The Fourth Apparition
The last apparition of St. Michael was in answer to prayer as the terrible plague of 1656 had hit the area. The local bishop with his people invoked the Archangel and the plague ceased. It was at this time that the use of stone chips from the cave began to be used by the faithful much as medals or scapulars are used today. This custom is carried on even now by the local people who take small stones and place them around their homes and in the fields.
