Medieval World
Black Death• Caused by the bacterium Yersinia pestis,
which still circulates among humans
• After genetic material from four London victim’s teeth were extracted, teams of researchers have sequenced 99% of the plague’s genome (2011).
• First big pandemic with disseminated Yersinia pestis in humans
Black Death – called so due to the blackened skin of the
victims• A pneumonic infection, highly
contagious, which could be transmitted via inhalation, ingestion, or even a slight abrasion on the skin.
• Lung lesions occur, heart and kidneys turn to fatty goo, and death usually results from heart failure
• The walls of blood vessels hemorrhage
A Little History
•A disease is sometimes so horrible that it stains the fabric of society. Moral and ethical questions surface concerning the cause and treatment of the disease.
?????????????????????
– Why do some people get the disease, while others are spared?
– Is anyone to blame for spreading the disease?
– Is it everyman for himself, or man’s duty to help each other?
A Little History• It was a common belief during the Middle
Ages that the Black Plague was a punishment sent by God for the supposed wickedness and corruption of the times.
• Methods of preventing or treating the plague were often based on magic or the supernatural.
• Medieval doctors had no idea that a bacteria that lived on the fleas was the true cause of the plague
A Little History
• Many doctors who treated the plague fell victim themselves
• Processions of flagellants were common and sometimes the common people joined their parades
• Human greed, worldliness and neglect of religion had caused the plague
Moirai - Fates
Clotho – spins the thread of life
Lachesis – draws off the thread
Atropos – cuts it
One could rise and fall based on the Fates’ actions, even the gods feared them
Black Death – a perfect storm
• Much of the mortality is explained by situational factors
Cooler climate conditions, excess of rain led to failed crop harvests and widespread hunger
Overcrowded medieval citiesImmunocompromised population living
under stressful conditions –
A Little History
• Medieval cities were often crowded, dirty and unhealthy.
• Poor sanitation and a lack of personal cleanliness provided ideal ground for breeding disease
• 1/3 of the population died, leaving workers in short supply. Peasants began to realize their worth and demand fewer taxes and more rights changed the world
Medieval Medicine
• Medievals believed that there were 4 humors in the human body. The balance of these 4 humors was essential for good health. Balance was achieved by diet, medicines and phlebotomy
•Blood – sanguine (social, pleasure)•Phlegm – phlegmatic (relaxed, quiet)•Yellow Bile – choleric (ambition)•Black Bile – melancholy (thoughtful)
Healing• Herbal remedies were
common• Most treatment was
done at home• Given the medical
uncertainty of the time, many medievals turned towards charms, special prayers or rituals
• Rural vs. city
Blood-letting• Allowed for control of
the humors
• Dangers: infection, weakening of the body, cutting an artery instead of a vein, bleeding to death, loss of consciousness
• Blood circulation was not widely accepted until well into the 1500s
The CulpritsThe Culprits
Should we blame the rats??
• 'Rats were carriers but they also died from bubonic plague. If it had been this disease you would expect to find large deposits of 14th century rat bones. These would have survived the centuries in the timber waterfronts in the city, but we found very few bones.'
The Famine of The Famine of 1315-13171315-1317
By 1300 Europeans were farming almost all the land they could cultivate.
A population crisis developed. Climate changes in Europe produced
three years of crop failures between 1315-17 because of excessive rain.
As many as 15% of the peasants in some English villages died.
One consequence ofstarvation & povertywas susceptibility todisease.

Jews were persecuted
• Under the pressure of extreme terror, people sought scapegoats and the alien community of Jews was a natural target
• An additional reason: Jews were involved in money-lending and a debtor could cancel his debt by murdering the Jew who gave him money
• Ex: In Strasbourg, 2,000 Jews were burnt on a great scaffold

“The town I left was filled with dead,and everywhere these queer red fliescrawled upon the corpses’ eyes,eating them away.”
“Fair make you sick,” the merchant said,“They crawled upon the wine and bread.Pale priests with oil and books,bulging eyes and crazy looks,dropping like the flies.”

“I had to laugh,” the merchant said,“The doctors purged, and dosed, and bled;“And proved through solemn disputation“The cause lay in some constellation.“Then they began to die.”
“First they sneezed,” the merchant said,“And then they turned the brightest red,Begged for water, then fell back.With bulging eyes and face turned black,
they waited for the flies.”
