“invented” it. Any creature in motion is a wheel in that 
repetition of movement has a cyclic and circular principle in it. 
Thus the melodies of literate societies are repeatable cycles. 
But the music of nonliterate people has no such repetitive cyclic 
and abstract form as melody. Invention, in a word, is 
translation of one kind of space into another.

     Giedion devotes some time to the work of the French 
physiologist, Etienne Jules Morey (1830­1904), who devised 
the myograph for recording the movements of muscles: “Morey 
quite consciously looks back to Descartes, but instead of 
graphically representing sections he translates organic 
movement into graphic form.” (p. 19)
