This is the story that seems to have inspired an anonymous author of a very famous satirical poem in Sardinia, the "Sa scomuniga de Predi Antiogu, arrondas de Masuddas", which seems to have been written around 1850 and was first published by the Typography of Corriere di Sardegna in Cagliari over 100 years later. It is a poetic excommunication where only the "official" excommunication part was written using the Latin formulas.
This curious script fascinated several famous persons, including Antonio Gramsci, who, judging the poem "fresh and humorous", urged his mom to send him a copy in prison in a letter from 1927, and Max Leopold Wagner, author of fundamental studies about culture and language of Sardinia, which translated "Sa Scomuniga" into German and published the masterpiece in Germany in 1942. Wagner said about this poem: he has no literary pretensions, but he does not lack "comic vis", precisely because he also reflects the primitive mentality and a language full of nasalizations, transpositions of sounds and disagreements of country side people.
Subsequently, other editions of the poem were published and summarized in the brilliant and thorough work of Antonello Satta published in 1983.
Also recently, the poem inspired Elio Turno Arthemalle and Rossella Faa (photo) to create a theatrical representation called "Predi Antiogu and Perpetua", of which we propose the following clip realized by Buongiorno Regione (RAI).
The German version of Max Leopold Wagner favored the dissemination of this peculiar poem to scholars and universities all over the world.
