The Voynich Manuscript is often called 'the world's most mysterious book.' It is an illustrated codex hand-written in an unknown, undecipherable script. Carbon dating has placed the vellum to the early 15th century. The book contains hundreds of drawings of strange plants that don't exist, astronomical diagrams, and bathing scenes featuring small female figures. Despite the efforts of the world's top cryptographers, including British and American codebreakers from WWI and WWII, no one has ever successfully translated a single word. Some believe it is a sophisticated 15th-century hoax, while others think it is a lost language or an elaborate medical text written in cipher to avoid persecution. Its strange beauty and the literary puzzle it presents continue to inspire novelists and researchers alike.
