4. Civilization and Disease Circa 8000 B.C.E. - Agriculture and Sedentism: > close contact with animals > stagnant pools of water > accumulation of human waste Circa 3000 B.C.E. – Cities > Large, dense populations sustain diseases like measles, smallpox

5. The Word ‘Plague’ “Plague” can be traced back to the Latin word “plaga” meaning blow or wound, not necessarily associated with disease (Aberth 2011: 1).

6. The Nature of the Disease Bacterium = Yersinia pestis Spread both by fleas and human contact Three types: bubonic; pneumonic; septicemic

7. Bubonic Plague

8. Pneumonic Plague Infection of the respiratory system Rarer and more virulent than bubonic plague Usually kills within 2 days

9. Septicemic Plague Infection in the blood stream Bleeding from the nose and eyes, bloody urine Usually kills in 24 hours or less

10. Nota Bene Some outbreaks of disease called plagues weren’t plague: Plague of Athens (430 – 426 B.C.E.) and the Antonine Plague (164 – 180 C.E.) were probably smallpox. (Aberth 2011: 22)

20. Medieval Explanation: Miasma “... a miasma or substantial corruption of the air, either from a higher source (ie. the planets) or a lower one (swamps, rotting corpses, earthquakes etc.).” (Aberth 2011: 38)

21. Medieval Cures “... the typical contemporary response to the plague was to do what their predecessors had done, only to do it more intensely and more urgently...” (Aberth 2011: 38)

22. Medieval Recognition Of Contagion “Out of the hundreds of plague treatises I have consulted from fourteenth- and fifteenth- century Europe, there are none that I know of that deny contagion, on religious or any other grounds.” (Aberth 2011: 41)

23. Gentile da Foligno

24. Contagion By Sight “To justify plague contagion by sight... an anonymous practitioner from Montpellier in 1349 quoted at length from Euclid’s theory of optics...” (Aberth 2011: 41)

25. God’s Will “only He who binds can unbind” (Jacre d’Agramont quoted in Aberth 2011: 43).

26. Natural Explanation Giovanni della Penna: “unskilled and ignorant physicians say that it proceeds from Gods or from the heavens,” (Aberth 2011: 43).
