The ‘Acts of John, according to Prochorus’ is the English translation of a manuscript found in the library of the medieval monastery of St John the Theologian, on the remote Greek island of Patmos. The original text, dating from the 17th century, narrates the apocryphal stories of Christ’s youngest and most beloved disciple. It chronicles St John’s journey from Jerusalem to Ephesus and Patmos and his trials and tribulations. The message of light over darkness and of good over evil prevails in this astonishing story. This is an opportunity both for the casual reader and the academic to follow St John in his later life according to the accounts of his disciple Prochorus.
