Nullumst iam dictum quod non sit dictum prius.
"Nothing is said now that has not been said before."
(nullumst is a fairly common contraction of nullum est - often words ending in -Vm before est become contracted to -Vmst in colloquial Latin)
~ Publius Terentius Afer, c. 195/185 - c. 159 B.C.E. (playwright commonly called "Terence" in English)
