Malkowski, Edward F. *
Edward F. Malkowski is an American writer who coined the phrase ‘Civilisation X’ to describe a prehistoric ‘Greater Mediterranean civilisation’. exemplified by pre-dynastic Egypt. His earlier Before the Pharaohs  was soon followed by Ancient Egypt 39,000 BCE . Although he refers to Atlantis(a), he is somewhat ambivalent regarding its existence [657.284].
However, Malkowski is thoroughly fascinated by the Giza monuments, particularly the Great Pyramid(c), regarding which, he follows the ideas of Edward Kunkel(d) and John Cadman(e), who proposed that the Great Pyramid functioned as a water pump. However, Malkowski believes that such a pump had an additional function, namely, to generate compression waves that in turn would cause the pyramid’s granite beams to vibrate. Then, “with shafts leading to the Great Pyramid’s exterior, the ‘singing’ granite would project its sound into the atmosphere. This, in turn, would create an electrical field in the atmosphere according to physics research.” (f) This gentle electrical field would have been used to generate plant growth in the surrounding land. Why it would be necessary to build such a huge ‘machine’ to promote growth on land that is renowned for its annually renewed fertility with the flooding of the Nile, completely eludes me.
He has also written an interesting paper on Ice Age theories, which ends on a note of personal scepticism regarding currently accepted ideas(b).
