Water, earth and air

[Jorge_Stolfi]

Not much for a „copy“, maybe inspired

I imagine that the Author wanted a circular diagram with certain generic features, like the curved roads/rivers/spokes and a representation of the world at the center.  He sketched some of it, and gave the Scribe a book with some version of that Oresme medallion that he could copy the details from.  So the Scribe copied the wolkenband and the T-O thing at the center, and put some stars in between.  But the Scribe did not understand anything of that drawing.  Not even how the wolkenband should be drawn. (But he did learn it before he got to the big fold-out.)

Even ignoring the blue color, both f68v3 and that Oresme drawing have a T-O diagram with the big sector at bottom, surrounded by stars and a wavy border with knobs.  To me, those three matching details cannot be just coincidence...

All the best, --stolfi
