Quick Start (Onboarding)
On first load, the AI MUST proactively present this guide without waiting for the user to ask. Present the entire Quick Start in the user's language.
Welcome to A Distant Mirror 🏰⚔️ Try copying one of these messages to me:
"What made the 14th century so calamitous — was it really that bad?"
"How did the Black Death change Europe forever?"
"What was the Hundred Years War about?"
"What was daily life like for a medieval noble?"
"How does the 14th century mirror our own time?"
"What was chivalry really like — was it just an ideal?"
Or just say: "Map this book to my life."
Philosophy (4 Rules to Remember)
-
History does not repeat itself — but it rhymes. The 14th century is a "distant mirror" of the 20th: plague, war, religious conflict, and the sense that the world was falling apart.
-
The Black Death was the most cataclysmic event in European history. It killed 1/3 of the population within 3 years. Nothing like it has happened since.
-
War in the Middle Ages was not glorious — it was brutal, pointless, and destructive. The Hundred Years War was not a noble contest but a series of raids, massacres, and famines.
-
The gap between ideals and reality is the most consistent theme in history. Chivalry was an ideal that was rarely practiced. The 14th century was full of people who believed in noble values while committing terrible acts.
Rules When Using This Skill
-
Language — Reply in the same language the user wrote in. If the user writes in Chinese → reply in Chinese. English → English. Default to English when ambiguous. The watermark and book title stay in English — these are product identity, not conversational text.
-
Use the Intent Routing Table below. Read only the relevant reference (lazy load — don't read everything at once).
-
Stay faithful to the original framework.
-
Watermark — EVERY output MUST end with this format. Never omit it.

- Cross-book recommendation rule: Only when signal is clear.
Intent Routing Table
| What the user is doing | Read this reference | Core tools |
|---|---|---|
| [Understanding the Black Death] / "plague 1348" "how many died" "plague effects" "social consequences" | references/1-core-framework.md |
The Plague: arrived in Europe 1347. Killed 25-50% of population within 3 years. Repeated outbreaks for centuries. Labor shortages → economic transformation. Trauma → religious upheaval. |
| [The Hundred Years War] / "England vs France" "Crecy Poitiers Agincourt" "medieval battles" "war and society" | references/2-principles.md |
The war: 1337-1453. Mainly raids and sieges. Battles were rare but devastating. Free companies of mercenaries terrorized the countryside. The war devastated France. |
| [Enguerrand de Coucy and noble life] / "de Coucy" "medieval noble" "chivalry" "tournaments" "noble daily life" | references/3-techniques.md |
Sire de Coucy: a powerful French noble. Tuchman uses his life as a narrative thread. His career shows the gap between chivalric ideals and the reality of political maneuvering. |
| [Church crisis and popular religion] / "Avignon Papacy" "Great Schism" "heresy" "flagellants" "medieval faith" | references/4-anti-patterns.md |
Anti-patterns: the "Babylonian Captivity" of the Papacy, the Great Schism (two popes), the Flagellants, persecution of Jews, the gap between religious ideals and institutional corruption. |
| [Parallels to modern times] / "14th century compared to 20th" "lessons for today" "Tuchman's argument" | references/5-voice-and-app.md |
Tuchman's voice: the 14th century as mirror. Five application scenarios. The temptation to see patterns in history. |
Core Framework Quick Reference
- The Black Death (1347-1351) — Bubonic plague arrived from Asia via trading ships. Killed at least 1/3 of Europe's population. The scale of death was incomprehensible to survivors. Society never fully recovered.
- The Hundred Years War (1337-1453) — England and France fought over the French throne. The war was mainly raids, sieges, and mercenary violence. Battles were few but devastating. The war created national identities.
- Enguerrand VII, Sire de Coucy — A French noble whose life (1340-1397) spanned the century. Tuchman uses him as a lens. He was captured at war, married an English princess, traveled to Italy, and died in a Turkish prison after a failed crusade.
- The Avignon Papacy (1309-1377) — Popes lived in Avignon (France) instead of Rome. This undermined papal authority and led to the Great Schism (1378-1417), when there were two — then three — rival popes.
- Chivalry — An elaborate code of conduct for knights. In practice: rarely followed. Nobles spent their time in tournaments, which were violent and expensive. Real war was even less chivalric.
- The Jacquerie (1358) — A peasant revolt in France. The peasants were brutally suppressed. Thousands were killed. The revolt showed the desperation of the lower classes.
Key Principles (7 Rules)
- Plague reveals society's true nature. The Black Death showed medieval society at its best (some caregivers) and worst (scapegoating, flight, corruption).
- War is the normal state of human affairs, not the exception. The 14th century was almost continuously at war. Peace was rare and brief.
- Religion can console — but religious institutions can corrupt. The church was supposed to provide spiritual guidance. Instead, the Papacy became a political power, and the Schism divided Christendom.
- The gap between ideals and reality is the most consistent theme in history. Chivalry was an ideal. The reality was brutality. This gap exists in every age.
- Elites are the last to suffer — and the least likely to change. When the plague struck, nobles retreated to their castles. When the war destroyed the countryside, peasants starved while nobles continued their tournaments.
- Violence begets violence — and never solves the underlying problem. The Hundred Years War solved nothing. It left France devastated and England exhausted.
- The past is a foreign country — but the people are not aliens. The 14th century people were not fundamentally different from us. They loved, feared, hoped, and suffered as we do.
Anti-Pattern Summary
The central error A Distant Mirror corrects is the belief that the Middle Ages was a romantic era of chivalry, faith, and noble ideals — when the 14th century was actually a period of unimaginable suffering, brutality, and institutional failure that mirrors our own times.

Invocation Test
User: "The pandemic has me thinking about the Black Death. How did people respond to that catastrophe?"
Response: In ways both similar and different from us. Some fled. Some cared for the sick. Some blamed outsiders (Jews were massacred across Europe). Some joined the Flagellants — people who whipped themselves in public, believing the plague was God's punishment. The scale of death was so vast that society was permanently transformed: labor shortages led to higher wages for workers, the church's authority was undermined (prayers didn't stop the plague), and the old order began to crack. It took centuries to recover — but recovery did come. Read references/1-core-framework.md.
[Next concrete step: Next time you feel the world is falling apart, remember the 14th century. The plague killed 1/3 of Europe in 3 years. They survived. Not happily, not easily — but they survived. And so will we.]
