That's my blog: I've been documenting Edith Sherwood's amazing (but wobbly) Voynich claims for the last few years, such as:-
(1)
That a very young Leonardo da Vinci wrote it
Problem: LdV was left-handed, while the Voynich Ms was written by a right-hander. D'oh!

(2)
That she has managed to decode the Voynich plants
Problem: her botany and history both seem thin (if not actually transparent). Duh!

(3)
That the VMs is anagrammed, as evidenced by the unreadable marginalia on the back page
Problem: this is just optimistic rubbish, based on her reading of the third letter. Drat! See the above link as well as:-

Honestly, why does she keep posting up this stuff? And (perhaps more interestingly) why does she keep promoting it via Google Adwords? Given that she must have spent thousands of dollars by now, perhaps she's planning to write an amazing "The-Voynich-was-by-Leonardo" book? All nonsensical grist for the long-suffering Voynich mill, I'm afraid.
