Post by Evertjan.Post by Ed CryerPost by David AmicusWhich is correct "Non Plus Ultra" or "Nec Plus Ultra"? I have seen both.
I've seen "Ne plus ultra".
<https://www.merriam-webster.com/dictionary/ne%20plus%20ultra>
However Latin "ultra" in French is "plus", not "ne ... plus".
<<It is said that the term's predecessor, non plus ultra, was inscribed on the Pillars of Hercules at the 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 1630s.>>
So originally it seems it was NON PLUS ULTRA
