OK, but what exactly does that prove?
That modern Macedonian language dates back at least to that time.
Which contradicts Bulgarian and Greek claims, that Macedonians speak Bulgarian.
OK, but what exactly does that prove?
There's a Greek idea that it was a recent copying of Greek heritage.
I'd say that Greece is far more an effort by Greek elites to recreate the Classical world that they had learned about in their childhood - in the early days it was extremely Classicising without any input from foreigners. The first government tried to ban demotic Greek from parliament and hoped to introduce the Attic of Demosthenes as the national language, I mean.
While that's admittedly an extreme example, I think every nation-state has done this to some degree. Every nation-state created in the 19th and 20th centuries had as many differences as similarities. To overcome this, they reached to the past (often a fictitious past) and played up their past heritage. The playing up of the Irish language (and establishment of Gaeltachts) is one example. The use of the Hebrew language and making Jerusalem (as opposed to Tel Aviv) the capital of Israel is another. Conquering Rome from the Papacy and using the Florentine dialect (Dante, Petrarch, Machiavelli, Boccaccio, etc.) for a unified Italy is another example. Germany always seemed a little more Prussian than some of the others (possibly complicated by the need to exclude Austria from the "German" heritage), but I'm sure someone with more knowledge can point to something there. Greece is hardly unique there. In fact, of all the examples I've listed, I think Israel has quite a few similarities.
