The impression I have of Fontana is he was showcasing his skills.

Maybe the author of the Voynich was doing the same thing.

Often motivations in life are complicated. There can be a mixture of different motivations. The reason that one person does one thing may be difficult for another person to understand. An individual may not even understand their own motivations.

There are a lot of things that people did in the past that seem very odd and hard to understand from a modern perspective. To reiterate I think it is mistaken to view motives as purely rational and functional. Why do we post on this forum?
