It is the height, the zenith, the ultimate, the crown, the pinnacle. It is the peak, the summit, the crest, the high-water mark. All these expressions, of course, mean "the highest point attainable." But ne plus ultra may top them all when it comes to expressing in a sophisticated way that something is the [pink](https://www.merriam-webster.com/dictionary/pink) of perfection. It is said that the term's predecessor, non plus ultra, was inscribed on the [Pillars of Heracles](https://www.britannica.com/place/Pillars-of-Heracles) at the [Strait of Gibraltar](https://www.britannica.com/place/Strait-of-Gibraltar), which marked the western end of the classical world. The phrase served as a warning: "(Let there) not (be) more (sailing) beyond." The New Latin version ne plus ultra, meaning "(go) no more beyond," found its way into English in the early 1600s.
