In it, Leabhart explains that modern mime, a major creative art form in recent years, has its roots in the work Jacques Copeau did at the Ecole de Vieux-Colombier in Paris in the 1920s.
In his classes (one of which, called 'corporeal mime,' inspired Etienne Decroux to develop the mime technique of the same name), Copeau emphasized the expressive potential of the actor's whole body, rather than the voice, hands and face (though his actors trained to use those, as well).
Leabhart examines the contributions of Decroux, Jean-Louis Barrault, Marcel Marceau, and Jacques Lecoq to the development of this new form.
