Marie Martha Chambon (March 6, 1841 - March 21, 1907) was a nun of the Religious of the Visitation of Chambery, known for introducing the Rosary of the Holy Wounds. She began to report visions of Jesus in 1866, telling her to contemplate the Holy Wounds. These were visions of Jesus Christ appearing to her and teaching her specific prayers and meditations on His wounds. She reported that she was told to pray to and invoke the Holy Wounds unceasingly.

Her mother superior kept a chronicle of her life which constitutes this book, here translated from the original French and re-published again for the first time in 93 years.
