An ancient city, formerly the metropolis of all Ionia, situated on the western coast of Asia Minor, on the confines of Caria, just south of the mouth of the river Meander. It was the parent of many colonies, and was celebrated for a temple and oracle of Apollo Didymaeus, an as the birthplace of Thales, Anaximander, Democritus, and other famous men.
The apostle Paul, on his voyage from Macedonia toward Jerusalem, spent a day or two here, and held an affecting interview with the Christian elders of Ephesus, who at his summons came nearly thirty miles from the north to meet him, Acts 20:15-38. He also revisited Miletus after his first imprisonment at Rome, 2 Timothy 4:20. There were Christians and bishops there from the fifth to the eighth century; but the city has long been in ruins, and its exact site can hardly be determined, so much is the coast altered around the mouth of the Meander.
