In the distance they perceived a troop of horse-men galloping on horses without bridles. Their golden bracelets leaped in the vague drapings of their cloaks. A man could be seen in front crowned with ostrich feathers, and galloping with a lance in each hand.
“Narr’ Havas!” exclaimed Matho.
“What matter?” returned Spendius, and he leaped into the hole which they had just made by removing the flagstone.
Matho at his command tried to thrust out one of the blocks. But he could not move his elbows for want of room.
“We shall return,” said Spendius; “go in front.” Then they ventured into the channel of water.
It reached to their waists. Soon they staggered, and were obliged to swim. Their limbs knocked against the walls of the narrow duct. The water flowed almost immediately beneath the stones above, and their faces were torn by them. Then the current carried them away. Their breasts were crushed with air heavier than that of a sepulchre, and stretching themselves out as much as possible with their heads between their arms and their legs close together, they passed like arrows into the darkness, choking, gurgling, and almost dead. Suddenly all became black before them, and the speed of the waters redoubled. They fell.
When they came to the surface again, they remained for a few minutes extended on their backs, inhaling the air delightfully. Arcades, one behind another, opened up amid large walls separating the various basins. All were filled, and the water stretched in a single sheet throughout the length of the cisterns. Through the air-holes in the cupolas on the ceiling there fell a pale brightness which spread upon the waves discs, as it were, of light, while the darkness round about thickened towards the walls and threw them back to an indefinite distance. The slightest sound made a great echo.
Spendius and Matho commenced to swim again, and passing through the opening of the arches, traversed several chambers in succession. Two other rows of smaller basins extended in a parallel direction on each side. They lost themselves; they turned, and came back again. At last something offered a resistance to their heels. It was the pavement of the gallery that ran along the cisterns.
Then, advancing with great precautions, they felt along the wall to find an outlet. But their feet slipped, and they fell into the great centre-basins. They had to climb up again, and there they fell again. They experienced terrible fatigue, which made them feel as if all their limbs had been dissolved in the water while swimming. Their eyes closed; they were in the agonies of death.
Spendius struck his hand against the bars of a grating. They shook it, it gave way, and they found themselves on the steps of a staircase. A door of bronze closed it above. With the point of a dagger they moved the bar, which was opened from without, and suddenly the pure open air surrounded them.
