The Marian Apparition in Paris.  Catherine Laboure was 24 when Mary first contacted her.  Mary warned her of the oncoming troubles. A week later those troubles came true, that being the revolution starting in Paris just a week later.  Later that year, Mary appeared before Catherine again and asked her to place a medal where they worshipped her.  Mary told Catherine it would be a source of great graces and should be worn around the neck.
