The apparition was reported by Giovannette, daughter of Pietr Vaccli and wife of Francesco Varoli. She said that on May 26, 1432, Mary appeared in a field in Caravaggio, in Northern Italy, in the region of Milan; and said that her son was angry, that for him people should fast on Fridays and for her they should celebrate Saturdays after vespers. Our Lady announced peace to Giovannette in her family, among the neighboring warring states and reconciliation between the Church in the East and West, through the Council of Florence (1436-1445). As memento of her presence she left the imprint of her feet on the stone where she stood. A spring of water sprung forth from under the stone.
