Per’gamos (in Revised Version Pergamum) (height, elevation), a city of Mysia, about 3 miles to the north of the river Caicus, and 20 miles from its present mouth. It was the residence of a dynasty of Greek princes founded after the time of Alexander the Great, and usually called the Attalic dynasty, from its founder, Attalus. The sumptuousness of the Attalic princes had raised Pergamos to the rank of the first city in Asia as regards splendor. The city was noted for its vast library, containing 200,000 volumes. Here were splendid temples of Zeus or Jupiter, Athene, Apollo, and Æsculapius. One of “the seven churches of Asia” was in Pergamos. Rev. 1:11; 2:12-17. It is called “Satan’s seat” by John, which some suppose to refer to the worship of Æsculapius, from the serpent being his characteristic emblem. Others refer it to the persecutions of Christians, which was the work of Satan. The modern name of the city is Bergama.
