Simulacrum (noun): the appearance of religious imagery in natural phenomena - you know the sort of thing: the prophet Mohamed on a slice of toast; Christ on a banana skin.
The Blessed Virgin Mary has appeared in the following contexts recently:
a fence in Coogee, Australia
a hospital in Milton, Massachusetts
a felled tree in Passaic, New Jersey
a rock in Ghana
an underpass in Chicago,
a lump of firewood in Janesville, Wisconsin
a chocolate factory in Fountain Valley, California and
a pizza pan in Houston, Texas.
A grilled cheese sandwich, a pretzel and a pebble said to resemble images of the Virgin Mary have been offered for sale on internet auction sites.
Make sense of this who will.
