Chemistry & Corpses: The Science of Bog Bodies | Summary and Q&A

TL;DR

Bogs have the unique ability to naturally mummify bodies and preserve ancient specimens due to their low-oxygen, highly acidic environments.

Key Insights

• 🌍 Bogs in northern Europe, particularly in Denmark, Ireland, Germany, and the Netherlands, have preserved numerous prehistoric bodies.
• 😘 The acidic, low-oxygen conditions in bogs prevent decomposition, leading to the preservation of skin, hair, and organs.
• 🖐️ Moss, particularly Sphagnum, plays a crucial role in the formation of bogs by absorbing nutrients from the soil and creating an acidic environment.
• ❓ Bodies found in bogs may have been sacrifices or victims of ancient rituals.
• ❓ The preserved bodies in bogs have provided valuable insights into ancient civilizations and their practices.
• 🔁 Bogs are also used for peat farming, where peat is harvested for various purposes, including soil conditioner and fuel.
• 😥 Bogs can vary in pH levels, which affects the preservation of bodies and other objects.

Questions & Answers

Q: How were the bodies discovered in bogs?

Bodies in bogs were often found by peat farmers using machinery for farming purposes, leading to their accidental discovery and, unfortunately, sometimes destruction.

Q: Why were there bodies in the bogs?

Archeologists believe that ancient Celtic tribes used bogs for religious ceremonies, including sacrifices. The bodies found in the bogs may represent these sacrifices and rituals.

Q: How were the bodies preserved in bogs?

Bogs have low oxygen levels and highly acidic conditions, which prevent bacterial growth and decomposition. The acidic mixture can turn skin into leather but often dissolves calcium phosphate in the bones.

Q: What other objects have been found in bogs?

In addition to bodies, bogs have preserved large packages of butter and lard, which were buried in the bog to prevent them from going rancid.

Summary & Key Takeaways

• Bogs in northern Europe have preserved numerous ancient bodies, including Tollund Man, an iron-age mummy, making it one of the best-preserved prehistoric bodies in the world.

• Bogs form over thousands of years as moss absorbs nutrients from the soil, creating an acidic, anaerobic environment where decomposition cannot occur.

• The chemical processes in bogs, such as the acidity of tannins produced by moss, can preserve skin, hair, and organs, but often dissolve calcium phosphate in the bones.
