The writing that claims to be a letter addressed by Dionysius the Areopagite to the Timothy of the New Testament on the occasion of the martyrdom of the apostles Peter and Paul in Rome is not included among the epistles usually associated with other works that bear the name of the same person as author, and its history must be investigated independently of theirs. It was composed originally in Greek, although it no longer exists in that language. To the material for the critical study of this epistle the author now adds an unprinted Arabic translation that appears not only to have been made directly from the lost original Greek, but also to show that an Arabic form lies back of the other versions. The document is reproduced with literal exactness.
