[Blog Post] MSI at last!

[Scarecrow]

Marci wrote in his letter to Kircher that the previous owner (Barschius as we now know) spent years try to break the secrets of this MS, and Marci also sends Barschius' notes to Kircher.

So, if Marci knew of all these efforts, why would he consider that he could break it himself with a simple substitution cipher?  Of course, this is just double-guessing but it is a bit odd.
Then, perhaps, he was trying to preserve Barschius' last or best or most representative attempt in the MS itself?

I am more puzzled by this issue than by the third column.

I do not know if Marci knew Barschius, but if he did, it could explain because Barschius was not a not a renowed scholar, so whatever Braschius had done might not have been any real value for Marci. 

On the other had, as Marci wrote in he's letter to Kircher:
"This book bequeathed to me by an intimate friend, I destined for you, my very dear Athanasius, as soon as it came into my possession, for I was convinced it could be read by no one except yourself."

So if Marci was convinced that only Kircher could be capable of reading the MS, as soon as he saw it, it is quite natural that he wouldn't have had much interest to dedicate more effort for it. He might have just played with it for a while for excercise of intelligence and curosity, nothing much more. It quite probable that he had many more matters in he's hands and now MS was not his but Kircher's problem.
