Plague of 664

Plague of 664 is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Plague of 664 rather than just read about it. In short: The plague of 664 was an epidemic that affected Great Britain and Ireland in 664 AD, during the first recorded plague pandemic. It was the first recorded epidemic in English history, and coincided with a solar eclipse.

Key takeaways

  • Plague of 664 belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Plague of 664 to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Plague of 664 from memory before moving on to harder problems.

Reference excerpt

The plague of 664 was an epidemic that affected Great Britain and Ireland in 664 AD, during the first recorded plague pandemic. It was the first recorded epidemic in English history, and coincided with a solar eclipse. It was considered by later sources as "The Yellow Plague of 664" and said to have lasted for twenty or twenty-five years, causing widespread mortality, social disruption, and abandonment of religious faith. The disease responsible was probably bubonic plague – part of the First Plague Pandemic – or else smallpox. The general absence of rat bones in archeological sites may suggest that the plague was partially pneumonic.

Chronology According to the Irish Annals of Tigernach, the plague was preceded by a solar eclipse on 1 May 664. The path of the total eclipse started in the Pacific, crossed the Gulf of Mexico, swept along the eastern coast of North America, crossed Ireland and Britain, and continued on into Central Europe. Bede also mentioned the eclipse, dating it incorrectly to 3 May, possibly to better align with the Roman (Dionysian) calendar. The Irish sources claimed that there was also an earthquake in Britain. The plague struck first in Kent, possibly carrying off Archbishop Deusdedit and King Earconbert, who Bede records as having both died on 14 July 664. It then spread to Essex, causing widespread rejection of Christianity and reversion to paganism under Kings Sighere and Sæbbi. The pestilence reached Ireland on 1 August 664, arriving first at Mag Nitha, among the Fothairt in Leinster. Ireland and Great Britain were equally affected by the disease, though the little written evidence that has survived was written by the English. The plague also reached Northumbria that autumn, killing Bishop Cedd in Lastingham on October 23, 664, and Bishop Tuda and Boisil, prior of Melrose, around the same time. The swift transmission of the disease from south to north implies transmission via ship rather than overland travel. After 664, the plague declined but outbreaks continued, such as at Gilling between c. 666–669, Barking between c. 666–675, Lichfield in 672, Ely in 680, and a more generalized return during 684–687. After 687, contemporary records of plague-related deaths and healing miracles cease, and the population seems to have recovered by the early 700s.

Contemporary accounts Bede, writing of the plague, said that it "ravaged the country far and near, and destroyed a great multitude of men," and that "scarcely any inhabitants [were] left in villages and places which had been thickly populated, and some towns were wholly deserted." Though the predominant theory of plague was divine retribution, Bede does not assign it any cause. Historian John Maddicott suggests that "the plagues of the seventh century were too widespread, and came too evidently in a period of religious growth and prosperity, to be easily seen as the result of God’s anger turned against a particular people." According to Adomnan of Iona, a contemporary Irish abbot and saint, the plague ravaged most of the British Isles excepting a large part of modern Scotland. Adomnan considered the plague a divine punishment for sins and believed that the Picts and Irish who lived in northern Great Britain were spared from the plague due to the intercession of St. Columba who had founded monasteries among them. Adomnan personally walked among victims of the plague and claimed that neither he nor his companions fell sick. A few specific accounts of the disease have survived. Cuthbert, an Irish monk, was reportedly "seized stricken down with a plague which at that time carried off very many throughout the length and breadth of Britain." It is possible that a groin bubo grew on Cuthbert's thigh. The wife of King Ecgfrith, Etheldreda, died with a tumor that released a "noxious moisture," another possible instance of the Black Plague in Ireland. Abbess Æthelthryth of Ely succumbed to a "large tumor under her jaw," likely a plague bubo.

Legacy This plague, and the memory of it, provided the inspiration for Julius Caesar's legendary cursed sword, Crocea Mors (Yellow Death), in Geoffrey of Monmouth's Historia Regum Britanniae.

Worked examples

Example 1 — a first encounter with Plague of 664

Start with the simplest possible case. Write down what Plague of 664 claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Plague of 664 before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Plague of 664 ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Plague of 664

In research
Plague of 664 appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Plague of 664 in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Plague of 664 is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1st-millennium health disasters, 664, 7th-century disasters, so understanding it makes those chapters shorter.
In everyday life
Look for Plague of 664 outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
