Claims about supernatural phenomena, including weeping statues, have historically been common in Catholicism. A well-known example is the Madonna of Syracuse, Sicily, a plaster statue that has shed tears since 1953. Last year, in fact, weeping statues were reported in Hungary, Argentina and Macedonia, just to name a few.

To understand why a weeping statue would be religiously meaningful, it's first important to appreciate the connection between miracles and the Virgin Mary.
