The Latin noun senex means an old man and senes is the plural: old men
They had no particulat title that I'm aware of. An old man was a senex. If he were a sensible old man he would be senex sapiens, a wise or prudent old man, he was senex prudens, if he were an experienced old man he would be senex peritus. Out of the three connotations, senex prudens would be the most fitting term for a wise old man.
Senex is singular in Latin and it means "old man" or "elder." The plural form is senes.
