Thoughts on the Maritime Bell-Beakers, Iberian Graves & Egypt by Stone Age Herbalist. I recently read 'The Horse, the Wheel and Language' by David W Anthony and am almost finished 'Indo-European Poetry and Myth' by ML West but it was really Ludwig Klages mentions of the 'Pelasgians' - a pre-Indo-European people living in Greece that made this essay stand out to me. As a pure hobbyist my intuition is that the 'categories' of archaeological investigations are less stable than a theorist might hope, and the idea of a humming, trading, mutating world in this time is compelling to the imagination especially in light of Uzdavinys' arguments regarding the Egyptian influence on Greece.
