The name comes from a Polish antique book dealer called Wilfrid Voynich, who bought the manuscript in Italy back in 1912. Take a look inside and you'll find botanical and astronomical ink drawings and text written in a strange language (or a so far undeciphered code), iflscience.com wrote.
Over the years, linguists, mathematicians, and World War Two cryptologists have studied the manuscript, but while there have been several theories, no one has been able to decipher the language or work out what the book was for. Many believe it's a hoax and think the text is meaningless. Some other theories are a little more out there. One says it's a document written by an alien stranded on Earth. Another claims it's a guide to alchemy.
Now, historian Nicholas Gibbs says he's found the answer and it's brilliantly mundane. He thinks the Voynich manuscript is a ladies' health manual.
Writing in the Times Literary Supplement, Gibbs first compares the manuscript to other Medieval texts concerning women's health. Aside from the pictures of plants and zodiac signs, there are drawings of women as well.
Next, he explains the unusual writing in the manuscript, which contains "tell-tale signs" of an abbreviated Latin format. From this, he determines that each character is, in fact, an abbreviated word – not a letter.
He then puts forward the crux of his theory: The manuscript contains a series of recipes for women’s health and other gynecology-related medicines.
