[expand]Baltic mythology preserved elaborate narrative about Saule and Mėnulis’s relationship—not abstract allegory requiring interpretation but explanation for observable astronomical patterns requiring acknowledgment. The sun goddess and moon god were married in primordial time. Their union was proper and productive, creating ordered cosmos where day and night alternated in regular pattern, where solar warmth and lunar cool balanced each other, where celestial harmony produced terrestrial stability.
But Mėnulis was unfaithful. He pursued Aušrinė—the morning star, Venus, the brilliant celestial object visible at dawn and dusk. This betrayal disrupted cosmic harmony. Saule discovered the infidelity and demanded separation. The divorce was permanent—sun goddess and moon god could no longer occupy same sky simultaneously except during rare brief encounters when their paths crossed during solar eclipses or moments of alignment.
This myth explained observable reality: sun and moon were rarely visible together. When one appeared, the other typically remained hidden. Their simultaneous presence was unusual event requiring special ritual attention and often interpreted as dangerous omen. The astronomical fact—that earth’s rotation and celestial mechanics create patterns where sun and moon occupy opposite sky positions—was encoded in narrative form accessible to non-astronomical population requiring practical knowledge of celestial behavior without demanding technical understanding of orbital mechanics.
The story also explained lunar phases. Mėnulis’s monthly disappearance was his shame—hiding from sun goddess’s wrath, retreating into darkness to avoid confrontation with betrayed wife. His gradual return was hope for reconciliation—cautiously emerging, testing whether Saule would tolerate his presence, progressively growing braver until reaching full illumination representing maximum confidence before inevitable decline into next period of hiding.
Thunder god Perkūnas intervened as cosmic judge. When discovering Mėnulis’s betrayal, he struck the moon god with lightning—cutting him into pieces visible as lunar phases. This explained why moon appeared to change shape rather than maintaining consistent form like sun. The waxing and waning were reconstruction and destruction, the god being repeatedly punished and partially restored in endless cycle reflecting his offense against divine marriage and cosmic order.
