it describes the phenomenon of the sun's effect on the moon as it moves towards the eastern sky. In this poetic observation, Pollio captures the changing relationship between the sun, the moon, and the earth as the moon begins to reflect the sun's light in a specific way. The quote signifies a moment of transition and change, as the sun's influence on the moon diminishes and a thin line of light emits its splendor towards the earth.

In astronomical terms, the quote refers to the waxing crescent phase of the moon. This phase occurs when the moon is positioned between the earth and the sun, with the sun's light illuminating a small portion of the moon's surface. As the moon moves towards the eastern sky, the angle of the sunlight hitting its surface changes, resulting in a thin line of brightness along the edge of the moon's illuminated side. This creates a beautiful and ethereal sight in the evening sky, marking the beginning of the moon's journey towards its full phase.

The quote also alludes to the changing intensity of the sun's effect on the moon as it moves across the sky. When the moon is positioned to the west of the sun, the sun's rays directly illuminate its surface, creating a bright and full appearance. However, as the moon moves towards the east, the angle of the sunlight changes, causing the moon to appear less illuminated and creating the thin line of brightness described by Pollio. This transition reflects the dynamic interplay between the sun, the moon, and the earth as they move through their respective orbits in the celestial dance of the cosmos.

The poetic language used by Pollio captures the beauty and wonder of this astronomical phenomenon, highlighting the intricate relationship between the celestial bodies and their effects on each other. The imagery of the thin line of light emitting its splendor towards the earth evokes a sense of awe and reverence for the natural world and the movements of the heavens above.

In addition to its astronomical significance, the quote can also be interpreted metaphorically, symbolizing the idea of transition and change. The shifting phases of the moon, as described by Pollio, can be seen as a metaphor for the cyclical nature of life, with moments of brightness and illumination giving way to periods of darkness and introspection. This interpretation adds a deeper layer of meaning to the quote, inviting contemplation on the universal themes of transformation and renewal.

Overall, Marcus Pollio's quote beautifully captures the timeless beauty of the moon's waxing crescent phase and the shifting interplay of light and shadow in the evening sky. It serves as a poetic reminder of the interconnectedness of the natural world and the enduring power of celestial phenomena to inspire wonder and contemplation.
