Hamlet's Mill: An Essay Investigating the Origins of Human Knowledge and Its Transmission Through Myth (first published by Gambit, Boston, 1969) by Giorgio de Santillana (a professor of the history of science at MIT) and (a scientist at Johann Wolfgang Goethe-Universität) is a nonfiction work of history and comparative mythology, particularly the subfield of archaeoastronomy. It is mostly about the claim of a Megalithic era discovery of axial precession and the encoding of this knowledge in mythology. The book was severely criticized by academics upon its publication.
