Look elsewhere if you want to find answers (however impossible to prove) - only questions here.
I know this has been marginally discussed here, way before my time on ATS, but the discussion is scattered in various threads - most of them including
my
bete noire (or should I say
brune?

), Dan Brown...
Personally, I think it would be a good idea to gather as many opinions as possible within a single thread.
(If possible, without involving Mr. Brown. It really isn't necessary: it's not like he knew anything about Leonardo - starting by his name...

)
Many people - and that, amazingly, includes art historians - still to this day perpetuate the silly notion that thereby he wanted to "hide" his
notes from the public.
For sure, Leonardo liked his cloak of mystery, he created it himself and did everything in his power to enhance it. But I don't think he would have
been stupid enough to think that nobody who could read would crack his mighty mirror "code" in less than a minute.
Or would he have been as asinine as that?
(After all, one should never underestimate the limitations of a narcissistic mind. :-))
Personally, I don't think so.
He may have discovered - by intuition - that using both hands promotes the optimal functioning of the brain, and wrote like that - or even using both
hands simultaneously (it's fun, try it sometimes, if you haven't so far!) - just for practice.
But would he have written entire notebooks like that?
Or maybe he did it just for plain, sheer - fun?
To tease posterity, perhaps?
That would certainly have been in character... But WAS it so?
Obviously, it's impossible to prove it.
Still, any relevant thoughts would be welcome.
