In Greco-Roman popular lore, a nonfatal lightning strike promised great distinction and fame. Similar beliefs held in the East too. According to the writings of the Magi (Persian Zoroastrian priest-astronomers), the savior-king was to be distinguished by a special mark on his body. The Magi in his father’s palace saw Mithradates’ lightning scar as a sign of divine approval; the diadem shape meant the gods had “crowned” him at birth.
