The mask is not to be carelessly assumed or lightly put off. Primitive man knows that there must be initiation and a certain ceremony. If he puts on a false face without the proper incantation, there will be no power in it. It is the purpose of the following pages to try to bridge by just a little the gap that lies between the primitive man who puts a sort of idol on his face, and the Greek tragedian; between the Duk-Duk dancer who regulates morals and acquires riches in New Guinea, and some artist of the theater who wishes to bring the mask back to the stage. Illustrated throughout.
