For more than a hundred and fifty years the Miraculous Medal has been known and worn by Catholics throughout the world. It has been used and promoted by great saints and Popes as a most powerful sacramental. Less well known is the story of the French Sister to whom the Blessed Virgin manifested the Medal in 1830. This Vision Book for 9 - 16 year olds tells the story of Catherine LabourE, a Burgundy farm girl who, after a prophetic dream of St. Vincent de Paul, became a Sister of Charity in Paris and later in Enghien, where she cooked and mended and cared for the inmates of a home for elderly men. To this obscure Sister the Blessed Virgin appeared, made prophecies, and commissioned the making of the Medal which soon came to be known as ``miraculous`` because of the favors wrought. St. Catherine LabourE lived a life of prayer and service to the poor, and was canonized in 1947. Illustrated
