C4 - The Impact of the Renaissance on Britain Flashcards

1
Q

What was the Renaissance?

A

A cultural movement that began in Florence, Italy in the late 1400s. It began because wealthy businessmen paid scholars to investigate the writings of the ancient Greeks and Romans. People were inspired to be critical of the old texts and experiment with new ideas. It made educated people want to find things out for themselves rather than just accept what the church told them. It caused a ‘rebirth’ of learning and a belief that being educated in science, art, music and literature could make life better for everyone.

Q

How did the Renaissance spread?

A

Before the Renaissance, books were rare and expensive because they were copied out by hand. The invention of the printing press in 1451 made books cheap, accurate and quick to produce.

Q

What were the consequences of the Renaissance?

A

New lands - explorers and merchants used more accurate maps, discovered the Americas and brought back new foods and medicines
Printing - new ideas spread quickly as well as those of the ancient world
Art - this showed the human body in more realistic detail
New inventions - technology such as gunpowder caused new types of wounds
New learning - a more scientific approach to learning involving observation, hypothesis, experiment and questioning.

Q

What did Vesalius do?

A

He wrote a beautifully illustrated, very accurate textbook on anatomy based on dissections and observations of the human body called ‘The Fabric of the Human Body’ (1543). He corrected Galen’s mistakes as he also dissected animals. He provided proof of Galen’s mistakes, for example the breastbone in a human has three parts, not seven like the ape. Vesalius did dissections himself and he said that medical students should learn from dissection.

Q

What was the impact of Vesalius on medicine?

A
  • his work overturned centuries of belief that Galen’s study of anatomy was correct
  • he was a Renaissance approach because his work was based on examination of the human body itself
  • Vesalius transformed anatomical knowledge
  • although Vesalius’ work did not lead to any medical cures, it was the basis for better treatments in the future
  • he showed others how to do proper dissections, and famous sixteenth century anatomists followed his approach e.g. Fabricius and Fallopius.

Q

What were treatments for gunshot wounds like before Paré?

A

Gunshot wounds were thought to be poisonous and were burned out using boiling oil, then a cream of rose oil, egg white and turpentine was applied.

Q

What did Paré do that changed the way gunshot wounds were treated?

A

In 1537, Paré run out of hot oil when treating soldiers so he just used the cream. The patients’ wounds healed well - better than those who had had the oil as well. He wrote a book about treating wounds (1545).

Q

What method did Paré use to stop bleeding?

A

Paré used Galen’s method of tying blood vessels with ligatures or thread. He invented the ‘crow’s beak clamp’ to stop bleeding. The ligature was less painful than cauterisation, but it took longer and could introduce infection - it was also less effective in battlefield surgery, which needs to be as quick as possible.

Q

What did Paré do to help amputees?

Q

How did Paré contribute to medical progress in England?

A
  • he translated the work of Vesalius and used Vesalius’ work in his book ‘Works on Surgery’ (1575)
  • this was widely read by English surgeons - an English hand-written version appeared in the library of the Barber-Surgeons of London in 1591
  • Queen Elizabeth I’s surgeon William Clowes made Paré’s work well-known and described him as the ‘famous surgeon master’
  • he copied Paré’s burn treatment method using onions in 1596
  • he said that gunshot wounds were not poisonous and wrote about stopping bleeding from wounds in his book ‘Proved Practice’ (1588)

Q

Who was William Harvey (1578-1657)?

A

An English doctor who challenged Galen by saying that blood circulated around the body.

18
Q

What was Galen’s belief about blood?

A

Galen believed that new blood was constantly being made in the liver and burned as a fuel in the body.

19
Q

How did Harvey discover the circulation of blood?

A
  • he calculated mathematically the volume of blood that would need to be produced if it was a fuel for the body
  • he observed the slow-beating hearts of animals to understand how the muscles worked
  • he read widely what the Italian anatomists at Padua discovered and built upon their work
  • he dissected and studied human hearts
  • he experimented pumping liquid the wrong way through valves in the veins, proving that blood could only go around one way
20
Q

What could Harvey not explain about blood circulation?

A

He did not know why the blood circulated, why there was different coloured blood in the veins and arteries and how the blood got from the arteries to the veins.

21
Q

Why was Harvey criticised?

A

He was challenging Galen and the idea of bloodletting to balance the four humours

22
Q

What was the reaction to Harvey’s discoveries?

A

His critics said he was mad or ignored his ideas. Some doctors rejected his theory because he was contradicting Galen, or because they did not believe his calculations. Despite this, his theory was accepted by many doctors. It wasn’t until 1661, four years after Harvey died, that a good enough microscope was made to see the capillaries connecting arteries and veins.

23
Q

What was the significance of Harvey’s discovery?

A

It was not immediately useful. Transfusions did not happen until 1901, when blood groups were discovered. Today, understanding of the blood and its circulation is significant because it allows us to quickly test and diagnose illness, and to carry out advanced surgeries like organ transplants.
