How did the role of the government during the Great Plague compare to the Black Death?

During the Great Plague of $1665$, the government took a much more active role by issuing royal decrees and hiring specific officials. This was a significant increase in organization compared to the more localized and uncoordinated response to the $1348$ Black Death.

What is the difference between humoral treatment and the practice of 'transference'?

Humoral treatment aimed to balance internal fluids through methods like bleeding or purging. Transference, however, was the belief that the disease could be physically moved out of the body into another object or animal, such as a live chicken.

Contrast the effectiveness of quarantine versus the killing of domestic animals in $1665$.

Quarantine was effective because it physically isolated the infection, whereas killing cats and dogs was harmful. By removing these predators, the government allowed the rat population—the true carriers of the plague fleas—to increase rapidly.

Why is it a common error to associate bird-masked plague doctors with the Black Death?

Plague doctors with bird-like masks were a specific development of the Renaissance period and were not used during the $1348$ Black Death. Their attire was designed around the miasma theory, which became more prominent in the $17$th century.

What was the actual consequence of the government's order to cull cats and dogs?

The cull was intended to stop the spread of disease, but it actually worsened the epidemic. It removed the natural predators of rats, allowing the rat population and their plague-carrying fleas to multiply and spread the infection further.

Did $17$th-century physicians understand the role of fleas in spreading the plague?

No, physicians in $1665$ had no knowledge of bacteria or the flea-rat vector. They primarily blamed miasma (poisonous air), astrological alignments, and supernatural causes like divine punishment for the outbreak.

What was a 'pomander' and why did people carry them during the plague?

A pomander was a small container filled with sweet-smelling substances like spices or perfume. People carried them to sniff because they believed that pleasant smells could counteract the 'miasma' or bad air that was thought to spread the plague.

Define the role of a 'searcher' during the $1665$ epidemic.

Searchers were officials, often women, hired by parishes to find and inspect those who had died. Their job was to identify whether the cause of death was the plague so that the household could be officially quarantined.

What was the 'Great Plague' and when did it occur?

The Great Plague was a massive outbreak of bubonic plague that struck England in $1665$. It killed approximately $100,000$ people in London alone and led to a temporary collapse of normal social and economic life.

Why were plague doctor masks designed with a long beak?

The beak was stuffed with aromatic herbs and spices like mint or lavender. This served as a primitive filter intended to protect the doctor from breathing in 'miasma,' which was believed to be the primary transmission route of the disease.

The Great Plague

Summary

The Great Plague of 1665 was the last major bubonic plague epidemic in England, resulting in the deaths of approximately $100,000$ people. It represented a critical period in medical history where traditional medieval beliefs in humoral balance and miasma coexisted with increasing government-led public health interventions.

1. Definition & Core Concepts

Epidemic Profile: The Great Plague was a severe outbreak of bubonic plague in London, characterized by the growth of painful buboes and high mortality rates.
Timeline: Although the plague returned periodically, the $1665$ event was the most devastating since the $14$ th century, prompting a total shift in urban life.
Biological Reality: Modern science identifies the bacterium Yersinia pestis, spread by fleas on rats, as the cause, though this was unknown to people at the time.

2. Underlying Principles

Miasma Theory: The prevailing scientific belief was that "bad air" (miasma) caused the plague. This air was thought to be released from the soil during warm weather or created by rotting filth.
Humoral Imbalance: Physicians continued to apply the Theory of the Four Humours, suggesting that the plague was a result of an internal fluid imbalance triggered by external factors.
Supernatural Beliefs: Many viewed the epidemic as a divine punishment for sin or linked it to astrological events, such as the unusual planetary alignment observed in $1664$ .
