Night and day, month after month, year after year, our ancestors dutifully recorded the passage of time on clay tablets, watching the heavens from stage towers and pyramids and from megalithic monuments whose incredible size and precise architecture boggle the mind… . Who were the builders of these mysterious structures? What was their purpose? Whose signature is indelibly written on these timeless stones, and who was the Divine Architect? Why was Stonehenge and its likes built by ancient civilizations at the very same time–4,100 years ago? What is their message for our time? With these questions in mind, Zecharia Sitchin, renowned researcher of past ages, takes us on a journey through the records of time in this, the fifth book of his Earth Chronicles series. Drawing deeply on Sumerian and Egyptian writings, millenia-old artifacts, and sacred architecture ranging from ancient Mesopotamia to pre-Columbian civilizations in the Americas, this bestselling scholar provides astounding insights into the origins of the calendar, astronomy, and astrology. He takes readers to the climax circa 2100 b.c. when Marduk, the Babylonian national god, attained supremacy on Earth and proclaimed the New Age of Aries–after which society, religion, science, and the status of women were never the same.
