who tried to revive the traditional roman state religion
Decline of Greco-Roman polytheism As Emperor, Julian sought to turn the tide in the attempted suppression of non-Christian religions. As his first task he sought to reestablish the old Roman Pagan practice of incorporation of other religions. But now instead of allowing different cults using different names for the same or similar deities, Julian's training in Christianity and Imperial government influenced him to develop a single pagan religion. Thus, his ideas concerning the revival and organization of the old religion, shaping it into a coherent body of doctrine, ritual and liturgy[2] with a hierarchy under the supervision of the emperor was the hallmark of his reign.[36] Julian organized elaborate rituals and attempted to set forth a clarified philosophy of Neo-Platonism that might unite all Pagans.[37]
