Forlorn, again, this is a question of words, definitions and semantics.
Is the globe round? Of course.
Is the globe just the flat land? No, not in my opinion.
What is the globe? It could be defined as the world, which includes the earth/land, sky/heavens, firmament, sun/moon/planets. That is, a dome-globe, dome-earth model.
Did the pagans use the word 'globe' to talk about land only? Yes, it appears so.
Did the Middle Ages use the world 'globe' to mean the earth/land or all of creation? I don't think it's consistently used in one way.
