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
The first mention of Pergamon after ancient times comes from the 13th century. Beginning with Ciriaco de' Pizzicolli in the 15th century, ever more travellers visited the place and published their accounts of it. The key description is that of Thomas Smith, who visited the Levant in 1668 and transmitted a detailed description of Pergamon, which the great 17th century travellers Jacob Spon and George Wheler were able to add nothing significant to in their own accounts.
