Song Meaning
The lyrics paint a picture of the Moon, personified as a vain celestial being bored with her routine. She descends from the sky, seeking admiration and a reflection of her beauty in earthly waters, specifically a lagoon and the sea. This initial descent is driven by a desire for self-appreciation, leading her to mistake the sea's foam for her own crystalline whiteness, a moment of self-deception born from vanity.
The central tension arises from the Moon's obsessive pursuit of being the most beautiful, a trait explicitly labeled as "vanidosa" (vain). This vanity leads her to alter her very nature. Bored with her full, round form in the night sky, she desires a more slender figure. She even implores the Sun to dim a light and asks the sky for a dark, olive-colored veil, suggesting a desire to change her appearance and perhaps even her role, moving away from her natural luminescence.
The craft here is in the personification and the subtle, almost melancholic, consequences of the Moon's vanity. Her attempts to "tighten her figure" and change her appearance result in her becoming "so slender" that she often doesn't grow, appearing "like a thorn." When she tries to illuminate the sea, her light is reduced to a "little grain of salt that walks." This imagery starkly contrasts her former, presumably grand, luminescence with a diminished, almost insignificant presence, highlighting the unintended diminishment that comes from trying too hard to be something she's not.
What makes these lyrics resonate is the gentle, almost wistful portrayal of a desire for beauty leading to a loss of self. The Moon's quest for admiration results not in greater glory, but in a fading, a reduction of her own light and presence. The lyrics suggest that true beauty might lie in embracing one's natural form and purpose, rather than in the endless, often self-defeating, pursuit of an idealized image.
