Paul Blackburn (1926–1971) was born in St. Albans, Vermont, the son of the poet and children’s book author Frances Frost. When he was fourteen he moved from Vermont to Greenwich Village, later spending a year at New York University before enlisting in the army. After his military service he transferred to the University of Wisconsin at Madison, where he studied Old Provençal and began a correspondence with Ezra Pound. Through Pound he became friends with Robert Creeley and was introduced to many in Creeley’s circle. In 1954 Blackburn received a Fulbright to study Provençal literature in the south of France and it was there he embarked on the project that would become Proensa. Back in New York, he continued to write and publish poetry while working various jobs, including printing-house clerk and encyclopedia-entry writer, and running a reading series that would become the legendary Poetry Project at St. Mark’s in the Bowery. He was known for encouraging the work of the young poets who later rose to prominence as members of the New York School and the Beats. By the mid-1960s, Blackburn had become recognized enough to take on traditional teaching jobs, and in 1967 received a Guggenheim Fellowship, which allowed him to live in Europe and concentrate on his own work. In all he published thirteen books of poetry and five translations, including works by El Cid, Pablo Picasso, Federico García Lorca, and Julio Cortázar. The final version of Proensa was published in 1978 seven years after Blackburn’s death from esophageal cancer.
