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.
Parchment
The word parchment evolved (via the Latin "pergamenum" and the French "parchemin") from the name of the city of Pergamon which was a thriving center of parchment production during the Hellenistic period. The city so dominated the trade that a legend later arose which said that parchment had been invented in Pergamon to replace the use of papyrus which had become monopolized by the rival city of Alexandria. This account, originating in the writings of Pliny the Elder ("Natural History", Book XII, 69–70), is dubious because parchment had been in use in Anatolia and elsewhere long before the rise of Pergamon.
