She entered the monastery of St Cecilia at Solesmes in 1866 and became its Abbess in 1870, bringing it to remarkable flourishing. The French persecution of 1901 forced her into exile on the Isle of Wight.
She gained considerable renown for her work *La vie spirituelle et l'oraison d'après la Ste Écriture et la tradition monastique*, published in 1899 and reprinted several times thereafter; it was translated into German, English, and Dutch. The author grounds holiness in prayer, both liturgical and private, offering practical advice that makes her writing useful not only to contemplative souls, for whom it was intended, but also to Christians living an active life. Less well known is her *Commentaire du Cantique des cantiques*, Worcester (Stanbrook Abbey) 1913.
