A 1,500-year old piece of papyrus recently re-discovered in a U.K. university library contains some of the earliest documented references to the Last Supper and ‘manna from heaven.’ The papyrus fragment with Greek writing, held by the University of Manchester’s John Rylands library since 1901, has also been identified as one of the world’s earliest Christian charms. Experts believe that the fragment originated near the ancient Egyptian town of Hermoupolis.
