Memory Aids: Lock In the Key Facts

The four factors that enabled the Renaissance — "PWCI":

• Printing press (1440s) — spread new ideas across Europe unstoppably
• Weakened Church (Reformation, 1517) — permitted dissection at Italian universities
• Culture of observation — Renaissance spirit valued "see for yourself"
• Individual genius — Vesalius, Paré, Leonardo da Vinci

Key dates for this topic:

• 1440s — Gutenberg's printing press developed
• 1514-1564 — Vesalius's life dates
• 1517 — Protestant Reformation begins (Luther) — weakens Church authority
• 1537 — Vesalius appointed Professor of Anatomy at Padua
• 1543 — Vesalius publishes The Fabric of the Human Body
• 1552 — Paré publishes his work on ligatures

Vesalius's specific errors in Galen — learn at least two:

• Human jaw = ONE bone (Galen said two)
• Human liver = TWO lobes (Galen said five)
• Heart septum has NO holes (Galen said blood passed through invisible pores)
• Human breastbone = THREE parts (Galen said seven)

"Ideas not treatments" — the key essay distinction: Renaissance changed what doctors KNEW (anatomy) but not what they DID (still bleeding and purging). Think of it as updating a map without changing the roads: the map is now accurate, but until roads are built differently, journeys remain the same. Similarly, Vesalius gave medicine an accurate map of the body — but the roads (treatments) did not change until later developments (germ theory, anaesthetics, antiseptics).
