About five years after Saint Josaphat’s martyrdom his body was found intact, though the clothing had rotted away. Again in 1637 it was still white and supple. A beautiful silver reliquary was made for it, with a life-size image of the reclining Saint surmounting it. The body was again exposed intact in 1767. It was eventually taken to the Basilica of Saint Peter in Rome. Pope Leo XIII canonized Saint Josaphat in 1867.
