 The closing of the Eleusinian Mysteries in the 4th century is reported by Eunapius, a historian and biographer of the Greek philosophers.Eunapius had been initiated by the last legitimate Hierophant, who had been commissioned by the emperor Julian to restore the Mysteries, which had by then fallen into decay.According to Eunapius, the very last Hierophant was a usurper, "the man from Thespiae who held the rank of Father in the mysteries of Mithras".
