It was high, wide, and deep, the latter dimension giving the actual width of the wall itself. Croft judged it to be nearly as wide as tall. Then it was passed, and he found himself gazing upon such a scene as had never met mortal eyes perhaps since the days of Babylon. The great river flowed straight before him for a distance so great that the farther wall was lost in a shimmering haze of heat. It flowed between solid walls of stone, cut and fitted to perfect jointure. From the lowest quay the banks sloped back in gentle terraces, green with grass and studded with trees and blooming masses of flowers and shrubs. Huge stairways and gradually sloping roadways ran from terrace to terrace, down the river's course. And back of the terraced banks there stretched off and away the splendid piles of house after house, huge, massive, each a palace in itself, until beyond them, seemingly halfway down the wonderful river gardens, there loomed a structure greater, vaster, more wide flung than any of the rest. In the light of the risen sun it shone an almost blinding white. To Croft at that distance it appeared built of an absolutely spotless stone. * * * * * As for the other houses, surely as he felt the abodes of the nobles and the rich, they were constructed mainly of red sandstone, red granites and marbles, although here and there was one which glowed white through the surrounding trees, or perhaps a combination of red and white both. Yet, aside from the monster structure in the distance, the majority were red. Indeed, he was to come to know later that the word Himyra meant red in the literal sense; that in the Palosian tongue this was the "red city," just as he was to learn also that the name of the mighty river was Na, because of its yellow colored flood. But this morning he knew none of that as he gazed down the terraced vista, bathed in the rays of Sirius, now rapidly mounting the sky. And there was much to see. Across from the vast white building, on the other side of the river Na, he beheld a pyramid. He could call it nothing else in his earthly mind. It, too, was huge, vast--a monster red pile, rising high above all other buildings in the city, until near the top was a final terrace or story of blinding white, capped with a finishing band of red; the whole thing supporting a pure white structure, pillared and porticoed like a temple on its truncated top. Even in the distance it was a monster thing. How large he could not tell. Later he was to know it was two thousand feet square at the base, and three hundred feet in its rise above its foundation, ere the temple of Zitu was reached.
