According to Augustin Calmet, an 18th-century Bible scholar, Stanisław asked the King for three days to produce his witness, Piotr. The King and court were said to have laughed at the absurd request, but the King granted Stanisław the three days. Stanisław spent them in ceaseless prayer, then, dressed in full bishop's regalia, went with a procession to the cemetery where Piotr had been buried three years earlier. He had Piotr's grave dug up until his remains were discovered. Then, before a multitude of witnesses, Stanisław bade Piotr rise, and Piotr did so.
