Had you read my post properly, Clanad, you would have realised that I didn't claim the Annals as a whole were from the 15th Century but the specific passage under discussion, the implication being that the passage was an interpolation. In support of this are the fact that in the early 3rd century, Clement of Alexandria, specifically charged with searching non-Christians sources for passages in support of the historicity of Christianity fails to cite what, if real, would be a significant piece of evidence. Tertullian made have made the claims you cite above, yet he did not cite Tacitus, with which he was familar, in support. Nor did Eusebius, as mentioned previously.
Your claim that Tacitus did use the term 'Christus' is circular reasoning if it is an interpolation, but given you hadn't understood my post correctly, you're forgiven for this error.
Moreover, the claim within the specific passage goes on to say, "Accordingly, an arrest was first made of all who pleaded guilty; then, upon their information, an immense multitude was convicted, not so much of the crime of firing the city, as of hatred against mankind." Given Tacitus' reputation for measured language, the claim that "an immense multitude" was convicted is at odds with the known spread of Christianity.
I think your point about the Pilate stone is stretching it a bit. While this information may well have been lost over the centuries until the discovery of the stone, it's unlikely that this was information unknown to an Imperial historian writing a relatively short time after the events. A later interpolation does explain the confusion of terms (although I'm not suggesting that this alone proves that is what had occured).
I don't recall your request for a CV and can't be bothered to see if I can find either it or what your point in requesting it might have been, though I'm sure it definitely would have been astonishingly clever and devastating to me to have had to do so. I'm sorry to discover you've been anticipating its posting all this time. If I ever feel the need to justify myself to you, I will certainly post it and alert you to its presence.
