Patrice de La Tour du Pin (1911–1975) was born in Paris and raised in the Gâtinais. After a long imprisonment in Germany during World War II, he envisioned the three-part work for which he is known: Une somme de poésie. The first part confronts man’s relationship to himself; the second, his relation to the world; and the third, a relationship to God in which poetry becomes a form of prayer. Du Pin also worked on translating the Catholic Mass into the vernacular.
