IT was a beautiful cloudless day in July. The atmosphere quivered like the breath of a fire over the wide Pontine Marshes. The intense, stifling heat of midday seemed to come from the infernal regions. In invisible clouds pestilential vapors, breathing death, floated in the air. Luxuriant vegetation that had fed on decayed plants for centuries gave forth a putrefying and sickening odor. Dragon-flies sported about in the fever-breeding effluvium. For weeks there had been no rain, and the stream that glides through the marsh, like a river of death, was low and nearly stagnant. By the drying up of the stream and the mire the dust had encroached upon the marsh. Here and there small whirlwinds of dust were twisting, like venomous spirits of the air. Through this death-breeding district, which appeared like a huge sore on the fair plains of Campania, led the Via Appia, connecting Terracina with Forum Appii. Over the road the dust had drifted like snow, but unlike snow it did not melt under the burning sun.

At midday the road was always deserted. The beasts of burden and their drivers would rest in the inns and taverns until the sun slanted its rays. But on this day a cloud of dust moved slowly along the road. From time to time there appeared in the cloud the glitter of a helmet, the flash of a spear. A company of equestrian soldiers were escorting a carriage drawn by two horses. Evidently something urgent kept these soldiers on the road this sultry, stifling day.

There being but a slight breeze, the dust fell where it rose, covering the party with a thin yellow layer. The horses breathed hard and sneezed and snorted as the irritating dust penetrated their nostrils. The sun at its zenith beat unmercifully upon the cavalcade. With eyes half closed and cast down, the men moved on, suffering under the intense heat. No one spoke. The clanking of the iron shoes of the horses and the rattling of the swords of the soldiers were the only sounds that broke the silence.

On, on, they marched, the perspiration rolling like little rivulets down the soldiers’ cheeks, through the coating of dust. The beasts’ flanks were also wet with a mixture of dust and sweat. Occasionally the officer in charge would give an order so as to encourage the men. Some of the horses began to stumble as they dragged one foot after another. One of them with its sides bloody from the constant spurring of its rider, was gradually left behind the others. The rider dismounted, and with the flat of his sword began to beat the beast. After vain efforts to keep up, the poor horse finally stumbled and dropped upon the burning road to die. The rider proceeded on foot. The sun still relentlessly blazed, and scorched the party. There was no tree along the road, no place where shelter could be found, and there was nothing to do but to travel on.

On, on, on, they went, becoming more and more fatigued as each mile-post was passed. The carriage rolled along the road like a funeral car. From time to time there came from within the drawn curtains the noise of clanking chains. Coughs and gasps, produced by the stifling dust and heat, were mingled with deep and prolonged sighs. When the party arrived at the almost stagnant stream, a boat conveyed the carriage from one side to the other. While the carriage was in the stream, the curtains were drawn aside and one of the occupants looked out, but immediately drew back. The sun burnt too fiercely. The horses walked through the poisonous waters and became slightly refreshed by the passage, but the respite endured only a short time. Again they were on the hot road, proceeding towards Terracina.

The occupants of the carriage were Agrippina and Psyche. Agrippina’s wrists were bound together by chains. She rested her head on Psyche’s shoulder. All night long they had been on the move and she had had no rest.

“Is it not possible to obtain more air?” asked Agrippina.

“I fear not, my lady,” said Psyche, in a tone of forced cheerfulness. “Would that I could bathe thy head with water, but even water is denied us.”

“Ah! these chains are too heavy. Look how they have cut my wrists.”

“Place the weight on the seat, my lady. There—does not that ease thee a little?”
