Pergamos
    the chief city of Mysia, in Asia Minor. One of the "seven
    churches" was planted here (Rev. 1:11; 2:17). It was noted for
    its wickedness, insomuch that our Lord says "Satan's seat" was
    there. The church of Pergamos was rebuked for swerving from the
    truth and embracing the doctrines of Balaam and the
    Nicolaitanes. Antipas, Christ's "faithful martyr," here sealed
    his testimony with his blood.
      This city stood on the banks of the river Caicus, about 20
    miles from the sea. It is now called Bergama, and has a
    population of some twenty thousand, of whom about two thousand
    profess to be Christians. Parchment (q.v.) was first made here,
    and was called by the Greeks pergamene, from the name of the
    city.
