The Problem of Annals 15.44: On the Plinian Origin of Tacitus's Information on Christians

Abstract This article contends with the multitude of suggestions that have been raised recently as to the origin of Tacitus's information on Christians and Jesus, and concludes that, contrary to much popular opinion, the theory that Tacitus's information is a reliable independent witness is likely faulty. It first discusses previous theories that have been proposed, including the hypothesis that Tacitus was reliant on Josephus, official Roman documents, etc., and finds all suppositions for Tacitus being independent of Christian tradition to be specious and reliant on faulty arguments and a lack of convincing evidence. The article presents an alternative solution which is that Tacitus was reliant on the work of his friend Pliny the Younger, both his Letter 10.96 sent to Trajan and likely also discourses he had with him, noting that Tacitus relied on Pliny's works elsewhere and the close relationship the two had, even exchanging each other's works for review and criticism. A number of verbal parallels between Tacitus's work and Pliny's letter also points in this direction. As a result, Tacitus's information on Christians and Jesus likely stemmed from Pliny, who in turn gained it from interrogations of and hearsay from Christians. This has ramifications such as that Tacitus is then not a useful source for establishing the historicity of Jesus or the historicity of the Neronian persecution, as it looks as though he melded Christian tradition with the Great Fire of Rome, which Christians make no reference to for centuries.
