"Ermesinde" by Theodor Zenner is a historical novel written in the early 20th century. It follows the life of Ermesinde of Luxembourg from her celebrated baptism through courtly splendor, personal tragedy, and a deepening spiritual vocation, blending feudal intrigue with Catholic devotion and legend. The central figures include Ermesinde, her parents Count Heinrich (later called “the Blind”) and Agnes, and her husband Theobald of Bar, with the narrative moving toward the envisioned founding of a Cistercian convent at Clairefontaine.

The opening of the book moves from Ermesinde’s festive christening in Luxembourg to a grand hunt at Bardenburg, where a misfired arrow from her mother Agnes grievously wounds Count Heinrich, leading to his blindness and lifelong sorrow. Agnes declines and dies, and Heinrich—harried by rivals and misfortune—eventually passes away, leaving Ermesinde orphaned. Raised under the gentle guidance of Kunigunde of Schockweiler, Ermesinde comes of age amid renewed courtly gaiety and marries the warlike Theobald of Bar, whose quarrelsome campaigns bring excommunication, penance, and a distant crusade. After Ermesinde’s own pilgrimage, news ceases; Theobald’s body is finally borne home, plunging her into desolation and seclusion at Bardenburg. In this despair she experiences a Marian apparition at the “clear spring,” with the Child Jesus and white sheep marked by a black scapular—an image pointing to Cistercian nuns. Seeking counsel from the hermit Rhabanus and hearing of St. Bernard’s blessing of the spring, she resolves to establish a convent at Clairefontaine, even as she is counseled that her duty still lies upon the throne.
