Hermus (now Gediz Çayı), the largest river on the west coast of Asia Minor after the *Maeander, is mentioned by Homer (Il. 20. 392). Herodotus (1. 80, cf. Strabo 626, Plin. HN 5. 119) says it rises on the holy mountain of the Dindymene Mother in *Phrygia (now Murat Dağı) and enters the sea by *Phocaea. This is also its present course; but at some unknown time it left its bed and turned to the south after passing the gorge west of *Magnesia (2) ad Sipylum and ran into the gulf of *Smyrna. In 1886, to save the gulf from becoming silted up, the river was diverted back into its ancient bed. Among its tributaries are the Hyllus and the gold-bearing Pactolus. The many personal names in Herm- may be from the river, or from the god *Hermes.
