He was a contemporary of Diocletian . He at first persecuted Christians with great ferocity, but God"s punishment fell on him and he went mad and became like a beast, as happened aforetime to Nebuchadnezzar. St Gregory miraculously healed him of his madness (see Sept. 30th). From that time until his death, Tiridates spent his life in repentance and devotion. He died peacefully in the fourth century.
