Gertrude the Great

Gertrude of Helfta, also known as Gertrude the Great, was a German Benedictine Cistercian nun and mystic of the 13th century. Admitted to the Helfta monastery, a center of female mysticism, at a very young age (around 5), she received a comprehensive education there. Initially devoted to secular literary and theological studies, she underwent a profound spiritual conversion in 1281. From then on, she dedicated herself entirely to contemplative life, prayer, and mystical experience. Her visions and revelations of the Sacred Heart of Jesus, which she documented in her major work, 'The Herald of Divine Love' (Legatus divinæ pietatis), make her one of the key figures in the devotion to the Sacred Heart and Rhenish mysticism. Her writings are characterized by deep spirituality, rich theology, and poetic language, influencing many mystics and theologians after her. She was implicitly canonized by Benedict XIV in 1740, and her feast day is celebrated on November 16.
