The Voynich manuscript, once owned by Emperor Rudolph II in 16th-century Bohemia, is filled with drawings of fantastic plants, zodiacal symbols and naked ladies. Far more intriguing than its illustrations, however, is the accompanying text: 234 pages of beautifully formed, yet completely unintelligible script. Modern scholars have pored over the book since 1912, when Wilfrid Voynich, an American antiquarian, bought the manuscript and started circulating copies in the hope of having it translated. Some 90 years later, the book still defies deciphering.” Now a computer scientist thinks he might have an answer.
