 Julian attempted to restore the Eleusinian Mysteries and was the last emperor to be initiated into them.The Roman emperor Theodosius I closed the sanctuaries by decree during the Persecution of pagans in the late Roman Empire about 30 years later, in 392 AD.The last remnants of the Mysteries were wiped out in 396 AD, when Arian Christians under Alaric, King of the Goths, destroyed and desecrated the old sacred sites.
