Æ31 - Trajan ΙΕΡΑΠΟΛΕΙΤΩΝ

Hierapolis of Phrygia sat atop one of the ancient world's most striking geological formations — the calcium-rich thermal springs that built the travertine terraces now known as Pamukkale — and the city's prosperity under Trajan reflected its role as a commercial hub on the road network connecting the Maeander valley to the interior. Civic bronze coinage of this conventus was struck under the authority of the Roman proconsul of Asia, with individual cities bearing their own ethnic legends as a mark of retained civic identity within the provincial system.
