Гедиз
There are different accounts related to the historical origin of the Greek-derived name of "Menemen" (Μενεμένη or Μαινεμένη in Greek language). The most commonly encountered explanation based on the ancient Greek word "mainómenos" (μαινόμενος "furious, raving, out of one's mind"), which refers to a Greek Mythology story when Herakles went out of his mind for which Euripides wrote the play "Herakles Mainomenos" (). In addition, "meneménos" (μενεμένος) meant "flood" or "overflow". In the absence of modern dams and other means of waterflow control in antiquity, the Hermos River (now Gediz River) used to cause serious and frequent damages in the valley until recent times. The river was nicknamed in Turkish "Gediz the Sorceress" ("Cadı Gediz").
