Unreadable by Arthur C. Penhaligon

The Voynich Manuscript has defeated the greatest codebreakers of the 20th century, including the team that cracked the Nazi Enigma machine. Resting in the Yale library, this small book, filled with illustrations of non-existent plants, naked nymphs, and astrological diagrams, is written in a flowing, elegant script that belongs to no known human language. Is it a medieval hoax, a lost language, or the notebook of a mad genius?

"Unreadable" takes the reader on a journey through six centuries of failure. From the court of Rudolph II in Prague to modern AI laboratories, everyone who has touched this book has been consumed by its riddle. The author explores the radiocarbon dating that places it in the early 15th century and dissects the leading theories: Is it a medical manual from the Aztecs? A Cathar prayer book? Or meaningless gibberish designed to fool an emperor? A gripping history of the world's most enduring intellectual locked room mystery.
