Why the rosettes image may not be a map at all

[MarcoP]

ok, very nice, but let me ask you: if you can draw naked ladies, why should one draw 72 pipes when you want to display angles ?

The artist shows he is able to draw waves in 3D on the Rosette page and he can draw depth (see the sunken tower).

I think Searcher's "3D rendering" does an excellent job at presenting a possible interpretation for the central rosette.
The six pillars seem to me strongly suggestive of the "pillars of heaven" (a concept that, as Searcher suggests, has been widespread in many cultures).

In my opinion, the pipes possibly represent the winds. In this case, I see no particular reason to think the winds were meant to be personified as angels as in the Bellifortis illustration linked You are not allowed to view links.

What would be much less common in this interpretation is that the winds apparently blow from the center, while they typically blow from the "outside space" towards the Earth which is at the center of the diagram.
