1495-1498 Last Supper Execution Window
Core event range for production of The Last Supper and for evaluating the tradeoff between technical innovation and long-term surface stability. This dossier links project timing, material method, and conservation-era evidence pathways.

Anchor Snapshot
The Last Supper cluster is a high-impact case where timeline, technique, and legacy quality all converge. It is a key model for how this site separates project-period facts from later restoration-stage interpretation.
Evidence Matrix
| Anchor | Evidence Class | Interpretive Role |
|---|---|---|
| 1495-1498 execution range | Project chronology evidence | Defines the production frame for work-sequence and studio-pressure analysis. |
| Experimental wall technique | Technical method evidence | Explains early deterioration risk and why conservation history is central to interpretation. |
| Copy and restoration chains | Transmission and conservation evidence | Supports reconstruction of original visual intent where surface loss complicates direct reading. |
System Impact: Cast and Patronage
Connects court-level commission pressure with long-cycle project execution decisions.
System Impact: Timeline Logic
Useful stress-test for event date versus project duration modeling.
Open Questions for Next Pass
- How should conservation-era interventions be displayed without flattening the original execution narrative?
- Which copy witnesses should be prioritized as reference anchors for missing detail regions?
- What confidence language is best for public-facing claims about original surface appearance?
