The document discusses ancient bog mummies that have been discovered across northern Europe. Bog bodies are preserved human corpses recovered from peat bogs, dating from as far back as 8000 BC. Due to the acidic and low-oxygen environment of peat bogs, the bodies are often well-preserved, allowing researchers to study how the individuals lived and died. Some bog bodies show signs of violent deaths and ritual sacrifices, providing insights into the religious and cultural practices of prehistoric societies.
