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.
Library of Pergamum
Manuscripts were written on parchment, rolled, and then stored on the shelves. In fact, the word "parchment" itself is derived from Pergamum (via the Latin "pergamenum" and the French "parchemin"). Pergamum was a thriving center of parchment production during the Hellenistic period. The city so dominated the trade that a legend later arose indicating that parchment had been invented in Pergamon to replace the use of papyrus, which had become monopolized by the rival city of Alexandria. This however is a myth; parchment had been in use in Anatolia and elsewhere long before the rise of Pergamon. Parchment reduced the Roman Empire’s dependency on Egyptian papyrus and allowed for the increased dissemination of knowledge throughout Europe and Asia.
