H18: The Renaissance and Medicine
How the Renaissance brought new ideas in anatomy, surgery and physiology through Vesalius, Paré and Harvey, and why progress was still limited.
📖 What Was the Renaissance?
Key Context: The Renaissance (meaning "rebirth") was a period of cultural and intellectual change that began in Italy in the 14th century and spread across Europe. It encouraged people to question old ideas, observe the natural world directly, and value human achievement - an approach called humanism.
The Renaissance transformed medicine in several important ways:
- Artists like Leonardo da Vinci (1452-1519) began to dissect bodies to understand human anatomy accurately
- The invention of the printing press by Johannes Gutenberg around 1440 allowed new ideas to spread rapidly
- Humanism encouraged people to challenge the authority of the Church and ancient writers
- New scientific instruments (like the microscope, developed from the 1590s) enabled closer observation
Renaissance Change:
Questioning old ideas + Direct observation + Printing press spreading knowledge = Gradual medical progress
However, change was slow because old beliefs (Four Humours, Galen) were deeply entrenched.

🦴 Andreas Vesalius (1514-1564)
Vesalius was a Flemish anatomist who revolutionised the understanding of the human body through careful dissection.
Key Achievements
- Became professor of surgery at the University of Padua in 1537 at the age of just 23
- Performed dissections himself rather than having an assistant do it, which was the normal practice
- Published De Humani Corporis Fabrica ("On the Fabric of the Human Body") in 1543
- The Fabrica contained beautifully detailed anatomical drawings based on his dissections
- Corrected over 200 of Galen's errors, proving that Galen's anatomy of humans was based on animals
Example: Vesalius Correcting Galen
Galen had claimed that the human jawbone was made of two bones (like a dog's), but Vesalius proved it was a single bone. Galen had described the human breastbone as having seven segments; Vesalius showed it had only three. Galen had said the liver had five lobes (as in pigs); Vesalius demonstrated the human liver has no lobes. These corrections proved that Galen's work was based on animal dissection, not human anatomy.
Why Was Vesalius Important?
- He proved that Galen was wrong on specific points, which encouraged others to question ancient authority
- His beautiful, accurate anatomical drawings became the new standard for medical education
- The printing press meant his book could be mass-produced and distributed across Europe
- He established dissection as essential to understanding the human body
Limitations of Vesalius: Although Vesalius corrected Galen's anatomical errors, he did not challenge the Theory of the Four Humours. He did not discover any new treatments or cures. His work mainly benefited physicians and surgeons rather than ordinary people. Many doctors still continued to teach Galen's ideas despite the errors.
🔪 Ambroise Paré (1510-1590)
Paré was a French barber-surgeon whose practical discoveries transformed surgical treatment.
Key Achievements
- Began as a barber-surgeon in the French army, treating wounded soldiers
- In 1536, during the siege of Turin, he ran out of the traditional boiling oil used to cauterise (burn) wounds and accidentally discovered a much better treatment
- He mixed a paste of egg yolks, oil of roses, and turpentine to apply to wounds instead
- The next morning, he found that soldiers treated with his paste were healing well, while those cauterised with boiling oil were in agony with swollen, infected wounds
Example: Paré's Discovery at the Siege of Turin (1536)
Paré wrote: "I was constrained to apply instead a digestive made of egg yolks, oil of roses, and turpentine. That night I could not sleep at my ease, fearing that by lack of cauterisation I would find the wounded dead of poison. I raised myself early to visit them, when beyond my hope I found those upon whom I had applied the digestive medicament feeling little pain, their wounds neither swollen nor inflamed, and having slept through the night. The others whom I had applied the boiling oil were feverish with much pain and swelling about their wounds."
Ligatures Replace Cauterisation
- Paré developed the use of ligatures (tying off blood vessels with silk thread) to stop bleeding during amputations
- This replaced the brutal practice of cauterisation with a red-hot iron
- Ligatures reduced pain and the risk of infection compared to burning
- However, ligatures were slow to adopt because they were time-consuming and required skill
Why was Paré significant? Paré proved that observation and experience were more reliable than following ancient texts. His discoveries were made by chance, but he had the intelligence to recognise what was working. His work directly improved the treatment of surgical patients and saved lives. However, he was a barber-surgeon, not a physician, so the medical establishment initially looked down on his work.
Paré's Methods:
Observation + Experiment + Practical experience = Better treatments
Old method (cauterisation with boiling oil) replaced by new method (soothing paste and ligatures)
Observation + Experiment + Practical experience = Better treatments
Old method (cauterisation with boiling oil) replaced by new method (soothing paste and ligatures)
❤️ William Harvey (1578-1657)
Harvey was an English physician who discovered the circulation of the blood, overturning Galen's theory of how the body worked.
Galen's Theory (Before Harvey)
Galen believed that blood was produced in the liver from food and then flowed outward through the veins to the body's extremities, where it was consumed. He thought arteries carried a different substance called "pneuma" (vital spirit). According to Galen, blood did not circulate - it was continuously produced and used up.
Harvey's Discovery
- Harvey studied at Padua University in Italy (1599-1602), where he learned about anatomy and the new scientific approach
- He became physician to James I in 1618 and later to Charles I
- Through careful dissection and experimentation, he proved that blood circulates continuously through the body
- Published De Motu Cordis ("On the Motion of the Heart and Blood") in 1628
Harvey's Evidence:
- He calculated that the heart pumps more blood in half an hour than the liver could possibly produce from food - so the blood must circulate and be reused
- He demonstrated that veins have one-way valves that only allow blood to flow towards the heart
- He proved that the same blood flows through both arteries and veins in a continuous circuit
- He showed that the heart acts as a pump, pushing blood through the arteries and receiving it back through the veins
Example: Harvey's Experiment with Veins
Harvey showed that if you tied a bandage tightly around an arm, the veins below the bandage would swell with blood, while the arteries continued to pulse normally. This proved that blood flows through veins towards the heart. When he pressed on a vein and then released the pressure, he could see blood refilling the vein from one direction only, proving the existence of one-way valves.
Why Was Harvey's Discovery Important?
- It disproved Galen's theory that had dominated medicine for over 1,300 years
- It demonstrated the power of careful observation and experimentation
- It established a new understanding of how the body works
- It laid the foundation for later developments in understanding disease and treatment
Limitations of Harvey: Harvey could not see the capillaries (tiny blood vessels connecting arteries and veins) because they are too small to see without a microscope. Without this missing link, some people doubted his theory. It took over 30 years for his ideas to be widely accepted. Also, like Vesalius, Harvey did not develop any new practical treatments - his work was about understanding, not curing.
🖨️ The Printing Press
The invention of the printing press was one of the most important developments for the spread of new medical ideas.
Impact on Medicine
| Before the Printing Press | After the Printing Press |
|---|---|
| Books were copied by hand by monks - slow and expensive | Books could be mass-produced quickly and cheaply |
| Only a few copies of each book existed | Hundreds of identical copies could be produced |
| Books were only available to the very wealthy and the Church | More people could afford to buy books and learn to read |
| Errors were common in hand-copied texts | Identical copies meant fewer errors |
| The Church could control what was published | Much harder to suppress new ideas |
Key Dates: Johannes Gutenberg invented the movable-type printing press around 1440 in Mainz, Germany. By 1500, over 20 million volumes had been printed in Europe. Vesalius' Fabrica (1543) was one of the first major medical texts to be printed with detailed illustrations, ensuring his discoveries spread across Europe.
🔬 The Royal Society
The Royal Society, founded in 1660, became one of the most important forces for promoting scientific knowledge, including medicine.
Key Features
- Founded on 28 November 1660 at a meeting at Gresham College, London
- Received its Royal Charter from Charles II in 1662
- Motto: "Nullius in verba" ("Take nobody's word for it") - emphasising the importance of evidence and experiment
- Published Philosophical Transactions from 1665 - the world's oldest scientific journal still in print
- Members (Fellows) included Robert Boyle, Robert Hooke, and Isaac Newton
Why the Royal Society mattered for medicine: It provided a forum where scientists could share and discuss new discoveries. It promoted the scientific method - ideas had to be proven by experiment, not just accepted on authority. It published research that could be read across Europe. It encouraged doctors to test new treatments rather than simply following Galen.
Example: The Royal Society and Blood Transfusion
In 1666, the Royal Society supervised experiments in which blood was transfused between animals. In 1667, Jean-Baptiste Denys in France (communicating with the Royal Society) performed the first documented human blood transfusion, giving a patient blood from a sheep. While this was extremely dangerous and later banned, it demonstrated the new experimental approach to medicine.
☠️ The Great Plague of 1665
The Great Plague was the last major outbreak of bubonic plague in England, killing an estimated 100,000 people - roughly a quarter of London's population.
Key Facts
- The plague arrived in London in early 1665, spreading rapidly through the crowded, unsanitary streets
- At its peak in September 1665, over 7,000 deaths were recorded in a single week
- King Charles II and his court fled London in July 1665
- Those who could afford to left the city - the poor had no choice but to stay
Responses to the Great Plague
| Response | Details | How Effective? |
|---|---|---|
| Quarantine | Infected households were locked up and marked with a red cross. Watchmen guarded the doors. | Mixed - it confined the healthy with the sick, increasing infection within households |
| Searching bodies | Searchers examined corpses to determine the cause of death | Ineffective - they had no medical training and often recorded deaths incorrectly |
| Shutting up houses | All residents of an infected house were confined inside for 28 days | Partially effective - it slowed the spread but caused great suffering to the uninfected trapped inside |
| Herb remedies | People carried posies of herbs, burned fires in the streets | Ineffective against the plague, though the smoke may have driven away some fleas |
| Fleeing | Those with money left London for the countryside | Effective for those who fled early, but it spread plague to other areas |
Comparing 1348 and 1665: After over 300 years, many responses to plague had barely changed. People still relied on prayer, herbs, and fleeing. However, there were signs of progress: the government was more organised in its response, quarantine was enforced more systematically, and the Great Plague was the last major plague outbreak in England (partly because of the Great Fire of London in 1666, which destroyed the crowded wooden houses where rats thrived).
📊 How Far Did Medicine Progress in the Renaissance?
Progress: Vesalius corrected Galen's anatomical errors and proved dissection was essential. Paré improved surgical techniques and reduced suffering. Harvey discovered the circulation of the blood. The printing press allowed new ideas to spread rapidly. The Royal Society promoted the scientific method.
Continuity and Limitations: The Four Humours was still widely believed throughout the Renaissance. No new cures or treatments were developed for most diseases. Ordinary people still relied on prayer and herbal remedies. Harvey's discovery did not immediately lead to better treatments. The Great Plague of 1665 showed that medicine was still largely helpless against major disease outbreaks. Progress affected the wealthy and educated far more than ordinary people.
Why was progress slow?
1. The Church still opposed some new ideas
2. Traditional beliefs (Four Humours) were deeply ingrained
3. There were still no microscopes powerful enough to see germs
4. Most people could not read or afford printed books
5. Discoveries in anatomy did not automatically lead to new treatments

✅ Answers
- Vesalius proved that the human jawbone is a single bone, not two bones as Galen had claimed. He showed this through human dissection, proving Galen's anatomy was based on animals.
- Paré discovered by accident that a soothing paste of egg yolks, oil of roses, and turpentine healed wounds far better than the traditional treatment of cauterisation with boiling oil. This was significant because it proved that observation and experience were more reliable than following ancient texts, and it directly reduced the suffering of patients.
- The printing press helped medicine by allowing books to be mass-produced cheaply, meaning new ideas spread rapidly across Europe. Before printing, books were copied by hand - slow, expensive, and error-prone. Vesalius' Fabrica (1543) was printed with detailed illustrations, ensuring his anatomical corrections reached doctors across Europe. The press also made it harder for the Church to suppress new ideas, as many identical copies existed.
- Similarities: both outbreaks saw people relying on prayer, herbal remedies, and fleeing infected areas; quarantine was used in both; the poor suffered most in both. Differences: in 1665, the government was more systematic (households were officially shut up with red crosses, watchmen appointed, searchers employed); the Royal Society existed by 1665, promoting scientific observation; the 1665 plague was the last major outbreak in England, partly due to the rebuilding after the Great Fire of 1666.
- A balanced answer should discuss: the revolution argument (Vesalius, Paré, Harvey all made groundbreaking discoveries; printing press transformed communication; the Royal Society promoted science); the limited change argument (Four Humours still dominant; no new cures for ordinary people; Great Plague showed medicine still helpless; discoveries in anatomy did not translate to treatments). A clear judgement is needed.
- Harvey proved that blood circulates continuously through the body, pumped by the heart through arteries and returned through veins. He showed that veins have one-way valves and calculated that the heart pumps more blood than the liver could produce, proving circulation. This was important because it disproved Galen's 1,300-year-old theory and demonstrated the power of careful observation and experimentation.
🎯 Exam Tips
- Always use specific names and dates: Vesalius published in 1543, Harvey in 1628, Paré's discovery at Turin in 1536
- For "how far do you agree" questions, present evidence for AND against the statement
- When comparing events (like 1348 vs 1665), structure your answer around similarities and differences
- Explain why things happened, not just what happened
- Link factors together: the printing press helped Vesalius' ideas spread; the Royal Society built on Harvey's experimental approach
- Remember that progress was uneven - anatomy advanced faster than treatments
- Use the language of analysis: "however," "despite this," "on the other hand," "this suggests"

⚠️ Common Errors
Watch Out!
Students often think medieval medicine was entirely backward. Wrong: Medieval medicine was entirely backward Correct: Medieval doctors used rational observation (urine analysis, pulse checking) alongside religious approaches. Monasteries preserved medical texts and some hospitals provided genuine care.
Students often think one individual caused all medical progress. Wrong: One individual caused all medical progress Correct: While individuals like Pasteur were crucial, their discoveries depended on other factors: technology, government support, and the work of predecessors.
Students often think progress in medicine has been steady and continuous. Wrong: Progress in medicine has been steady and continuous Correct: Medical progress was not a straight line — there were periods of regression, and some ideas took centuries to be accepted.

8 marks: Explain why the Renaissance led to medical progress.
One reason the Renaissance led to medical progress was the work of Andreas Vesalius, who published De Humani Corporis Fabrica in 1543. Vesalius performed dissections himself rather than having an assistant do it, and corrected over 200 of Galen's errors — proving, for example, that the human jawbone is a single bone, not two as Galen had claimed. Vesalius showed that Galen's anatomy was based on animal dissection, not human, which encouraged others to question ancient authority. The printing press ensured his beautifully illustrated book spread rapidly across Europe.
A second reason was the invention of the printing press by Johannes Gutenberg around 1440. Before printing, books were copied slowly by hand, meaning new ideas spread only gradually and the Church could suppress dissent. After printing, Vesalius' Fabrica (1543), Harvey's De Motu Cordis (1628), and other medical texts could be mass-produced and distributed across Europe within months. The press made it far harder for the Church or conservative physicians to suppress new discoveries.
A third reason was the work of individuals like Ambroise Paré and William Harvey. Paré discovered by accident in 1536 that a soothing paste of egg yolks, oil of roses, and turpentine healed wounds better than cauterisation with boiling oil, and later developed ligatures to replace the brutal practice of burning wounds with red-hot irons. Harvey published De Motu Cordis in 1628, proving that blood circulates continuously through the body, pumped by the heart — disproving Galen's 1,300-year-old theory that blood was produced in the liver and consumed by the body.
However, the Renaissance also showed the limits of medical progress. The Great Plague of 1665 killed approximately 100,000 people in London — a quarter of the city's population — and doctors were still helpless against it. People relied on the same responses as in 1348: prayer, herbs, and fleeing. In conclusion, the Renaissance brought significant advances in anatomy and surgery through individuals like Vesalius, Paré, and Harvey, supported by the printing press, but these discoveries did not immediately translate into better treatments for ordinary people or the ability to combat epidemic disease.
