In the early period of Greek thought, light must be understood in most cases as a symbol for a reality that exceeds what can be grasped through the senses. It stands for luck, salvation, deliverance, victory and justice. Furthermore, the divine is elucidated through the image of light. In the epiphanies, something of the essence of the gods also becomes visible, as they appear incarnated in light. At Eleusis, initiation into the mysteries is experienced as illumination.
