Last week I spot in Amazon webshop  BBC Focus Magazine available for subscription and start trial period. Inside first issue I've found interesting article about latest attempt to decode mysterious Voynich manuscript.
The name of this manuscript comes from name of a Polish revolutionary, later British antiquarian and bibliophile Wilfrid M. Voynich. He found and bought this book on 1912 at the Villa Mondragone in Italy.
