Someone claims to have decoded the indecipherable Voynich manuscript – and it’s a women’s health manual! Now, it’s probably not true, but it’s a fun read.
To the uninitiated: the Voynich manuscript is one of those long-standing historian mysteries. People were unsure where it came from, how old it was, and most of all, what the weird writing in it actually meant. For years and years, people have tried to decode what’s in it, and come up blank.
This sort of “omg they’ve cracked it!” story pops up every couple years — see this MetaFilter thread for examples. The most well-sourced theory is that the manuscript is actually Nahuatl.
