Once upon a time the Prince of Felicitas had occasion to set forth on a journey. It was a late autumn evening with few pale stars and a moon no larger than the paring of a finger-nail. And as he rode through the purlieus of his city, the white mane of his amber-coloured steed was all that he could clearly see in the dusk of the high streets. His way led through a quarter but little known to him, and he was surprised to find that his horse, instead of ambling forward with his customary gentle vigour, stepped carefully from side to side, stopping now and then to curve his neck and prick his ears-as though at some thing of fear unseen in the darkness; while on either hand creatures could be heard rustling and scuttling, and little cold draughts as of wings fanned the rider's cheeks.
The Prince at last turned in his saddle, but so great was the darkness that he could not even see his escort.
"What is the name of this street?" he said.
"Sire, it is called the Vita Publica."
"It is very dark." Even as he spoke his horse staggered, but, recovering its foothold with an effort, stood trembling violently.
Nor could all the incitements of its master induce the beast again to move forward.
"Is there no one with a lanthorn in this street?" asked the Prince.
His attendants began forthwith to call out loudly for any one who had a lanthorn. Now, it chanced that an old man sleeping in a hovel on a pallet of straw was, awakened by these cries. When he heard that it was the Prince of Felicitas himself, he came hastily, carrying his lanthorn, and stood trembling beside the Prince's horse. It was so dark that the Prince could not see him.
"Light your lanthorn, old man," he said.
The old man laboriously lit his lanthorn. Its pale rays fled out on either hand; beautiful but grim was the vision they disclosed. Tall houses, fair court-yards, and a palm grown garden; in front of the Prince's horse a deep cesspool, on whose jagged edges the good beast's hoofs were planted; and, as far as the glimmer of the lanthorn stretched, both ways down the rutted street, paving stones displaced, and smooth tesselated marble; pools of mud, the hanging fruit of an orange tree, and dark, scurrying shapes of monstrous rats bolting across from house to house. The old man held the lanthorn higher; and instantly bats flying against it would have beaten out the light but for the thin protection of its horn sides.
The Prince sat still upon his horse, looking first at the rutted space that he had traversed and then at the rutted space before him.
"Without a light," he said, "this thoroughfare is dangerous. What is your name, old man?"
"My name is Cethru," replied the aged churl.
"Cethru!" said the Prince. "Let it be your duty henceforth to walk with your lanthorn up and down this street all night and every night,"--and he looked at Cethru: "Do you understand, old man, what it is you have to do?"
The old man answered in a voice that trembled like a rusty flute:
"Aye, aye!--to walk up and down and hold my lanthorn so that folk can see where they be going."
The Prince gathered up his reins; but the old man, lurching forward, touched his stirrup.
"How long be I to go on wi' thiccy job?"
"Until you die!"
Cethru held up his lanthorn, and they could see his long, thin face, like a sandwich of dried leather, jerk and quiver, and his thin grey hairs flutter in the draught of the bats' wings circling round the light.
"'Twill be main hard!" he groaned; "an' my lanthorn's nowt but a poor thing."
With a high look, the Prince of Felicitas bent and touched the old man's forehead.
"Until you die, old man," he repeated; and bidding his followers to light torches from Cethru's lanthorn, he rode on down the twisting street. The clatter of the horses' hoofs died out in the night, and the scuttling and the rustling of the rats and the whispers of the bats' wings were heard again.
Cethru, left alone in the dark thoroughfare, sighed heavily; then, spitting on his hands, he tightened the old girdle round his loins, and slinging the lanthorn on his staff, held it up to the level of his waist, and began to make his way along the street. His progress was but slow, for he had many times to stop and rekindle the flame within his lanthorn, which the bats' wings, his own stumbles, and the jostlings of footpads or of revellers returning home, were for ever extinguishing. In traversing that long street he spent half the night, and half the night in traversing it back again. The saffron swan of dawn, slow swimming up the sky-river between the high roof-banks, bent her neck down through the dark air-water to look at him staggering below her, with his still smoking wick. No sooner did Cethru see that sunlit bird, than with a great sigh of joy he sat him down, and at once fell asleep.
Now when the dwellers in the houses of the Vita Publica first gained knowledge that this old man passed every night with his lanthorn up and down their street, and when they marked those pallid gleams gliding over the motley prospect of cesspools and garden gates, over the sightless hovels and the rich-carved frontages of their palaces; or saw them stay their journey and remain suspended like a handful of daffodils held up against the black stuffs of secrecy--they said:
"It is good that the old man should pass like this--we shall see better where we're going; and if the Watch have any job on hand, or want to put the pavements in order, his lanthorn will serve their purpose well enough." And they would call out of their doors and windows to him passing:
"Hola! old man Cethru! All's well with our house, and with the street before it?"
But, for answer, the old man only held his lanthorn up, so that in the ring of its pale light they saw some sight or other in the street. And his silence troubled them, one by one, for each had expected that he would reply:
"Aye, aye! All's well with your house, Sirs, and with the street before it!"
