A bit of Greek mythology.
"Niobe, queen of Thebes, once boasted that she was better than Leto because she had many children while the goddess had but two. Artemis and Apollo avenged this insult to their mother by killing all or most of Niobe's children with their arrows. The weeping Niobe was transformed into stone, in which form she continued to weep."
and another quote
"A devastated Niobe fled back to Mount Sipylus and was turned into stone, and, as she wept unceasingly, waters started to pour from her petrified complexion."
