PHILADELPHIA. - City of Lydia in Asia Minor, northwest of Mount Tmolus (today Bosdağ) in the Cogamia valley. Founded by Attalus II Philadelphus, king of Pergamum (159-138 B.C.), it came under Roman rule in 133 B.C. Restored through the generosity of Tiberius after the earthquake of 17 A.D., it received the title of "Neocaesarea" (on the coins of Tiberius, Caligula, and Claudius): under Vespasian, it was called "Flavia."
