The Voynich Ninja

It's interesting how in Chigi, you can already see the cross taking form, but you wouldn't link it to the VM drawing if it weren't for the exaggerated shape of the Riccardiana crosses.

I guess with a lot of goodwill one could see how the Chigi root may give rise to a clawed feline with a tail after a few iterations, but that might be a coincidence.
