Precessie-beweging van de Aarde. De Aarde roteert (witte pijlen) eenmaal daags rond haar rotatie-as (rood); deze as roteert zelf langzaam (witte cirkel), en maakt de volledige rotatie compleet in ongeveer 26.000 jaar
Het gaat met name over de bewering van de ontdekking van de axiale precessie in de megalithische tijd en het coderen van deze kennis in mythologie.
Het boek werd na publicatie zwaar door academici bekritiseerd.
Barber & Barbers When They Severed Earth from Sky: How the Human Mind Shapes Myth (2024) waardeerde het boek voor het pionierswerk in mythografie.
↑Puhvel 1970, p.2009: "The cowed reviewer is soon reduced to wondering whether mere critical prose should even be expended on something that obviously solicits the suspension of disbelief." Leach 1970: "As will presently be apparent, my reaction to this book is hostile – so before my prejudices get out of hand, let me try to explain what it is all about." White, Jr. 1970, p.541: "De Santillana has served us well once more by underscoring a pioneering idea, but von Dechend's implementation of that idea will prevent many scholars from recognizing its validity."

↑Payne-Gaposchkin 1972, p.206: "Hamlet's Mill is hard to classify. It recalls Charles Venables's assessment of Maggie Shand: "You ... are such a mixture of the practical and the emotional that you escape out of [the] hand like a trout." In what follows I shall try to explain why, after several readings, I place it in Category (2); the authors have not proved their point."
