In England the movie theatre was originally called “The Bioscope,” because of its visual presentation of the actual movements of the forms of life (from Greek bios , way of life). The movie, by which we roll up the real world on a spool in order to unroll it as a magic carpet of fantasy, is a spectacular wedding of the old mechanical technology and the new electric world. In the chapter on The Wheel, the story was told of how the movie had a kind of symbolic origin in an attempt to photograph the flying hooves of galloping horses, for to set a series of cameras to study animal movement is to merge the mechanical and the organic in a special way. In the medieval world, curiously, the idea of change in organic beings was that of the substitution of one static form for another, in sequence. They imagined the life of a flower as a kind of cinematic strip of phases or essences. The movie is the total realization of the medieval idea of change, in the form of an entertaining illusion.
