Speculative fraud hypothesis

[ReneZ]

"Onomacritus (c. 530 - 480 BCE): This Greek compiler of oracles is considered one of the earliest known literary forgers. He created prophecies and attributed them to the poet Musaeus.

"Axiopistus (4th century BCE): He created forgeries attributed to the 5th-century BCE writer Epicharmus of Kos."

These are actually interesting examples. Both do not appear to have anything to do with 'sale for profit'. 
They bring me back to the point about terminology, and people will have different understandings of the words 'hoax' and 'fake'.

If 'just' the contents are deliberately not true, we should call it a hoax, but do we consider it a fake?
The above are not all that dissimilar from the Grimm fairy tales, but nobody would consider that a hoax or a fake. They were (probably) not intended to mislead.

(Using singular for typing and reading convenience.)
Anyway, these provide some examples of what the original Voynich MS creator may well have had in mind, which was the original point of this thread.
Suppose he wanted to show that he possessed an important book from ancient times, in an ancient language, and knew its contents. The parchment dating tells us nothing. He could have only used contemporary parchment and could have made it look old by making it look 'used'. If he wanted to.
Paper would have been a bad choice for such an old book.

While most people seem to agree that a hoax or fake at this time for sale at a profit is quite unlikely,
who knows, perhaps he even managed to sell it to someone. We just don't know anything about this.

However, the pros and especially cons that have been mentioned earlier on in this thread remain.

Another interesting possibility is not relatable to modern times, because now we know some things better than in the late Middle Ages.
In Isidore's Etymology, he teaches that the main known writing systems were invented by
specific persons:
- Hebrew was invented by Moses
- Syrian/Chaldaean was invented by Abraham
- Egyptian was invented by queen Isis, daughter of Inachos
- Greek was invented by Cadmos
- Roman was invented by the nymph Carmentis

This has led people in the past to try to 'get their name on this list'.
An example is a certain Aethicus. He has been mentioned here already I think. I don't remember too much about this story, but one can check online sources.

Our Voynich creator may have been such a person too, and this allows for all options:
- meaningful content by converting known texts to this writing
- meaningless content
- his own personal language, meaningful only for him
