In 1134, three brothers, knights from the French region of Laon, left on a voyage. The sultan of Egypt captured them and took them prisoner. Hoping at all costs to make them apostatize, he went so far as to send his remarkably beautiful daughter to seduce them. But while discussing the Gospel with the prisoners, believing she would defeat them, Ismenia was defeated. She asked the knights to carve the image of Mary for her. The knights prayed to the Blessed Virgin so that she would guide their hands. During the night, the Virgin sent angels bearing her radiant image of piety. The next day, when Ismenia returned the dungeon was filled with dazzling light and a delicious perfume exuded from the statue. The princess believed immediately and took the statue to her apartments, never taking her eyes off the statue while the knights cried out: Our Lady of Liesse! The following night, Ismenia heard the statue say: "Trust me, Ismenia! I have prayed to my Son for you. You will be his faithful servant. You will free my three beloved knights. You will be baptized and through you, France will be enriched by countless graces. Through you my name will become famous and later, I will receive you forever in paradise." Ismenia helped the prisoners escape and fled with them. All four of them were overtaken by a deep sleep, and during their sleep angels transported them to France. When they awoke, the three knights were in their country, near their castle in Marchais. Ismenia was baptized and they all agreed to have a chapel built at the site where they had woken up, in honor of Our Lady of Liesse. Since then miracles have been countless. Louis VII came as a pilgrim in 1146 and Our Lady of Liesse became a favorite pilgrimage destination of the kings of France.
