Science Catches Up With Laban

The ancient Greeks knew that there were only five three dimensional symmetrical shapes – the tetrahedron, cube, octahedron, dodecahedron, and icosahedron. The first four shapes occur in nature, in various inorganic crystals. But the icosahedron appeared to exist only in mathematicians’ imaginations.




However, as Dr. Eugenia Cheng noted in a recent Wall Street Journal article, once electron microscopes were invented [circa 1930], “we discovered that many viruses, in fact, have icosahedron structures.” Since the latter discovery around 1950, Cheng adds, modern uses for the icosahedral shape have been found, such as geodesic domes and soccer balls.


Laban began using the icosahedron as a 3-D longitude and latitude for the human kinesphere in the 1920s. This crystalline shape seems to belong uniquely to the morphology of living organisms. Was Laban prescient?  Why did the icosahedron become his favorite shape for mapping human movement? Find out more in the upcoming correspondence course, “Decoding Choreutics.”
