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.
