Investigating History and Disease Through Archaeology and Genetics

Genetics and Archaeology: Complementary Insights Into the Past

This section introduces the author's perspective on how archaeological and genetic research provide complementary insights into the past. Roberts argues that archaeology, as a historical science, allows us to understand past societies through the physical remains of their culture, technology, and even their skeletons. This perspective complements written history by offering insights into the experiences of everyday people and giving an alternate viewpoint from historical documents. Genetics, especially through the use of aDNA, allows us to further investigate ancestry, kinship, and how pathogens evolve, adding another dimension to our comprehension of history.

Archaeology Explores Past Societies: Material Culture, Daily Life, Social Impacts

Roberts emphasizes that archaeology doesn't just serve history; it offers a unique perspective on past societies. By studying artifacts like pottery, tools, and buildings, archaeologists can reconstruct aspects of daily life, trade networks, and social structures. Unlike written history, which often focuses on elites and political events, archaeology provides a more holistic understanding of past societies, including how common individuals lived, even those who might have been absent from documentation. In this book, Roberts will use archaeological evidence to understand the daily lives of people living in leprosy hospitals, the social dynamics of the massacre on St. Brice's Day, and the occupational hazards faced by the crew aboard the Mary Rose.

Practical Tips

• Start a personal "archaeology diary" to document your everyday life for future generations. By keeping a detailed record of your daily activities, thoughts, and the cultural context in which you live, you're creating a primary source that could one day offer invaluable insights into the early 21st century, much like archaeological findings do for past societies.
• Map your own trade networks by tracking where your purchased goods come from for one month. Use a world map to mark the origins of items like your clothes, electronics, and food. This will give you a visual representation of your personal trade network and help you grasp the complexity of ancient trade systems.
• Volunteer for a local historical preservation project or community archaeology dig. While you might not be conducting the dig yourself, participating in these activities can give you a hands-on understanding of how archaeologists uncover the lives of past individuals. It also helps preserve the heritage and provides a tangible connection to the methodology of archaeology.
• Create a themed book club that focuses on historical events and daily life in past centuries. Each member could read a different book on a similar topic and share insights on the social dynamics and occupational hazards of the time. This collective learning experience can broaden your perspective on history and its impact on modern society.

Genetics and Ancient Dna Trace Ancestry, Kinship, and Pathogen Evolution

Roberts highlights the revolutionary impact of genetics in archaeology. By extracting and analyzing ancient DNA found in archaeological discoveries, we can trace ancestry, kinship relationships, and the evolution of pathogens. aDNA analysis allows us to understand migration patterns, population changes, and how diseases affected past societies. Roberts will use aDNA analysis to investigate the origins and spread of diseases like leprosy and plague, the genetic predispositions to diseases like Paget's disease, and the kinship connections between individuals buried in different locations, such as those killed in the St. Brice's Day slaughter in Oxford and a man buried in Denmark.

Practical Tips

• Engage in educational games and apps that simulate disease outbreaks. Look for interactive tools that allow you to understand how diseases spread and are controlled. For example, a game might simulate the spread of a plague in a historical setting, allowing you to make decisions that affect the outcome. This hands-on approach can give you a practical understanding of the principles behind disease spread and containment.

Crypt Summary Secular Versus Ecclesiastical Power During the Medieval Period: Church and Relics Tension

This section focuses on the interplay of secular and religious authorities in the Middle Ages. Roberts describes how the Church, a powerful institution with economic, political, and social influence, played a significant role in shaping medieval society. She explores the Church's involvement in governance, social care, and propaganda, using leprosy hospitals as an example of how it mediated the needs of the poor and sick while also obscuring marginalized communities. Roberts also highlights the importance of saints and relics as sources of Church power, particularly through the example of Thomas Becket's martyrdom and the Church's use of his cult to exert authority over the monarchy.

The Church: A Multifaceted Religious, Political, Social Institution

Roberts describes the Church as a multifaceted institution during medieval times, wielding power not only through its religious teachings but also through its influence on politics, social welfare, and communication. As a powerful entity with vast landholdings and economic resources, the Church played a significant role in shaping medieval society, influencing governance, promoting charitable activities, and disseminating...

Crypt Summary Genetics and Archaeogenomics: Unlocking Disease History and Reconstructing Early Existence

This section highlights the transformative impact of archaeogenomics in understanding the historical trajectory of illnesses and reconstructing past lives. Roberts describes how ancient DNA (aDNA) has resolved long-standing debates about the origins and spread of diseases such as the plague, but also reveals previously unknown details about individual and population experiences of diseases like leprosy and Paget's. Roberts further discusses how aDNA analysis can reveal unexpected details about ancient communities, such as the presence of different sexes in prehistoric Britain.

Genetics Revolutionizing Our Knowledge of Plagues Throughout History

Roberts argues that archaeogenomics has completely revolutionized what we know about plague. Before aDNA analysis, the origin of the Black Death, along with the First and Third Plague pandemics, was debated, with various possibilities including anthrax, typhus, tuberculosis, and hemorrhagic fever. aDNA analysis finally confirmed that the cause of all three pandemics was Yersinia pestis.

Crypt Summary Insights Into Disease Evolution and Epidemiology Through Scientific Study of Past Remains

This section focuses on the use of scientific techniques, including osteological analysis and aDNA, to comprehend the evolution and epidemiology of specific diseases. Roberts discusses how the skeletal remains of individuals with leprosy, Paget's disease, and syphilis offer insights into the history and progression of these afflictions, and how genetic analyses have challenged traditional narratives about their origins and spread.

Leprosy: An Illness With a Past Revealed by Bones

Roberts explores leprosy as an illness with a profound history written in the bones of those who were afflicted with it. Leprosy, caused by the bacterium Mycobacterium leprae, was widespread in medieval Europe, leading to social stigma and the establishment of leprosaria to isolate those with the disease. Roberts uses the bones from St. Mary Magdalen Hospital, Winchester, to understand the experience of leprosy and how medieval societies reacted to disease.

St Mary Magdalen Hospital's Leprosy Rate & Medieval Attitudes

Roberts discusses how the leprosy hospital at St. Mary Magdalene had a surprisingly large percentage of people in its cemetery with osteological signs of the disease. The...
