[4] Biagio Marin was born on 29 June 1891 in the coastal town of Grado, in what was then the Austro-Hungarian county of Gorizia and Gradisca.

There he read Russian and Scandinavian authors and met the Austrian educator Friedrich Wilhelm Foerster,[10] who had great influence upon his subsequent choices of study and work.

He graduated in philosophy under Bernardino Varisco, the fascistic philosopher Giovanni Gentile whose idealistic doctrine had already exerted a profound influence on him, and was the chairman of the committee.

Marin landed a position as Professor at the Scuola Magistrale in Görz, but had to leave following a dispute about his teaching method with the clergy at the school.

His eyesight deteriorated, and for the rest of his life he was nearly blind and deaf [18][19] After his death his private library was moved to the Biblioteca Civica in Grado.

[21] His son Falco Marin was a poet and essayist, who died during World War Two in a fight against the Yugoslav partisans in the Province of Ljubljana, Slovenia on 25 July 1943.

[25] Immediately after the death of his friend, Pier Paolo Pasolini, Marin composed a Cycle of poems called "El critoleo del corpo fracasao" about him.

[26] Marin's poems, written in the Venetian language, are about the daily life and simple landscapes of his native land.

Andrea Zanzotto and Pier Paolo Pasolini had some difficulties with the existence of religious thematics in Marin's work.

[28] In 1970, the poet decided to publish all the poems written at that time in one volume, which, apropos to his sentimental attachment to his land, was titled "Songs from the Island."

[32] He was active for many years as president of the "Circolo di cultura italo-austriaco" in Trieste, and he was among the first leaders of the "Incontri Culturali Mitteleuropei" in Gorizia.

For Pier Paolo Pasolini, Marin's poems were the greatest Italian verses written in a contemporary dialect.
