The Areopagus is a prominent rock outcropping located northwest of the Acropolis. In pre-classical times (before the 5th century BC), the Areopagus was the council of elders of the city, similar to the Roman Senate. Like the Senate, its membership was restricted to those who had held high public office, in this case that of Archon. 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 462 BC, Ephialtes put through reforms which deprived the Areopagus of almost all its functions except that of a murder tribunal in favour of Heliaia.
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).
Phryne, the hetaera from 4th century BC Greece and famed for her beauty, appeared before the Areopagus accused of profaning the Eleusinian mysteries. One story has her letting her cloak drop, so impressing the judges with her almost divine form that she was summarily acquitted.
In an unusual development, the Areopagus acquired a new function in the 4th century BC, investigating corruption, although conviction powers remained with the Ecclesia.
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.
References:The Broch of Clickimin is a large and well preserved, though somewhat restored broch near Lerwick. Originally built on an island in Clickimin Loch (now increased in size by silting and drainage), it was approached by a stone causeway. The water-level in the loch was reduced in 1874, leaving the broch high and dry. The broch is situated within a walled enclosure and, unusually for brochs, features a large 'blockhouse' between the opening in the enclosure and the broch itself. Another unusual feature is a stone slab featuring sculptured footprints, located in the causeway which approached the site. Situated across the loch is the Clickimin Leisure Centre.
