A lead sarcophagus was not per se unusual in Roman times; several hundred examples have been found, but none have been configured like the one in the photo above.
The discovery of the 1,700-year-old body was made in the ancient city of Gabii, 20 kilometres from Rome, by a team of researchers including McMaster University visiting professor Jeffrey Becker.
"Instead of being in a box, the lead is more of a wrapping," Becker says. "The person was wrapped inside sheets of lead folded around the body, crimped at the end and kind of folded into a seal."
Researchers would like to study the contents of the container without unfolding or otherwise damaging it, but they realize that xray and CT scans will not be possible.
