The Cube
On my downloads page I placed a video that shows the dissection of the Cube in a Tetrahedron and four piramids. This dissection itself is known and described, for example, in Elisabeth Haich’s book “Initiation” (Einweihung, 1960). An introduction to the text I will place on this website on a modern version of Plato’s Elements.
