Concise Bible Dictionary:

(myrrh). A coast city of Ionia, Asia Minor, 40 miles north of Ephesus. Mentioned in Revelation 2:8-11 as site of one of the seven churches of Asia. The old city of Smyrna dates back to Theseus, 1300 years B. C. Alexander the Great built the new city B. C. 320. It became subject to Rome and was noted for its beauty. Christianity got an early foothold there and the city sent a bishop to the council of Nice, A. D. 325. It is still a large city of mixed nationalities and creeds, and of considerable commercial importance.
