Ruby's Greek Thread

[Ruby Novacna]

I don't think it's possible to rule out Greek or any other language...
This is because we know that if it is language (and not meaningless gibberish), multiple things have been done to the text to give it the myriad un-language-like characteristics that it has, such as the entropy issue, the line patterns, etc.  

For the moment I am more interested in the identification of the language, than in the explanation of the value of entropy.
Moreover, if I understood the Wikipedia article correctly, the notion of entropy is quite recent, much later than our manuscript and the large number of coded letters. How did decoders proceed without calculating entropy?
