Laodicea: Laodicea and Hierapolis were both cities of Phrygia in Asia Minor, between which, and equidistant from each, was situated Colosse. Laodicea was seated near the Lycus, about 63 miles east of Ephesus; and became one of the largest and richest towns in Phrygia, vying in power with the maritime cities. It is now called Eski-hissar, the old castle; and besides the whole surface within the city's wall being strewed with pedestals and fragments, the ruins of an amphitheatre, a magnificent odeum, and other public buildings, attest its former splendour and magnificence. But, when visited by Dr. Chandler, all was silence and solitude; and a fox, first discovered by his ears peeping over a brow, was the only inhabitant of Laodicea. Hierapolis, now Pambouk-Kaiesi, was situated, according to the Itinerary, six miles n of Laodicea; and its ruins are now about a mile and a half in circumference.
