Massimo Pittau (1921-2019) was a renowned Italian philologist. Born in Sardinia he has written extensively about his native land. Unfortunately, his work is only available in Italian, however, Google Translate will help the linguistically challenged, such as myself.
One paper, with a link to the English translation below(a) , had valuable comments to offer about the content of Homer’s Odyssey as well as some interesting theories on the origins of the Sardinian Nuragic people. He traces them back to Lydia, now in northwest Turkey and its capital, Sardis.
