I've found the author of Voynich manuscript. He was Giovanni Aurispa.

If the methodology you used works for the folios you translated, then it should work for at least much of the rest of the VM. Translate that and if it also makes sense, and matches any related images, then you might be onto something.

The method can be applied to the rest of the manuscript, producing results that make as much or little sense as what was posted here. As Tavie mentioned, it has been done with several different languages by several different people. Basically:

1) apply a quasi-simple substitution mapping Voynichese to the target alphabet;

2) hammer the result into relatively similar target-language words;

3) translate the resulting word salad by using a dictionary or Google translate, ignoring all grammar;

4) pretend it makes sense, make up something using the English words picked in step 3.

I discussed the method here: You are not allowed to view links. Register or Login to view.

Instead of translating pages and pages, it is more useful to discuss the details of the Latin grammar in the text. 

Checking word and bigram frequencies of the supposed Latin is also helpful and does not require knowledge of the language (e g. How many words end in -um or -us? How many occurrences of "et", the most frequent Latin word?). 

Another useful exercise is picking an actual Latin text and encoding it with the supposed cipher process: does the result show the typical features of Voynichese? (Spoiler: no, it doesn't)
