A Request for Evidence

The Document Reopened
Lia examines the source
Casaubon shows Lia the original Provins text after describing the Plan. She asks to see the document rather than accept his account of its meaning.
A different approach
She consults a local guide and studies the wording, focusing on ordinary commercial details rather than mystical clues. Her method reverses the group's assumptions.
A Merchant's List

Mundane Details
Local geography
Lia identifies the named places as streets and landmarks in Provins. The text records hay wagons, cloth, rose deliveries, quantities, and prices.
Abbreviations misread
She explains that a merchant's abbreviation and repeated item marks were mistaken for dates and instructions. The supposed sequence of centuries collapses into routine accounting.

The Plan's Emotional Hold
The authors' investment
Casaubon admits Lia's reading is persuasive but resists abandoning the Plan, which has shaped his work and imagination for years.
