The city walls were built of huge square stones, and among the groves towered pyramids, on which the people did service to their gods. From every temple top came the roar of beaten drums, great drums of serpentskin. But, in the centre of the chief square of the town, was gathered a wild crowd of men in shining copper armour and helmets of gold and glittering dresses of feathers. Among them ran about priests with hideous masks, crying them on to besiege and break down the royal palace. From the battlements of the palace the king's guardsmen were firing arrows and throwing spears. The mob shot arrows back, some of them tipped with lighted straw, to burn the palace down. But, in the very centre of the square, was a clear space of ground, on which fell the shadow of a tall column of red stone, all carved with serpents and faces of gods. Beside it stood a figure horrible to see: a man clothed in serpent skins, whose face was the grinning face of a skull; but the skull was shining black and red in patches, and a long white beard flowed from beneath it. This man, mounted on a kind of altar of red stone, waved his hand and yelled, and seemed to point to the shadow of the column which fell across the square. The people were so furious and so eager that they did not, at first, notice King Prigio as he slowly descended. But at last the eyes within the skull looked up and saw him, and then the man gave a great cry, rent his glittering dress of serpentskin, and held up his hands. Then all the multitude looked up, and seeing the Flying Horse, let their weapons fall; and the man of the skull tore it from his face, and knelt before King Prigio, with his head in the dust. "Thou hast come, oh, Pachacamac, as is foretold in the prophecy of the Cord of the Venerable Knots! Thou hast come, but behold the shadow of the stone! Thou art too late, oh Lord of the Earth and the Sea!" Then he pointed to the shadow, which, naturally, was growing shorter, as the sun drew near mid-day. He spoke in the language of the ancient Incas of Peru, which of course Prigio knew very well; and he also knew that Pachacamac was the god of that people. "I have come," Prigio said, with presence of mind, "as it has been prophesied of old." "Riding on a beast that flies," said the old priest, "even as the oracle declared. Glory to Pachacamac, even though we die to-day!" "In what can I help my people?" said Prigio.
