Alisa Gladyševa * *Faculty of Philology, Vilnius University, Vilnius, Lithuania. https://orcid.org/0000-0001-7739-1714 DOI: https://doi.org/10.55248/gengpi.5.0624.1511 A B S T R A C T Despite all the unsuccessful decipherment research methods that others have tried to apply, there was no solution in reading the Voynich manuscript. This research describes recent successful decoding methodology from the very doorway to deciphering the whole Voynich manuscript. In particular, the investigation of background information and detailed analytical studies of the characters of the Voynich manuscript, words that were written in plain way, which have been performed to define the algorithm of the encoded text. It gives emphasis on the importance of this research for its successful decipherment. Keywords: Voynich manuscript, MS 408, text decipherment, codicology, cipher. 1. Introduction Given the research embargo period on access to the book titled The deciphering the whole text of the Voynich manuscript by Al isa Gladyševa: the linguistic basis of the text, index, and analysis, isbn: 978-609-475-419-7, this research article represents one of the initial contributions in a series of open- access publications by the author, focusing on the Voynich manuscript, which she has already deciphered herself. The Voynich Manuscript, known as Yale University’s Beinecke Library Manuscript 408, remained undeciphered for centuries [1]. This research describes recent successful decoding approaches from the very doorway to deciphering the whole Voynich manuscript. Decipherment of the Voynich Manuscript is widely considered to be the most important achievement of the new innovative research. The Voynich Manuscript is an illustrated manuscript. The manuscript itself is bound in vellum, it was rebounded lately with the obvious loss of some folios. For this moment, it contains 116 folios, it means 232 pages. It was found by Wilfrid Voynich of Lithuanian origin, at the villa housed a former Jesuit library Villa Mondragone in 1911 or 1912. In 1969, the manuscript which bears Voynich name was donated to Yale’s Beinecke Library by H. P. Kraus. According to the results of innovative research of the Voynich manuscript was written in medieval Galician (Galician-Portuguese) (Gladyseva, 2019). The most important result in the encryption code of the Voynich manuscript that made decryption more complicated over the centuries was the use of specific cipher algorithm of polyalphabetic encryption that was used partially and simultaneously with monoalphabetic encryption (Gladyseva, 2020). The implementation of this specific cipher algorithm by the master of the Voynich manuscript resulted in the transformation of numerous words into plaintext, implying that they were effectively left unencrypted. The research results generating considerable interest in the very decipherment methodology itself. In particular, the doorway to investigation of background information and detailed analytical studies of the characters ‘l’, ‘a’, ‘v’, ‘n’, ‘d’ of the Voynic h manuscript, their decipherment, the reading and examination of vernacular plant names within the text, which contain these symbols. The results of analysis demonstrate that as a consequence of the particular cipher algorithm employed by the master, occasionally led these symbols to their conversion into plaintext characters. Introduction should be typed in Times New with font size 10. In this section highlight the importance of topic, making general statements about the topic and Presenting an overview on current research on the subject. The simplest way is to replace(copy-paste) the content with your own material. Your introduction should clearly identify the subject area of interest. 2. Methodology Some researchers focus solely on determining the language corresponding to the Voynich manuscript, yielding results that only rightly confirm the manuscript's human origin (R. Carbo-Dorca, 2021: 5). Robert Downing et al. (2020) accurately asserted in their article that the Voynich manuscript is composed in an Indo-European language (Downing et al., 2020). Others, such as Rugg and Taylor (2016), Daruka (2020), Timm and Shinner (2020)
