A Sacred Heart with an enclosed space for a photo or relic. Devotion to the Sacred Heart of Jesus began in 17th century Paris when a nun, Margaret Mary Alacoque (1647-1690), had a vision of Christ. The vision urged her to dedicate herself to the heart of Christ, a symbol of his love for mankind. The sacred heart came to be a prominent symbol, by itself and placed on crosses, usually along with various instruments of passion. The image is also associated with the Franco government in Spain, where the Loyalists destroyed the image due to its identification with the Nationlist forces. In France, the image was identified with the Thiers government and the suppression of the Paris commune. At the centennial anniversary of the commune in 1971, tomatoes and rocks were thrown at the Sacred Coeur Cathedral in memory of the suppression. Separately, a similar devotion to the Immaculate Heart of Mary, promoted by John Etudes (1601-1680), emerged around the same time as Alacoque, based on the Seven Sorrows of Mary, resulting in an image of seven swords and her heart or a heart pierced by a sword.
