He crossed the level plains of the Nisasans, where the famous herds of horses, feeding in the wide pastures, tossed their heads at Vasda's approach, and galloped away with a thunder of many hoofs, and flocks of wild birds rose suddenly from the swampy meadows, wheeling in great circles with a shining flutter of innumerable wings and shrill cries of surprise. He traversed the fertile fields of Concabar, where the dust from the threshing-floors filled the air with a golden mist, half hiding the huge temple of Astarte with its four hundred pillars. At Baghistan, among the rich gardens watered by fountains from the rock, he looked up at the mountain thrusting its immense rugged brow out over the road, and saw the figure of King Darius trampling upon his fallen foes, and the proud list of his wars and conquests graven high upon the face of the eternal cliff. Over many a cold and desolate pass, crawling painfully across the wind-swept shoulders of the hills; down many a black mountain-gorge, where the river roared and raced before him like a savage guide; across many a smiling vale, with terraces of yellow limestone full of vines and fruit trees; through the oak groves of Carine and the dark Gates of Zagros, walled in by precipices; into the ancient city of Chala, where the people of Samaria had been kept in captivity long ago; and out again by the mighty portal, riven through the encircling hills, where he saw the image of the High Priest of the Magi sculptured on the wall of rock, with hand uplifted as if to bless the centuries of pilgrims; past the entrance of the narrow defile, filled from end to end with orchards of peaches and figs, through which the river Gyndes foamed down to meet him; over the broad rice-fields, where the autumnal vapors spread their deathly mists; following along the course of the river, under tremulous shadows of poplar and tamarind, among the lower hills; and out upon the flat plain, where the road ran straight as an arrow through the stubble-fields and parched meadows; past the city of Ctesiphon, where the Parthian emperors reigned, and the vast metropolis of Seleucia which Alexander built; across the swirling floods of Tigris and the many channels of Euphrates, flowing yellow through the corn-lands--Artaban pressed onward until he arrived, at nightfall of the tenth day, beneath the shattered walls of populous Babylon. Vasda was almost spent, and he would gladly have turned into the city to find rest and refreshment for himself and for her. But he knew that it was three hours' journey yet to the Temple of the Seven Spheres, and he must reach the place by midnight if he would find his comrades waiting. So he did not halt, but rode steadily across the stubble-fields. A grove of date-palms made an island of gloom in the pale yellow sea. As she passed into the shadow Vasda slackened her pace, and began to pick her way more carefully.
