Scientists are 99% certain that a skull dug up from beneath the floor of a Polish cathedral is that of astronomer Nicolaus Copernicus. The only way to know for sure is to match DNA from the skull with that of a known relative—a difficult task, since Copernicus was too busy thumbing his crooked nose at the Pope to father any children.
But researchers think they have a solution. They are now preparing another excavation to look for the remains of Copernicus's uncle, the former bishop of Warmia, who is also believed to be buried in Frombork Cathedral. Exactly where, no one is sure. [Link]If it turns out they can't positively identify the bishop's remains, I guess they'll just dig up one of his uncles.
