Do you have a reference for that papal quote that you can link?

I say this because I was under the strong impression no one believed the earth to be flat. Yet the myth persists, much to my annoyance.

If you can't back that up, could you please remove it, to avoid spreading rumour?

Of course, if a pope actually did say such a thing, I cheerfully withdraw my comment.

Note: I just checked the amazon reviews of that book. They claim it is rife with error.
