Maurice Périsset’s *La vie extraordinaire du curé d’Ars* offers a vivid portrait of Saint Jean‑Baptiste‑Marie Vianney, the 19th‑century parish priest of Ars whose humble devotion transformed a remote French village into a center of pilgrimage. Drawing on parish records, contemporary testimonies, and the saint’s own writings, the biography traces Vianney’s early struggles, his relentless dedication to confession, and the spiritual renewal he inspired among the faithful. Périsset balances factual detail with narrative flair, allowing readers to feel the quiet intensity of the curé’s daily routine while appreciating the broader social and religious currents of post‑Revolutionary France. The work situates Vianney’s legacy within the Catholic tradition, highlighting his influence on modern pastoral practice and his enduring status as a model of self‑sacrificial service.
