thi-a-ti'-ra (Thuateira): Thyatira was a wealthy town in the northern part of Lydia of the Roman province of Asia, on the river Lycus. It stood so near to the borders of Mysia, that some of the early writers have regarded it as belonging to that country. Its early history is not well known, for until it was refounded by Seleucus Nicator (301-281 B.C.) it was a small, insignificant town. It stood on none of the Greek trade routes, but upon the lesser road between Pergamos and Sardis, and derived its wealth from the Lycus valley in which it rapidly became a commercial center, but never a metropolis. The name "Thyatira" means "the castle of Thya." Other names which it has borne are Pelopia and Semiramis. Before the time of Nicator the place was regarded as a holy city, for there stood the temple of the ancient Lydian sun-god, Tyrimnos; about it games were held in his honor. Upon the early coins of Thyatira this Asiatic god is represented as a horseman, bearing a double-headed battle-ax, similar to those represented on the sculptures of the Hittites. A goddess associated with him was Boreatene, a deity of less importance. Another temple at Thyatira was dedicated to Sambethe, and at this shrine was a prophetess, by some supposed to represent the Jezebel of Revelation 2:20, who uttered the sayings which this deity would impart to the worshippers.
