Samuel Taylor Coleridge wrote, in Biographia Literaria (1817), ch. 22: "In poetry, in which every line, every phrase, may pass the ordeal of deliberation and deliberate choice, it is possible, and barely possible, to attain that ultimatum which I have ventured to propose as the infallible test of a blameless style; namely: its untranslatableness in words of the same language without injury to the meaning."
