magnesia
(now Manissa). A town of Lydia, usually mentioned with the addition of ad Sypilum (“at or near Sypilus”) to distinguish it from Magnesia on the Mæander, in Ionia, situated on the northwestern slope of Mount Sypilus. It is chiefly celebrated in history for the victory gained under its walls in 190 B.C. by the two Scipios over Antiochus the Great, whereby that monarch was forever driven from Western Asia. The town after the victory of the Scipios surrendered to the Romans.
