Ingratitude, thou marble-hearted fiend,
More hideous when thou show’st thee in a child
Than the sea-monster!
– William Shakespeare
King Lear, Act 1, Scene 4. Lear flies into a rage when daughter Goneril complaints about the conduct of Lear’s 100 knights and asks him to reduce their number, keeping only what he needs. Using a metaphor he curses the cold-hearted devil, ingratitude, saying it is more hideous than a sea monster when it appears in a child. Daddy and daughter are not happy living under the one roof.
