The vowel exchange "a" to "o"

[Petrasti]

Hi ReneZ, it`s strange that after so much time nobody could decipher the language, but I find it just as strange too, that it could not be deciphered with today's technology. Although I still hope for a language from the grammatically recurring system. if it is an encoded Hebrew or Arabian, then Stolfi system with prefix-unfix-suffix would be a possible structure.
