Magnesia ad Sipylum (modern Manisa, Turkey), was a city of Lydia, situated about 65 km northeast of Smyrna (now İzmir) on the river Hermus (now Gediz) at the foot of Mount Sipylus. The city should not be confused with its older neighbor, Magnesia on the Maeander, both founded by colonists from the Greek region of Magnesia.The first famous mention of the city is in 190 BC, when Antiochus the Great was defeated in the battle of Magnesia by the Roman consul Lucius Cornelius Scipio Asiaticus.
