Achaemenes (/əˈkɛməniːz/) (born 705 BC) was the eponymous apical ancestor of the Achaemenid dynasty of rulers from Persis.Other than his role as apical ancestor, nothing is known of his life or actions. "It is quite possible that Achaemenes was only the mythical ancestor of the Persian royal house [, but] [i]f Achaemenes was a historical personage, he should have lived at the end of the 8th and the first quarter of the 7th century B.C."
