Via Atlas Obscura, in Italy is a famed collector’s assortment of artifacts bearing the physical imprint of souls trapped in agony attempting to reach our world:
Located on the banks of the Tiber, the tiny century-old Piccolo Museo Del Purgatorio, or “Museum of the Holy Souls in Purgatory,” holds a collection of bibles, prayer books, tabletops, and articles of clothing said to have been singed by the hands of souls in purgatory.
According to Catholic belief, the soul is stranded in purgatory until it atones for its sins. The scorched handprints and other burn-marks collected in this museum are believed to be the product of souls begging their earth-bound loved ones to pray harder.
Victor Jouet, collector and French missionary, was supposedly inspired to build this purgatorial museum after a fire destroyed a portion of the original Chiesa del Sacro Cuore del Suffragio, leaving behind the scorched image of a face that he believed to be a trapped soul.
