Previously on the Wikipedia page on the Voynich Manuscript:
In 1999, Antoine Casanova wrote and defended his doctoral dissertation on cryptanalysis of the Voynich Manuscript. In particular his work has highlighted the fact that the language used was structured. [1] (in French).
In 2017, in the bulletin ARCSI 2017 [2] (in French), he detected that what appeared to us to be Voynich's words were to be considered as propositions of words associating the Latin abbreviations and codes. He has decrypted the folio f116v.
In 2018, his effort has focused on the reconstruction of the coding table and on the modus operandi of the elaboration of the sentences in order to solve the Voynich’s enigma. He has decrypted sentences from the folio f66r and f80r.
