Chemistry & Corpses: The Science of Bog Bodies

TL;DR

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

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.
