The fascinating thing is that this astronomical knowledge is spread all over the world through hundreds of cultures.

The basic premise of the book ("essay") _Hamlet's Mill_ is that the myth of Hamlet (and its variants) and in general all the ancient myths can be interpreted as a code language expressing the astronomical knowledge of precession of the equinoxes among ancient cultures.
