Knowledge Organiser: Medieval Medical Ideas c.1250-1500
Key Terms
- Four Humours: Blood, phlegm, yellow bile, black bile — illness = imbalance; restore balance through bleeding or purging
- Miasma: Bad air from rotting matter believed to cause disease
- Bleeding (phlebotomy): Removing blood via cut vein or leeches to reduce excess blood humour
- Purging: Using laxatives to remove excess bile humours
- Heresy: Belief that contradicts Church teaching — challenging Galen risked this accusation
- Dissection: Cutting open a body to study anatomy — banned by the Church in medieval period
Key Dates
- c.460-370 BC: Hippocrates — develops the Four Humours theory
- c.130-210 AD: Galen — expands theory; writes ~500 medical texts based on animal dissection
- c.500-1000: Dark Ages — monks preserve Galen's texts in monasteries
- 1348: Black Death arrives — medieval medicine completely fails to explain or treat it
- 1543: Vesalius — first human dissections reveal 200+ errors in Galen (end of medieval period)
Key People
- Hippocrates (c.460-370 BC): Greek physician — developed Four Humours; "father of medicine"
- Galen (c.130-210 AD): Roman physician — expanded humours theory; works became 1,400-year medical authority
- Medieval monks: Preserved ancient texts through Dark Ages; without them Galen's work would have been lost
Must-Know Facts
- Four humours: blood (hot/wet), phlegm (cold/wet), yellow bile (hot/dry), black bile (cold/dry)
- Galen's works dominated medicine for approximately 1,400 years
- Church banned dissection — so Galen's animal-based errors were never corrected
- Medieval doctors believed in THREE explanations for disease: miasma, God's punishment, humour imbalance
- The Black Death (1348) killed 30-50% of England — medieval medicine had no explanation or treatment
- AGENT framework: Authority, God (Church), Evidence lacking, No dissection, Theory seemed logical
- Galen made significant errors: jaw = two bones (wrong, it's one); blood passes through heart septum (wrong)
Cross-Topic Links
- → Topic 35 (Church Role): The Church preserved Galen and banned dissection — the same institution that sustained medieval ideas also prevented them from being challenged.
- → Topic 34 (Black Death): The Black Death exposed the total failure of humour-based medicine — the same theories that dominated medieval ideas proved useless against the plague.
- → Topic 36 (Renaissance): Vesalius directly challenged Galen in 1543 — the Renaissance ended the dominance of medieval medical ideas through human dissection.
- → Topic 40 (Germ Theory): Pasteur's 1861 germ theory finally replaced miasma — one of the core medieval explanations — with evidence-based understanding of disease causes.
- → Topic 48 (Modern Medicine): Modern medicine builds on 800 years of change from humours — understanding continuity (authority, theory, government) helps explain how medicine progressed.
Common Mistakes
- Saying medieval doctors "knew nothing": Medieval physicians were learned and intelligent within their framework — they applied Galenic theory logically; the problem was the theory itself was wrong, not that doctors were incompetent.
- Forgetting the Four Humours are Hippocrates/Galen, not medieval inventions: The humour theory was ancient Greek in origin (Hippocrates c.400 BC, developed by Galen c.130–210 AD) — the Church preserved and enforced it; medieval doctors did not create it.
- Treating all medieval medicine as superstition: Herbal remedies often had genuine medicinal properties, and hospitals (monasteries) provided real care — distinguish between wrong theory (humours) and some effective practical treatments.
- Not explaining WHY ideas persisted: Church authority, lack of printing, no universities until 13th century, and no microscopes to see germs — always explain the structural reasons ideas could not change, not just that they did not.
