Immanuel Velikovsky called this book the "fulfillment of his oath of Hippocrates - to serve humanity." In this book, he returns to his roots as a psychologist and psychoanalytical therapist, yet not with a single person as his patient but with humanity as a whole.

In his main work, the best-selling Worlds in Collision, Immanuel Velikovsky gave a detailed reconstruction of two global natural catastrophes based on information handed down by our ancestors. He mentions there that, as part of his intensive research, he found numerous indications of even more catastrophes that took place earlier in the history of mankind.

Worlds in Collision - written in a brilliant, easily understandable, and entertaining style and full to the brim with precise information-can be considered one of the most important and most challenging books in the history of science. Not without reason was this book found open on Einstein's desk after his death. For all those who have ever wondered about the evolution of the earth, the history of mankind, traditions, religions, mythology or just the world as it is today, Worlds in Collision is an absolute must-listen!

No other monument in the world evokes mystery like the Great Sphinx of Giza. It has survived the harsh climate of Egypt for thousands of years and will remain long after our own civilization is gone. According to orthodox Egyptology, the Sphinx was built around 2500 BCE as a memorial to the pharaoh Khafre. Yet this “fact” has scant to no supportive evidence. When was the Sphinx really built and, most importantly, why?

Less than 50,000 years ago mankind had no art, no religion, no sophisticated symbolism, no innovative thinking. Then, in a dramatic and electrifying change, described by scientists as "the greatest riddle in human history," all the skills and qualities that we value most highly in ourselves appeared already fully formed, as though bestowed on us by hidden powers. In Visionary, Graham Hancock sets out to investigate this mysterious "before-and-after moment" and to discover the truth about the influences that gave birth to modern human mind.
