was no doubt about the masculinity of any male in Diaspar. It was merely that his equipment was now more neatly packaged when not required; internal stowage had vastly improved upon Nature’s original inelegant and indeed downright hazardous arrangements.
It was true that reproduction was no longer the concern of the body, being far too important a matter to be left to games of chance played with chromosomes as dice. Yet, though conception and birth were not even memories, sex remained. Even in ancient times, not one-hundredth part of sexual activity had been concerned with reproduction. The disappearance of that mere one per cent had changed the pattern of human society and the meaning of such words as “father” and “mother”— but desire remained, though now its satisfaction had no profounder aim than that of any of the other pleasures of the senses.
Alvin left his playful contemporaries and continued on toward the center of the park. There were faintly marked paths here, crossing and crisscrossing through low shrubbery and occasionally diving into narrow ravines between great lichen-covered boulders. Once he came across a small polyhedral machine, no larger than a man’s head, floating among the branches of a tree. No one knew how many varieties of robot there were in Diaspar; they kept out of the way and minded their business so effectively that it was quite unusual to see one.
Presently the ground began to rise again; Alvin was approaching the little hill that was at the exact center of the park, and therefore of the city itself. There were fewer obstacles and detours, and he had a clear view to the summit of the hill and the simple building that surmounted it. He was a little out of breath by the time he had reached his goal, and was glad to rest against one of the rose-pink columns and to look back over the way he had come.
There are some forms of architecture that can never change because they have reached perfection. The Tomb of Yarlan Zey might have been designed by the temple builders of the first civilizations man had ever known, though they would have found it impossible to imagine of what material it was made. The roof was open to the sky, and the single chamber was paved with great slabs which only at first sight resembled natural stone. For geological ages human feet had crossed and recrossed that floor and left no trace upon its inconceivably stubborn material.
The creator of the great park— the builder, some said, of Diaspar itself— sat with slightly downcast eyes, as if examining the plans spread across his knees. His face wore that curiously elusive expression that had baffled the world for so many generations. Some had dismissed it as no more than an idle whim of the artist’s, but to others it seemed that Yarlan Zey was smiling at some secret jest.
The whole building was an enigma, for nothing concerning it could be traced in the historical records of the city. Alvin was not even sure what the word “Tomb” meant; Jeserac could probably tell him, because he was fond of collecting obsolete words and sprinkling his conversation with them, to the confusion of his listeners.
From this central vantage point, Alvin could look clear across the park, above the screening trees, and out to the city itself. The nearest buildings were almost two miles away, and formed a low belt completely surrounding the park. Beyond them, rank after rank in ascending height, were the towers and terraces that made up the main bulk of the city. They stretched for mile upon mile, slowly climbing up the sky, becoming ever more complex and monumentally impressive. Diaspar had been planned as an entity; it was a single mighty machine. Yet though its outward appearance was almost overwhelming in its complexity, it merely hinted at the hidden marvels of technology without which all these great buildings would be lifeless sepulchers.
Alvin stared out toward the limits of his world. Ten— twenty miles away, their
