The Scapular of the Sacred Heart is a Roman Catholic devotional scapular bearing an image of the Sacred Heart of Jesus on the front panel, and an image of the Virgin Mary as Mother of Mercy on the panel which hangs at the wearer's back. In its current form, the design and the formal church approval for its use are due to Estelle Faguette, a French domestic servant, who in 1876 claimed to have received a series of apparitions during which the Virgin Mary showed this scapular and spoke about its use.
Prior to Faguette's 1876 claims, devotion to the Sacred Heart of Jesus had been made popular by the 17th Century mystic, Margaret Mary Alacoque who herself made and distributed 'badges' bearing images of the Sacred Heart of Jesus.
