Inspiration for Philosophers like Marsilio Ficino?

[GracefulShinjo]

Well I want to propose that the manuscript was created by an alumni of Padua, a German scholar who studied in the University of Padua and later worked in the Visconti court as an alchemist/philosopher, writing a book that fused alchemy with philosophy .....

Are you thinking of a specific person here, or—if it's supposed to be a fictional character—why a German scholar?

 I’m thinking of the inscription at the back. It is speculated that the writer was from Southern Germany (Bavaria, Rhineland Palatinate, Swabia, Baden-Württemberg) based on that charm but I can see them being from Trentino Alto-Adige, Switzerland or Austria.
