Many great paintings and poems are records of things discovered in this quietness of light.
It is indeed ironical in our Ali Baba's cave to see sheer everydayness and hardness upon the screen, the audience dragged back to the street they have escaped.

One of the inventions to bring the twilight of the gathering into brotherhood with the shadows on the screen is a simple thing known to the trade as the fadeaway, that had its rise in a commonplace fashion as a method of keeping the story from ending with the white glare of the empty screen.

As a result of the device the figures in the first episode emerge from the dimness and in the last one go back into the shadow whence they came, as foam returns to the darkness of an evening sea.

In the imaginative pictures the principle begins to be applied more largely, till throughout the fairy story the figures float in and out from the unknown, as fancies should.

This method in its simplicity counts more to keep the place an Ali Baba's cave than many a more complicated procedure.
