Metropolis of Pergamon
The Metropolis of Pergamon () was an ecclesiastical territory (diocese) of the Ecumenical Patriarchate of Constantinople in western Asia Minor, modern Turkey. Christianity in the city of Pergamon (modern Bergama), was introduced already from 1st century AD, while the local Christian community comprised one of the seven Churches of Asia mentioned at the Book of Revelation, written by John of Patmos. The bishopric of Pergamon was twice promoted to a metropolis: during the 13th–14th centuries, as well as for a short period in 1922. Today the "Metropolis of Pergamon and Adramyttium" is the see of a titular metropolitan.
Pergamon Altar
The structure is 35.64 metres wide and 33.4 metres deep; the front stairway alone is almost 20 metres wide. The base is decorated with a frieze in high relief showing the battle between the Giants and the Olympian gods known as the Gigantomachy. There is a second, smaller and less well-preserved high relief frieze on the inner court walls which surround the actual fire altar on the upper level of the structure at the top of the stairs. In a set of consecutive scenes, it depicts events from the life of Telephus, legendary founder of the city of Pergamon and son of the hero Heracles and Auge, one of Tegean king Aleus's daughters.
