One of Champaigne's most accomplished works, it is a votive offering (an ex-voto) by the painter which depicts a miracle involving his daughter that is said to have occurred at the Port-Royal-des-Champs Cistercian convent.

After the Mother-Superior's novena, Sister Catherine soon attempted to walk, and found herself increasingly mobile; the illness no longer seemed present.

[1] Their refusal to sign a document condemning five propositions found in Jansen's Augustinus resulted in their being deprived of the sacraments and confined to the abbey, which was eventually torn down.

His decision to portray the moment that Mother-Superior Agnès is instilled with hope, rather than the cure itself, is evident in the fact that the ray of light illuminates her instead of his daughter.

The inscription, addressed to Christ, recounts that Sister Catherine suffered for 14 months from a high fever and that half her body was paralyzed; that she prayed with Mother Agnès and her health was restored, and again she offered herself to Christ; and that Champaigne offers the painting as a testament to this miracle and to express his joy.
