The servo-robot explained, after much searching among its tapes for words:

"This is the spirit of the famous Mona Lisa smile. The Happy Time artist has cleverly removed all non-essential detail so that you can get the meaning of the picture in the minimum amount of time."

Walther studied the thin, wavering line. This, then, was Da Vinci's eternal enigma of womanhood. Perhaps it explained why he felt there were two Marias. Could there be one whole woman in a culture of fragmented lives?

The portraits of Holbein were reduced to a few sprinkles of geometric designs shot through with a single brilliant color. The nudes of Watteau, Rubens and Velazquez were little more than shadow curves.

In the east wing of the Louvre, the servo-robot pointed to a series of larger paintings. Each of these, Walther learned, summarized the entire life work of a single artist. Here it was possible to see all of Titian or Michaelangelo or Van Gogh on one simplified canvas.

Where were the originals of these classics? In the cultural vaults at Uniport, the servo-robot explained. Only authorized Happy Time artists could work with them.

Afterwards, Walther was never quite certain what happened to the rest of his day. Distraught, he wandered around the Earth, changing from stratoway to stratoway, scarcely paying any heed to his next destination. Rome, Athens, Moscow, Jerusalem. Everywhere the pace of leisure was the same. Capetown, New Delhi, Tibet, Tokyo, San Francisco. Everywhere he saw something that crumbled his dream a little more: The Buddhist monk pausing for ten seconds of meditation while he counted his beads, not one by one but in groups of twenty; the World Government Chamber where the Senator from the United States filibustered a proposal to death by speaking for the unprecedented period of four minutes; the cafe near the school where teenage boys and girls, immense numbers of them, danced, snapped their fingers and shrieked ecstatically as the latest popular record exploded in a wild three-note burst of sound.

It was seven o'clock in the evening before Walther became aware of the time. He was half the Earth and just one hour away from his meeting with Willy Fritsh.
