Christopher Hibbert - historian and biographer - writes in two of his books (The Borgias and their Enemies:1431-1519 and The House of Medici: its Rise and Fall) about a curious event during the battle of Fornovo. The Holy League under the command of Francesco Gonzaga is claiming victory because they captured the French King Charles VIII' baggage train. Among the trophies is a book depicting naked women.
Can this book depicting naked women at various times and various places be the Voynich Manuscript?
Before you start laughing, think on the following question: why none of the Prague correspondence regarding the Voynich Manuscript mentions the fact that the book does contain numerous naked woman bodies?
The answer likely is that the Prague scholars were trying to present the book as favorable as they can in front of such prominent scholar as Athanasius Kircher.(Read all the letters posted on Philip Neal's site here )
Now imagine that Franchesco Gonzaga is holding the Voynich Manuscript after the battle of Fornovo and does exactly the opposite of the Prague scholars - he omits mentioning the herbal sections, because he wants to use the naked women painted at various times (the VMs months) and at various places (bathtubs and elsewhere) to degrade and insult the King of France Charles VIII. The attitude of the VMs ladies is declared lascivious and the anatomical drawings (among them male genitalia, supposedly) is declared to be 'sketches of intercourse'. Thus one of the greatest smears in history is commited.
The Book with the naked women is then presented to the Pope along with the relics. The Pope's name is Alexander VI - Rodrigo Borgia. He is Catalan, so is his son Cardinal Borgia. While laughing at the VMs and wondering what exactly the book represents somebody writes the name of the months in the Voynich Manuscript... in Catalan, according to Sean Palmer (visit his work here ).
Let's look at the map of Charles VIII Italian War - 1494-1495.
Among the first stops in the campaign is Pavia, where Charles VIII meets Ludovico Sforza, who is accompanied by Leonardo da Vinci, according to Charles Heaton's Leonardo da Vinci and his Works.
Imagine that you are physician and up until yesterday you were drawing knotgrass and cannabis pictures and suddenly you are in the middle of the meeting between Leonardo and Della Torre. This may inspire you to attempt some anatomy too.
The beginning of the Charles VIII Italian War is in Savoy. Just few years earlier the Duke of Savoy commissioned Jean Colombe to work on the unfinished manuscript Tre Riches Heures du Duc de Berry.
As a person with interest in nature you don't pay attention to the exotic clothes on fol. 51 of the famous book, but you notice the three animals painted on it.
Plus you have a taste for curvaceous women and Jean Colombe did paint the right curves for your taste.
Charles VIII campaign continues and all guns now are pointed at Rome where under the original ceiling of the Sistine Chapel - the stars on blue background - sits the Catalan Pope Alexander VI. Rome falls!
However, by the time the French reach Naples the coins start to flip and Charles VIII is now facing the Holy League on his way back across the Alps. At Fornovo your book is captured and used to smear publicly the King of France. It was supposed to be a treasury of natural knowledge acquired during long year of travel.
Now you can quit imagining and are free to go back to the boring reality - nobody knows how the book captured at Fornovo looked like. It is lost for the history.
