A few miles north of Laodicea in the Lycus Valley, the ruins of Hierapolis stand along the ancient roadway connecting Laodicea to Philadelphia and Sardis to the northwest. The ruins demonstrate it was a prosperous trade center built around hot springs that were considered a source of healing power in the Roman period. In the southwestern edge of the Phrygian territory, the city is perched 250 feet above on a natural terrace overlooking the surrounding valley. The ancient city had all the drawing points of a resort, with all the regional goods of the other regional cities: wools, dying trades and textiles.
The city of Hierapolis, which was founded on this site in the 2nd century B.C., differs from all other ancient cities in being located, not on earth or rock, but on solid limestone layers formed by limestone water that flowed for centuries over this raised level plateau.
"Hierapolis" can mean "sacred city", and according to Stephanus of Byzantium the city was given this name because of the large number of temples it contained.
Up to the reign of Augustus the city was officially described on coins as Hierapolis, the city of temples, but it seems reasonable to assume that this was not the original meaning of the name.
The founder of the city was Eumenes II, King of Pergamon, and it was the custom for Hellenistic kings to name the cities they founded after members of their own families. It thus seems much more likely that the city was named after Hiera or Hiero, the wife of Telesphorus, the legendary founder of the Pergamene dynasty.We have no definite records concerning the foundation of Hierapolis, but the tradition that it was founded by the Pergamenes would appear to be reliable.
There are many coins of Augustus issued from here with many different magistrates. Dating is roughly possible as the magistrates issued coins for proconsul Fabius Maximus (Group 1) and Gaius Caesar (Group 2)also. There is another group also which appears to be slightly later in the Augustan reign (Group 3).
