Content Summary

The late 1490s were defined by The Last Supper (1495–1498), an experimental disaster using oil on dry stone. Concurrently, his Paragone manifesto argued for the scientific supremacy of painting over sculpture and poetry.

Technical Deep-Dive

The Last Supper's composition is modeled on wave acoustics; Christ’s words act as a stone creating emotional ripples. Paragone arguments focused on "fatica corporale" (physical labor) versus "fatica d'ingegno" (intellectual exertion) of optics.

Evidence Ledger

Codex Urbinas (Paragone text); Lady with an Ermine reflectography.

Agent Hook

Model the chemical reaction between Leonardo’s oil base and the damp walls of the refectory.

Cross-Reference Mapping

Wave theory in The Last Supper connects to hydrodynamic studies in the Codex Leicester.

Uncertainty Markers

Commission; Painting as Science goal; Ermine as biological vs heraldic study.
