Magnesia on the Maeander [SEP] Introduction
Magnesia or Magnesia on the Maeander ( or ; ) was an ancient Greek city in Ionia, considerable in size, at an important location commercially and strategically in the triangle of Priene, Ephesus and Tralles. The city was named Magnesia, after the Magnetes from Thessaly who settled the area along with some Cretans. It was later called "on the Meander" to distinguish it from the nearby Lydian city Magnesia ad Sipylum. It was earlier the site of Leucophrys mentioned by several ancient writers. The territory around Magnesia was extremely fertile, and produced excellent wine, figs, and cucumbers. It was built on the slope of Mount Thorax, on the banks of the small river Lethacus, a tributary of the Maeander river upstream from Ephesus.
