However, there are at least half a dozen non-Christian (that is to say Roman or Jewish) sources that refer to Christian origins. These are sufficient to provide some confirmation of the historical picture that is painted by the Bible. Some of the most important of these sources are: Tacitus, Pliny the Younger, Suetonius, The Babylonian Talmud, Josephus, and the letter of Mara Bar-Serapion.
