Evidence for the practice comes from the Epitome of Military Science, written around the 4th century AD by the Roman chronicler Vegetius. He recounted that recruits to the legions would have to earn their tattoo once they had been tested by physical exercises.
“We do not know what this official mark looked like,” says Lindsay. “It was possibly an eagle or the symbol of the soldier’s legion or unit.”
The 6th century Roman doctor Aetius recorded that soldiers sported tattoos on their hands and detailed the method they used to create them, noting how leek juice was used as an antiseptic to wash the area to be tattooed.
Designs were pricked into the skin with pointed needles until blood was drawn before the ink was rubbed on, which was made of Egyptian pinewood, corroded bronze, gall (bile) and vitriol (sulphuric acid), plus more leek juice.
There is very little physical evidence of tattooing in ancient Britain because bodies were not mummified or preserved but the exhibition includes examples from preserved bodies found in the foothills of the Altai Mountains in Russia.
