The center of gravity
“Every movement, he said, had a center of gravity; it would be sufficient to position this within the body of the figure; the limbs which were nothing but pendulums,
followed mechanically by their own accord, without the puppet-master having to do anything else.“
Heinrich von Kleist, About the Marionette Show
In many regards, a marionette is like a good violin. Its quality only reveals itself when it is played. Its construction calls for skill, care and knowledge.
