Sir, only today the first time I ran into this mystery. So, I'm a new eye... I'm looking into the images provided for the Voynich Manuscript, and from the first glance it looks for me that it is indeed some Eastern European language written in Cyrillic alphabet. I was even able to read few words which make sense in Russian - Polish - or maybe Czech languages. Do you know if any research was done in that direction? (I mean Cyrillic alphabet + Eastern European language ?) . Still while trying to read some pages, I noticed unnatural repeating of some words, which is not natural in Eastern European languages, until it is some kind of song or poem. Or, can it be Latin language written in Cyrillic? The fact that I found some words which make sense in Russian, can be coincidence , but still worth looking...
