Was Mark's Gospel written in Rome?

Mark's Gospel is traditionally said to have been written in Rome, and that is indeed possible. However, it is more likely that if Mark was written in Rome, it would have been written in Latin, a language which the author seems to have known. There seems little point in writing in a language that many Romans would not have understood.

As Mark was written in Greek Koine, it was more likely written somewhere in the eastern empire, where this was the language spoken. On this evidence, it was not written in the Jewish communities of Palestine, where Aramaic would have been the language of choice.
