The book proposes that around the 15th century BCE, Venus was ejected from Jupiter as a comet or comet-like object and subsequently passed near Earth, though an actual collision with the Earth is not mentioned. In doing so it changed Earth's orbit and axial inclination, causing innumerable catastrophes which were identified in early mythologies and religious traditions from human civilizations around the world. Fifty-two years later, it again made a close approach, stopping the Earth's rotation for a while and causing more catastrophes. Then, in the 8th and 7th centuries BCE, Mars (itself displaced by Venus) made close approaches to the Earth; this incident caused a new round of disturbances and disasters. After that, the current "celestial order" was established. The courses of the planets stabilized over the centuries and Venus gradually became a "normal" planet.
