On the character of Wilfrid Voynich

[Jorge_Stolfi]

whether he was left- or right-handed [...] seems not relevant, really.

I agree.  This came up only because it was argued that he could not have forged the VMS or the letter because of the alleged disability on his right arm.

As for why he lied about the provenance of those books, those reasons you propose are quite plausible and sufficient.  But the why is mostly irrelevant to the BST (or the MFT).  The point is only that he had no scruples about lying about his sources.  

And now, it seems, also not about violating the Italian law, and acquiring Church property that the Church would probably not want to sell...

All the best, --stolfi
