In all the round world of Utopia there is no meat. There used to be, but now we cannot stand the thought of slaughterhouses.
—H G Wells - A Modern Utopia
conceit
A fanciful poetic image or metaphor that likens one thing to something else that is seemingly very different. An example of a conceit can be found in Shakespeare's sonnet "Shall I compare thee to a summer's day?" and in Emily Dickinson's poem "There is no frigate like a book."
