The Monument of the Eponymous Heroes, located in the Ancient Agora of Athens, Greece and adjacently situated near the Metroon (old Bouleuterion), was a marble podium that bore the bronze statues of the ten heroes representing the tribes of Athens. Being an important information center for the ancient Athenians, it was used as a monument where proposed legislation, decrees and announcements were posted.
Names of the ten heroes: Erechtheus, Aegeus (Theseus' father), Pandion (usually assumed to be one of the two legendary kings of Athens, Pandion I or Pandion II), Leos, Acamas (son of Theseus), Oeneus, Cecrops II, Hippothoon, Aias (Ajax), Antiochus (a son of Heracles).
