Simon Worrall, author of "The Poet and the Murderer" (about the Mark Hoffman forgeries) recently wrote an article for BBC News Magazine about the Voynich manuscript. Worrall notes that new theories about the manuscript "breed like mayflies." However, he confesses to believing that it's a modern forgery created by its discoverer, Wilfrid Voynich.
He writes: "One of the most common tropes in the history of forgery is that of a rare book dealer 'discovering' previously unknown manuscripts."
But even if you don't accept his theory, the article is worth a look because it has some nice photos of the manuscript itself. [BBC News
