In this landmark series of lectures, Rudolf Steiner challenges the notion that human consciousness has in essence remained the same throughout history. On the contrary, we can only see the past in its true light when we study the differences in human souls during the various historical eras. Consciousness, he says, evolves constantly and we can only comprehend the present by understanding its origin in the past.Delivered in the evenings during the course of the 'mystery act' of the Christmas Foundation Meeting - when Rudolf Steiner not only re-founded the Anthroposophical Society but for the first time took a formal role within it - these lectures study world history in parallel with the ancient mysteries of initiation, showing how they are intimately linked. Steiner describes consciousness in the ancient East and follows the initiation principle from Babylonia to Greece, up to its influences in present-day spiritual life. He also discusses Gilgamesh and Eabani, the mysteries of Ephesus and Hibernia, and the occult relationship between the destruction by fire of the Temple of Artemis and the burning of the first Goetheanum in Dornach, Switzerland.Published for the first time with colour plates of Steiner's blackboard drawings, the freshly-revised text is complemented with an introduction, notes and appendices by Professor Frederick Amrine and an index.
