Why did Paul skip Alexandria? Why is there a blank spot on his missionary map? What prompted him to make plans to travel west rather than south? The lack of scholarly interest in this question is almost as conspicuous as the lack of sources for earliest Christianity in Alexandria. This article surveys and categorises the rather random hypotheses offered in scholarship. They relate to Paul's self-understanding as a missionary, to his theological raison d’être, to religious and cultural aspects, and to political circumstances. The most plausible answer concerns early Christian mission strategy: Paul skipped Alexandria because it was a Jewish city and as such part of the Jewish-Christian mission.
