The action of that person in antiquity would be expressed in the simple past. Any implications for the present might be expressed in the present perfect, however. The Greeks invented democracy, and the Western world has been trying to implement it ever since. Euclid proved that the number of primes is infinite. His methodology, called &#39;proof by contradiction&#39;, has been used by mathematicians throughout history. Nietzsche wrote hundreds of aphorisms. Many of them have been quoted by others.
