View of the 4th century BC monument of the Eponymous Heroes in the Agora. On the 16 metre long narrow base once stood ten bronze statues of legendary heroes chosen by the Delphic Oracle as founders of the ten tribes of Attica. New laws and official announcements were made public here in ancient times. The Agora from 600 BC onwards was the commercial and social centre of Ancient Athens. It was here that laws were written and displayed, commercial goods bought and sold, intellectual discussions were had, and the democratic spirited was born and nurtured.
