There is more information on Gadifer de la Salle in Google Books. - - Too much for now.
Apparently, he came from a literary family, fought for the Teutonic Knights (which gives "eastern" connections), and survived Nicopolis (along with John the Fearless of Burgundy)- all before the Canary Islands' expedition. He was back in Paris afterward, involved on the Armagnac side.
The key to the VMs cosmic illustration is the structure of the cosmic diagram. The BNF Fr. 565 manuscript is dated c. 1410 and was property of the Duke of Berry (d. 1416) and then his daughter Marie.
It seems rather unlikely that Gadifer would have crossed paths with the BNF manuscript, though they may have been in Paris at the same time.
