The Nine Rosettes and Kabbalah

[Oocephalus]

I don't know much about Kabbalah, but I'd like to note that IMO the small T-O map is used to mark the location of continents: the upper right rosette thus is marked to represent Europe.

Of course this could also be true, but if so, what are the other rosettes? However, I have to admit that I can't explain why each rosette looks the way it does, my idea would just explain the general layout and the two circles at top right and bottom left. Note the three tiny connected circles in the one at bottom left, I think these could be the "three lights". 
This does not necessarily mean that the author was Jewish (although it is possible), as some Christians studied Kabbalah as well.
