When Ga-in is scanning the wall of the old man's home with the newspaper clippings and pictures, she reads a headline that says: "Argument with wife, father kills all four children." The bug-eyed image to the right of this is Goya's painting "Cronus Devouring One Of His Sons"; Greco-Roman mythology states that the titan Cronos/Saturn was told one of his sons would overthrow him as he overthrew his own father, so to prevent this, he devoured them all - reflecting the movie's theme of envy-provoked murders.
