Book excerpt: Most of the "wonders" of our ancient past have come down to us unencumbered by written information. In particular, this is the case of the Great Pyramid of Giza and of many other ancient Egyptian monuments. However, there is no doubt as to the interest of their builders in the celestial cycles: the "cosmic order" was indeed the true basis of the pharaoh's power. This book takes the reader on a chronological journey through ancient Egypt to explore the relationship between astronomy, landscape, and power during the most flourishing periods of ancient Egyptian civilization. Using the lens of archaeoastronomy, Giulio Magli reexamines the key monuments and turning points of Egyptian architecture and history, such as the solar deification of King Khufu, builder of the Great Pyramid, the Hatshepsut reign, and the Amarna revolution.
