Mount Sipylus
The name "Magnesia ad Sipylus" refers to Mount Sipylus (Mount Spil) that towers over the city and Magnesia became a city of importance starting with the Roman dominion, particularly after the 190 BC Battle of Magnesia. The names "Sipylus" or "Sipylum" in reference to a settlement here are also encountered in some sources, again in reference to the mountain and as abbreviated forms. Pliny the Elder, supported by other sources, mentions that formerly in the same place was a very celebrated city which was called "Tantalis" or "the city of Tantalus" whose ruins were still visible around his time.
