the first miracle happened when the Madonna on the fresco on the wall cried (tears were seen to have come out of her eyes, like in Medjugorie these days). The second miracle is that the tears didn't run straight down, but made a bend in order to avoid the figure of holy Jesus. The result is that, like the Berlin wall, they took a large chunk of wall out and placed it on the main altar! That is the fresco you see today on the altar, a humble Madonna sitting on the ground and breast-feeding baby Jesus. The "popolo" (ordinary folk) liked this picture because humble people could identify with humble Madonna.
