On August 18, 1996 in Buenos Aires, Argentina, at Holy mass, a woman discovered a discarded host on a candleholder and brought it to Fr. Alejandro Pezet who placed it in a container of water inside the tabernacle of the chapel of the Blessed Sacrament. The following Monday, August 26, upon opening the tabernacle, the priest was astonished to find that the Host had become a bloody substance and he notified his Bishop Jorge Bergoglio (now Pope Francis I), who gave instructions that the bloodied flesh be photographed. When the photographs were taken on September 6, the bloodied flesh had grown significantly in size. After it had been kept in the tabernacle for a few years the Bishop decided to have it scientifically analyzed since it had not suffered any visible decomposition. . .
