This "urtext" or "scholarly" (scientific) edition is in the public domain because it was published at least 25 years ago for most of the EU (20 years ago in Italy, 30 years ago in Poland) over 25 years ago for the former USSR. Such editions are also public domain in Canada because they fail to meet the minimum 'threshold of originality' to qualify for copyright as an 'adaptation'. They may not be public domain elsewhere.
