This is Andre VandenBroeck's title for a book he wrote about the 18 months he spent with Schwaller de Lubicz in 1959-1960. As he says "Al-Kemi means Pharaonic Egypt," expressed by the hieroglyph indicating black land. VandenBroeck had experienced a "breakthrough" before meeting de Lubicz and one of the questions he had when he was growing up was why the musical measure starts with one and not zero, as other measurements are made. He also discusses the tritone, the musical interval dividing the octave in half under equal temperament tuning. As he explains, Schwaller de Lubicz's perspective on Egypt was not one of an Egyptoligist; he saw Egypt through number, de Lubicz said it was saying the same thing that medieval texts he had already studied said. The "moment" for de Lubicz was the point of imbalance. Many of de Lubicz's ideas correspond to ideas of the Fourth Way, i.e. "third-term," "salt." For a further elaboration of de Lubicz's work see John Anthony West's book Serpent in the Sky.
