The Orphic school, a mystery cult that originated in Thrace and spread to Greece in the 5th century BCE, held similar beliefs about the early days of man, likewise denominating the ages with metals. In common with the many other mystery cults prevalent in the Graeco-Roman world (and their Indo-European religious antecedents), the world view of Orphism was cyclical. Initiation into its secret rites, together with ascetic practices, was supposed to guarantee the individual's soul eventual release from the grievous circle of mortality and also communion with god(s). Orphics sometimes identified the Golden Age with the era of the god Phanes, who was regent over the Olympus before Cronus. In classical mythology however, the Golden Age was associated with the reign of Saturn. In the 5th century BCE, the philosopher Empedocles, like Hesiod before him, emphasized the idea of primordial innocence and harmony in all of nature, including human society, from which he maintained there had been a steady deterioration until the present.
