Areopagus

 
The Areopagus or Areios Pagos (Greek: Ἄρειος Πάγος) is the "Rock of Ares", north-west of the Acropolis, which in classical times functioned as the high Court of Appeal for criminal and civil cases in Athens. Ares was supposed to have been tried here by the gods for the murder of Poseidon's son Alirrothios (a typical example of an aetiological myth).
The origin of its name is not clear. In Greek pagos means big piece of rock. Areios could have come from Ares or from the Erinyes, as on its foot was erected a temple dedicated to the Erinyes where murderers used to find shelter so as not to face the consequences of their actions.
In 594 BC, the Areopagus agreed to hand over its functions to Solon for reform. He instituted democratic reforms, reconstituted its membership and returned control to the organization.
In The Eumenides of Aeschylus (458 BC), the Areopagus is the site of the trial of Orestes for killing his mother (Clytemnestra) and her lover (Aegisthus).
The Areopagus, like most city-state institutions, continued to function in Roman times, and it was from this location, drawing from the potential significance of the Athenian altar to the Unknown God, that the Apostle Paul is said to have delivered the famous speech, "Now what you worship as something unknown I am going to proclaim to you. The God who made the world and everything in it is the Lord of heaven and earth and does not live in temples built by hands." ( Acts 17:24)
The term "Areopagus" also refers to the judicial body of aristocratic origin that subsequently formed the higher court of modern Greece.
