  • “It’s fantastic we can look in such detail at an individual who died 600 years ago,” Dr Walker said. “It’s incredible, really.”

  • The 25 skeletons were uncovered last year during work on Crossrail, a new rail line that’s boring 13 miles (21 kilometres) of tunnels under the heart of the city. Archaeologists immediately suspected the bones came from a cemetery for plague victims.

  • To test their theory, scientists took one tooth from each of 12 skeletons, then extracted DNA from the teeth. They announced Sunday that tests had found the presence of the plague bacterium, Yersinia pestis, in several of the teeth, meaning the individuals had been exposed to — and likely died from — the Black Death.

  • The findings didn’t stop there. Archaeologists, historians, microbiologists and physicists worked together to apply techniques from several scientific disciplines to the discovery.

  • Radiocarbon dating and analysis of pottery shards helped determine when the burials took place. Forensic geophysics — more commonly used in murder and war-crimes investigations — helped locate more graves under the square. Studying oxygen and strontium isotopes in the bones revealed details of diet and health.

  • these were, by and large, poor people. Many of the skeletons showed signs of malnutrition consistent with the “Great Famine” that struck Europe 30 years before the Black Death. Many had back injuries suggesting lives of hard labour. One man became a vegetarian late in life, indicating he may have entered an order of monks.

  • Archaeologists were surprised to discover that the skeletons lay in layers and appeared to come from three different periods: the original Black Death epidemic in 1348-1350, and later outbreaks in 1361 and the early 15th century.
