The Moon and the SunThis thread follows Yves’s rise as a royal natural philosopher, his concealment of the sea people’s humanity, and his painful acceptance of responsibility.

The Successful Expedition

The King’s Natural Philosopher
Achievement
Yves locates and captures sea people, fulfilling the commission that brought him royal favor. His method relies on observation and collected reports.
Blindness within success
He regards the captives as specimens, not people. His confidence in inquiry does not yet protect him from the assumptions that shape his conclusions.
The Dissection

Anatomy Under Royal Eyes
A demonstration
Yves dissects a male sea person before court and visitors. Marie-Josèphe records the anatomy as the living female’s cries disturb the proceedings.
Discovery
A peculiar lung lobe attracts the King’s interest. The finding draws Yves deeper into a search for immortality than his natural philosophy can justify.
The Father’s Demand

A Priest Under Scrutiny
Religious discipline
Pope Innocent questions Yves’s neglected religious duties and considers sending him to a monastery. Yves fears that losing royal patronage would end his research.
Conflicting authorities
The exchange exposes the tension between scientific curiosity, priestly obedience, and the political need to please the King.
The Lie of Immortality

A Claim Without Proof
False assurance
Yves tells Louis XIV and Pope Innocent that the sea person’s organ has the hoped-for effect. He has no proof, but the claim protects his own position and keeps the question open.
Immediate damage
The lie makes the sea woman’s life more precarious and weighs on Yves’s conscience. His pursuit of royal approval has displaced the honesty on which inquiry depends.
A Penance of Preservation

From Discovery to Repair
Confession
Yves admits that he lied. Pope Innocent assigns him the task of finding and correcting records that misrepresented the sea people.
Secret archive
In the epilogue, Yves preserves forbidden books, letters, drawings, and the sea monster’s remains. His research becomes an act of historical restitution rather than royal advancement.
