Pergamos. — Unlike Ephesus and Smyrna, Pergamos was not distinguished as a commercial city. Its importance was due to other causes. A striking coneshaped hill rose from the plain which bordered the northern banks of the Caicus. The hill was considered sacred. Its value as a strong natural fortress was early recognised, and it was used as a keep and treasury where local chieftains deposited their wealth. Its greatness as a city dated from Eumenes II., who was given by the Romans a large surrounding territory, and who fixed Pergamos as his royal residence. Under his auspices a splendid city — rich in public buildings, temples, art galleries, and with a library which rivalled that of Alexandria — rose into being. It has been described as a city of temples, “a sort of union of a pagan cathedral city, an university town, and a royal residence.” It retained its splendour even after it passed by bequest to the Roman Republic, and was declared by Pliny to be a city unrivalled in the province of Asia.
Sharp sword with two edges. — See Note on Revelation 1:16. The appropriateness of this language to the state of the church in Pergamos will best appear afterwards. (See Note on Revelation 2:15-16.)
