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 Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
