Leonardo da Vinci and the Voynich Manuscript

A number of the words in the manuscript appear to be repetitive so I assume that they are only there to confuse the reader and have nothing to do with the actual text. The remaining words may involve simple substitution of letters for example “cc” represents “on.” The first few words in s3724838 look like Feccccdo etc. but could be Fecondo ????? dama uretra. This is in accordance with the content of the drawing.
