Voynich through Phonetic Irish

[Jorge_Stolfi]

If a person was to find 240 pages of modern communication in English, they probably would be able to figure it out.

That is not true, unless the language of those future archaeologists is reasonably close to English.  Check how hard it has been to decipher dead languages like Egyptian hieroglyphics, cuneiform, Etruscan, Hittite, Linear A, Mayan hieroglyphics... Progress in those languages only started when "Rosetta Stones" were found.  

Even in Hittite the key was a sentence with one known Sumerian hieroglyph meaning "bread",followed by the guess that it was Indo-European and then by the guess that other words had to do with eating and drinking.

All the best, --stolfi
