Roman soldiers at Hadrian's Wall suffered from intestinal parasites

A recent study has examined sediments from an ancient latrine located in the Roman fort of Vindolanda. This border post is situated south of the famous Hadrian's Wall. The scientific team discovered direct evidence that the legionaries suffered from worm infections, shedding light on their daily living conditions 🏺.

Microscopic analysis reveals hidden invaders

Led by experts from the University of Cambridge, the researchers used advanced microscopic techniques to study soil samples. They were able to identify eggs of whipworms and roundworms, two types of parasites that spread through fecal contamination. These organisms could cause malnutrition, severe diarrhea, and chronic abdominal pain, undermining the health and possibly the effectiveness of the soldiers.

Key details of the finding:
  • Location: Latrine at Vindolanda fort, a key camp on the northern frontier of the Roman Empire.
  • Method: Use of microscopy to analyze sediments preserved for centuries.
  • Parasites identified: Eggs of Trichuris trichiura (whipworm) and Ascaris lumbricoides (roundworm).
The war against parasites was lost daily within the camp itself, despite the iron discipline of the Roman military.

Lifestyle habits that facilitated contagion

The constant presence of these parasites indicates that the soldiers handled water or food contaminated with human feces. Although Roman engineering excelled in sanitation, in remote and frontier posts practices could be deficient. The diet, which relied on grain ground in local mills, was a probable route of contagion 🍞.

Factors contributing to the infestation:
  • Sanitation on frontiers: Hygienic practices in distant fortresses did not always follow Roman standards.
  • Diet as a vector: Consumption of contaminated cereals and water during processing and storage.
  • Knowledge vs. Reality: The Romans knew the importance of hygiene, but its application in the field was limited.

A contrast between strength and vulnerability

This study highlights the palpable contrast between the image of an invincible Roman army and the everyday reality of its soldiers. While they demonstrated great effectiveness on the battlefield, within their camp they were vulnerable to these small invaders. Research at Vindolanda allows a better understanding of the challenges of life on the Empire's northernmost frontier, where health was a constant battle ⚔️.
