DELELOË, JEANNE DE SAINT-MATTHIEU. - Benedictine mystic, born in 1604 at Fauquembergues (diocese of Boulogne), she entered in 1620 the monastery of the Benedictine sisters of her native city. In 1635 she fled because of the disorders of war and settled with ten companions at Poperinghe (in Belgium), where she was prioress from 1637 and died on 13 April 1660.
Her soul purified by many sufferings, D. received lofty mystical graces, which, at the command of her spiritual director, she described in her autobiography (1646), in which she also relates her private revelations (Communications) that especially recommend devotion to the Sacred Heart of Jesus, as later propagated by St. Margaret Mary Alacoque.
