Kimberley, you wrote: "Many questions are still unanswered, but essentially, the Alexamenos graffito offers us a window into a very “real” response to a Christian living in Rome." No-one can really say what a christian was in the second/third century. That history has been largely erased. After the early church fathers, it was a different matter. We then have a crucified Jesus, the so-called son of god, developed from the garbled accounts of the Antiquities attributed to Josephus. I see the graffiti as a reaction to the imposition of Jesus as a saviour crucified, by the church fathers. The graffiti artist was some lowly person in the imperial household. This was not anti-christian as such, but was critical of the churches' propaganda being promoted. A christian, whether Jew or Gentile was a follower of the prophets and their books. The 'artist' obviously knew his/her bible and that his audience would immediately recognise it. His idea of an Asses head on the body of the crucified Jesus was taken from Numbers 22:28. The artist was saying, in effect, your religion (the church father's) is rubbish.
