The "Vie de Rancé" is a hagiographic work by François-René de Chateaubriand that tells the life of Armand Jean Le Bouthillier de Rancé, the founder of the reformed Cistercian monastery of La Trappe. Rancé was born into a noble family in 1626 and initially lived a worldly life, pursuing a career in the church and becoming involved in political intrigues. However, after a profound spiritual experience, he renounced his former life and entered the monastery of La Trappe, where he implemented strict reforms and became known for his austere lifestyle and devotion to prayer. Chateaubriand's biography provides insights into Rancé's character and the religious and social context of his time, exploring themes such as the nature of grace, the role of suffering, and the importance of humility.
