Copernicus died in Frombork on 24 May 1543. Legend has it that the first printed copy of De revolutionibus was placed in his hands on the very day that he died, allowing him to take farewell of his life's work. He is reputed to have awoken from a stroke-induced coma, looked at his book, and then died peacefully.
Copernicus was reportedly buried in Frombork Cathedral, where archeologists long searched in vain for his remains. In August 2005, a team led by Jerzy Gąssowski, head of an archaeology and anthropology institute in Pułtusk, after scanning beneath the cathedral floor, discovered what they believe to be Copernicus' remains. The find came after a year of searching, and the discovery was announced only after further research, on November 3, 2008.
