Maria Gemma Umberta Pia Galgani (March 12, 1878 – April 11, 1903) was an Italian mystic, venerated as a saint in the Roman Catholic Church since 1940. She has been called the "Daughter of Passion" because of her profound imitation of the Passion of Christ. Gemma began to display signs of the stigmata on June 8, 1899, at the age of twenty-one. She stated that she had spoken with her guardian angel, Jesus, the Virgin Mary, and other saints—especially Gabriel of Our Lady of Sorrows.
