"[1] André Breton, fascinated by the darkness and imagery in Duprey's poetry, invited the author to Paris in 1948.
Duprey's books are not a celebration of death, neither do they find comfort in thinking about it.
All questions asked in the poems of his last book The End and the Means (1970) are left unanswered, but their author found a way somewhere "beyond" (Jouffroy, 1970, quoted in [1]).
One day he went to the grave of the Unknown Soldier by the Arc de Triomphe and urinated on the eternal flame [2] for which he was arrested and beaten in the jail; later also taken to a mental hospital.
He wrote his final book in 1959 and upon completion, he asked his wife to send the manuscript to Breton.
