[1] According to tradition while washing their clothes in the torrent, the women, with a blind and a deaf one among them,[2] saw the apparition of a woman with a child[2] and were hit by a gust of pebbles moved during the apparition,[2] but without getting any injury or pain;[3][4] on the contrary, after being hit by the pebbles, they strangely felt a certain sense of wellbeing[4] and recovered their health.
[5] Then the local authorities inquired on the spot, cut down the near grove[5] and found the ruins of a "cuba", an old arc of a mill that nobody remembered any longer,[5] and inside there was a fresco on a stone made by an anonymous painter of the 13th century representing Our Lady with the Child Jesus,[5][4][3] which at first the believers called "Madonna Fons Misericordiae" (that is Our Lady Source of Mercy).
[4] Further to these events, Don Fernando Vega, Alcamo's governor and justice captain,[4] ordered the construction of the Sanctuary of Our Lady of Miracles,[8] which hosts the Madonna's image.
Inside the Church there is a white marble sarcophagus containing the mortal remains of the governor Don Fernando Vega, according to his will.
The celebrations include: The traditional descent to the sanctuary is put on during the so-called "Historical Cortege" with period costumes.
