Ave sanctissima Maria: This prayer, for which Pope Sixtus IV is said to have granted an indulgence of 11,000 years (!) when prayed before an image of the Virgin in the Sun, can be found in many manuscripts since the 1470s.: Hail most holy Mary, mother of God, queen of heaven, gate of paradise, ruler of the world. You are a uniquely pure virgin. You conceived Jesus without sin. You bore the creator and saviour of the world in whom I do not doubt.
