The article contains the following sentence:
Italian linguist Vittore Pisani stated: "The Macedonian language is actually an artefact produced for primarily political reasons"
After the quotation mark, there is footnote 13, which refers us to an article in Word format. I opened the article and there doesn't seem to be any mention at all of Vittore Pisani, or of artefacts. Apparently, this is a misquotation, unless I missed something.
