Zarathustra descending from his cave in the mountains after ten years of solitude. He is brimming with wisdom and love, and wants to teach humanity about the overman. He arrives in the town of the Motley Cow, and announces that the overman must be the meaning of the earth. Mankind is just a bridge between animal and overman, and as such, must be overcome. The overman is someone who is free from all the prejudices and moralities of human society, and who creates his own values and purpose.
The people on the whole seem not to understand Zarathustra, and not to be interested in the overman. The only exception is a tightrope walker who has fallen and who dies shortly thereafter.
