Roslyn M. Frank has also argued for notable similitudes between the Sardinian and Basque carnival traditions.
It's possible that the very word Sardinia and its related wanderwort sardine have a Vasconic origin. Basque: sarda: fish school, -in(a): suffix of making, action. If so, sardina means nothing but fish school component or fish that forms schools.
