Omobono had drawn on a pair of well-greased raw-hide boots that came half-way up his thin legs, and had wrapped himself in his big brown cloak before going out. On his smooth grey head he wore a soft felt hat, the brim turned up round the crown at the back but pulled out to a long point in front, and he carried a tough cornel stick in his right hand. He had been careful to leave in the strong box the purse that contained money belonging to his employer, and had but a few small coins of his own in his wallet to pay a ferryman if he should need one, or to give to a hungry beggar. Like most men who have failed to make money Omobono was very sorry for poor people, and did not believe that all beggars could be rich if they would work. But he was poor himself, and his charity was of the humble kind.

There was a fairly broad street behind Carlo Zeno's house, and here the early spring sun had dried the mud to something like a solid surface; but Omobono followed this thoroughfare only for a little distance, and then turned into a narrow and filthy lane that led to other lanes, and to others still beyond, all crowded with humanity, all dark and muddy, all foul with garbage, all reeking with the overpowering smell of Eastern cooking made up of garlic, frying onions, sour cream, oil of sesame, and roasting mutton where there were Jews or Mohammedans, or fried fish where Christians lived, since it was Friday.

The small wooden houses, black with smoke and the dampness of the past winter, overhung the way so that the opposite balconies of the second stories almost touched each other. Had the buildings been higher, scarcely any light at all would have reached the lower windows; as it was, a man with good eyes might just see to read at noon if he were not too far within.

Omobono evidently knew his way well enough, for he did not pause as he threaded the labyrinth, and only now and then glanced up at certain dingy signs that hung from the crazy wooden balconies, or from wooden arms that stuck out here and there like gallows from the walls. As he walked, he was chiefly occupied in not running against the people he met, and in not stepping upon the half-naked children that squirmed and squalled in the mud before every doorstep. For there were children everywhere, children and dirt, dirt and children, all of much the same colour in those dusky lanes. Near almost every open door the slatternly mother stirred a dark mess of some sort over a little earthen pan of coals, or toasted gobbets of fat mutton on a black iron fork, or fried some wretched fish in boiling oil. The Christian women were by far the dirtiest, and their children were the least healthy and the most neglected, for many of the little creatures had not a stitch of clothing on them. Most decent were the Mohammedans; they had already the bearing and the self-respect of the conquering race, and they treated their Greek and Bokharian neighbours with silent contempt. Did not Sultan Amurad, over there on the Asian shore, make and unmake these miserable little Greek emperors as he pleased? If he chose could he not take Constantinople and turn a stream of Christian blood into the Golden Horn that would redden the Sea of Marmora as far as Antigone and Prinkipo?

Omobono went on and on, picking his way as he might, and little noticed by the people. He was not by any means in the poorest quarter of the city, and no one begged of him as he went by. If he thought of anything except of not setting his booted foot down on some child's sprawling leg or arm, he thanked heaven and the saints that he had been born a Venetian, and had been washed and sent to school like a Christian boy when he was little instead of having first seen the light, or what passed for light, in a back street of Constantinople.

He turned another corner, entered a lane even narrower than those he had yet traversed, but almost deserted, and much less dark because one side of it was occupied by a wall not more than ten feet high, in which only one small door was to be seen. Along the top of the masonry all sorts of sharp bits of rusty iron and a quantity of broken crockery were set in mortar with the evident intention of discouraging any attempt to climb over, either from within or from without. The door itself was in good repair, and had been recently coated with tar and sharp sand by way of preserving it against the damp. A well-worn horizontal slit an inch long, and an upright one a foot higher up, showed that it had two separate Persian locks into which keys were often thrust.

Omobono rapped on the tarred wood with the iron-shod end of his stick and listened. He could hear a number of girls' voices chattering, and one was singing softly in a language he did not understand. He knocked again, a moment later the voices were suddenly silent, and he heard the clacking of heavy slippers on wet flags as some one came to open.

'Who knocks?' asked a deep and harsh female voice from within, in the Greek tongue but with a thick accent.

'A Venetian who has business with the worthy Karaboghazji,' answered Omobono in a conciliatory tone.

'Which Karaboghazji?' enquired the voice suspiciously.

'Rustan,' explained Omobono mildly.

From his voice, the woman probably judged that if he had come with any nefarious purpose she was more than a match for him. The door opened after some rattling and creaking of locks, and Omobono started in spite of himself. She was indeed a match for him, or for any other man who was likely to knock at the door. It was no wonder that the Venetian secretary drew back and hesitated before he spoke again.

The woman was a huge red-haired negress in yellow, fully six feet tall in her heelless slippers, and her black arms, bare above the elbow, were as sinewy and muscular as any fisherman's or porter's. Her thick lips were parted in a sort of savage grin that showed two rows of teeth as sharp and white as a shark's; her hair must have been just dyed that day, for it was as red as flame to the very roots, and it stood out almost straight from her shiny black forehead and temples; as she rather contemptuously scrutinised Omobono from head to foot the whites of her coal-black eyes gleamed in a way that was positively terrifying. She wore wide Greek trousers of blue cotton, gathered at the ankle, and a wadded coat of yellow, that hung down below her knees in loose folds, like a sort of skirt, but fitted tightly over her tremendous shoulders. This garment was closely girded round her ample waist by a red sash, in which she carried her armoury, consisting of a serviceable Arab knife with a bone hilt and brass sheath, and a small whip made of a broad flat thong of hippopotamus hide with a short oak stock.

This terrific apparition stood in the little vestibule holding the door open and grinning at Omobono. She had closed another door behind her before opening the outer one, for the slave-dealer's establishment was evidently managed with a view to the safety of his merchandise.

'And what do you want of Rustan Karaboghazji at this time of the afternoon?' enquired the negress. 'Who are you?'

'I am only a clerk,' answered Omobono in a deprecating tone, and shrinking a little under his cloak, as the awful virago thrust her head forward. 'I am the clerk of Messer Carlo Zeno, a rich Venetian merchant, who sends a message by me to your master——'

'My master!' interrupted the black woman, with a scornful laugh. 'My master, indeed!'

'I—I supposed——' faltered Omobono apologetically.

The negress moved a little and rested one huge hand on her hip, while she slipped the other slowly up the door-post till it was above her head. In this attitude she looked gigantic.

'You mean my husband,' she said, showing all her teeth. 'Rustan Karaboghazji is my husband. Do you understand?'

'Yes, KokÓna—I—I mean KyrÍa—yes, certainly! I should have known at once that you were the mistress of the house if you had not condescended to open the door yourself, KyrÍa.'

'And what would become of the cattle,' enquired the negress with a backward toss of her head towards the yard behind her, 'if the stable door were in charge of a slave? If your master—' she dwelt on the two words contemptuously—'wishes to buy of us, he will have to come here and choose for himself.'

'No, no!' answered Omobono hastily. 'It is another matter. I think it is a commission for a friend. It is something very especial. That is why I beg to be allowed to speak with the Kyrios, your husband.'

The black woman had listened attentively.

'At this hour,' she said after a moment's thought, 'Rustan is at his devotions.'

'I would not interrupt them for the world,' protested Omobono. 'I can wait——'

'No. You will probably find him at the church of Saint Sergius and Saint Bacchus. If he is not there, ask the sacristan where he is. My husband is a very devout man; the sacristan knows him well.'

'I hope,' said Omobono, whose curiosity scented a mystery, 'that the sacristan will not take me for an importunate stranger and send me on a fool's errand. If the KyrÍa would give me some sign by which the sacristan may know that I came from her——'

Omobono paused on this suggestion, hoping for a favourable answer. Again the big woman waited a moment before speaking.

'Ask the sacristan to direct you to find Rustan Karaboghazji, by four toes and by five toes,' she said at last. 'He will certainly tell you the truth if you ask him in that way.'

'By four toes and by five toes,' repeated Omobono. 'I cannot forget that. I thank you, KyrÍa Karaboghazji, and I wish you a good day.'

The negress nodded and showed her teeth but said nothing more, drew back and shut the door without waiting any longer. Omobono stood still a moment, listened to the slapping of the heavy slippers on the wet flags within, and then went away down the almost deserted lane, wondering much at the taste of the Bokharian merchant in marrying an African giantess. But soon his natural curiosity began to occupy itself more actively with the hidden meaning of the password given him by Rustan's wife; and, meditating on this problem, he made his way through the heart of the city, traversing many narrow and tortuous streets, till he suddenly emerged into a broad highway where marble buildings gleamed in the late afternoon sunshine, and richly dressed Greeks lounged in the wide exedrÆ and stately porticoes, discussing the affairs of the Empire in general and their neighbours' most particularly.

Omobono trudged along, past the corner of the wide Forum of Theodosius, once the centre of the city's teeming life, but now given over to the tanners and leather-dressers, for one end of it was used as a slaughterhouse and the hides had not to be dragged far to be cured; he walked on quickly, keeping to the left, and was soon in narrow streets again, where afterwards the Grand Bazaar was built, and where even in those days the Persian merchants and the jewellers, the dealers in fine carpets and Eastern merchandise, the perfumers, the Egyptian goldsmiths and the Bokharian money-changers had their homes and the headquarters of their business. Here Omobono exchanged greetings now and then with men of all nationalities except Genoese, and very few of these last were to be seen, for they kept to their own quarter beyond the Golden Horn, in Pera. But Omobono would not stop to talk, and the streets were clean here, and well kept, and the children were not to be seen, so that he could walk quickly, without picking his way.

On still, and farther on; through the almost classic Forum of Constantine, past the hill on which the bronze-bound porphyry column still stands, and down on the other side, keeping the Hippodrome on his left and diving into the Bokharian quarter, as different from the last through which he had come, as that had been from those he had passed before. For then, as now, Constantinople was a patchwork of divers nations and languages and customs, and their quarters were like distinct towns,—some filthy, noisy and unhealthy, some rich and stately, some quiet and poor, some asleep all day and riotous all night, others silent as sleep itself from nightfall till dawn, and noisy all day with the hum of business or the ceaseless hammering clang and clatter of workmen's tools.

Before Omobono emerged upon the little square which then surrounded the churches of Saints Sergius and Bacchus and of Saints Peter and Paul—the latter is now destroyed—he heartily wished that he had hired a horse and man at one of the street corners; but he forgot his weariness when his destination was reached, and he saw a little bandy-legged sacristan in an absurdly short cassock of shabby black and purple cloth, leaning against one of the columns of the portico.

Omobono ascended the broad steps that led up from the level of the street, as though he were going in, but just as he was close to the sacristan he stopped, as if without any premeditation, and made a gesture of salutation, smiling in a friendly way.

'Praised be our Lord,' he said, in the Greek manner.

'Our Lord be praised. Amen,' answered the sacristan indifferently, for it was the custom to do so.

'Could you inform me,' proceeded the Venetian clerk, 'whether that good man Kyrios Rustan Karaboghazji is now in the church at his devotions?'

The sacristan had a perfectly round head with a pair of very small round eyes; moreover, his snub nose was quite round at the end. He now pursed out his lips and made his mouth round, too, as if he were going to whistle. Intentionally or unintentionally, he made himself look like an idiot, and slowly wagged his bullet head as if he did not understand.

'The church is open,' he said, at last. 'You may see,'

Omobono now applauded himself for having asked and obtained a password, but he meant to be cautious in using it.

'Thank you,' he said politely, and he went on, into the church.

The sun was low and cast a rich light through the open door, full upon the grating and closed gate of the sanctuary, and the gilt and burnished bars reflected and diffused the warm rays, like a glory before the unseen high altar. Omobono glanced quickly to the right and left as he passed between the pillars, but he saw no one. Farther on, before him and under the wide dome, two women in brown were at their prayers, the one kneeling, the other prostrate, in Eastern fashion, her forehead resting on the marble pavement. There was no man in sight.

Omobono chose a clean spot, hitched up his cloak in front and knelt upon one knee. He crossed himself and said a little prayer.

'O Lord,' he prayed, 'grant wealth and honour to the Most Serene Republic and give Venice the victory over the Genoese. Bless Messer Carlo Zeno, O Lord, and preserve him from sudden death. Send bread to the poor. Give Omobono strength to resist curiosity. For ever and ever. Amen.'

It was not a very eloquent little prayer and it lacked the set forms of invocation and doxology which devout persons use; but Omobono had made it up for himself long ago, and said it every day at least once, for it precisely expressed what he sincerely wished and intended to ask with due humility; and he was a good man, in spite of his besetting fault, and believed that what he asked would be granted. As yet, Venice had not triumphed over those unspeakable dogs of Genoese, though the day of glory was much nearer than even the Venetians dared to hope. But so far Carlo Zeno had been preserved from sudden death in spite of his manifest tendency to break his neck for any whim; for the rest, Omobono had more than once been the means of saving poor people from starvation, though at some risk of it to himself, poor man; and as for his curiosity, he had at least kept it so far in bounds as never to read his master's letters until his master had opened them himself, which was something for Omobono to be grateful for. On the whole, he judged that his small prayer was not unacceptable, and he used it every day.

He knelt a moment after he had finished it, partly because he was a little ashamed of its being very short though he never could think of anything to add to it, and he did not wish people to think that he was irreverent and gabbled over a prayer merely as a form; for he was very sensitive about such things, being a shy man. And partly he remained on his knees a little longer because the gilded grating was very handsome in the light of the setting sun, and reminded him of the grating in Saint Mark's, and that naturally made him think of heaven. But presently he rose and went out.

The sacristan was still standing by the same pillar.

'Kyrios Rustan is not in the church,' said Omobono, stopping again.

Once more the sacristan seemed to be about to purse his lips into a circle, and to put on an air of blank stupidity, and the clerk saw that the time had come to use the password.

'I must see him,' he said, dropping his voice, but speaking very distinctly. 'I beg you to direct me by four toes and five toes, so that I may find him.'

The sacristan's face and manner changed at once. His small eyes were suddenly full of intelligence, his mouth expanded in a friendly smile, and his snub nose seemed to draw itself to a point like the muzzle of a hound on a scent.

'Why did you not say that at once?' he asked. 'Rustan left the church a quarter of an hour before you came, but he is not far away. Do you see the entrance to the lane down there?'

He pointed towards the place.

'Yes,' said Omobono, 'by the corner.'

'Yes. Go into that lane. Take the first turn to the left, and then the second to the right again. Before you have gone far you will find Rustan walking up and down.'

'Walking up and down?' repeated Omobono, surprised that the Bokharian should select for his afternoon stroll such a place as one might expect to find in the direction indicated.

'Yes.' The sacristan grinned and winked at the Venetian clerk in a knowing way. 'He is a devout man. When he has said his prayers he walks up and down in that little lane.'

The man laughed audibly, but immediately looked behind him to see whether any one coming from within the church had heard him, for he considered himself a clerical character. Omobono thanked him politely.

'It is nothing,' answered the sacristan. 'A mere direction—what is it? If I had asked you for your purse and cloak by four toes and five toes, I am quite sure that you would have given me both.'

'Of course,' replied Omobono nervously, seeing that the reply was evidently expected of him. 'Of course I would. And so, good-day, my friend.'

'And good-day to you, friend,' returned the sacristan.

The clerk went away, devoutly hoping that no unknown person would suddenly accost him and demand of him his cloak in the name of four toes and five toes, and he wondered what in the world he should do if such a thing happened to him. He was quite sure that he should be unable to hide the fact that he knew the magic formula, for he had never been very good at deception; and if the words could procure such instant obedience from such a disagreeable person as the sacristan had at first seemed to be, some dreadful penalty was probably the portion of those who disobeyed the mandate.

Thus reflecting, and by no means easy in his mind, the clerk crossed the square and entered the lane. He had supposed that it led to a continuation of the Bokharian quarter, but he at once saw his mistake. Even now a man may live for years in Constantinople and yet be far from knowing every corner of it, and Omobono found himself in a part of the city which he had never seen. It was in ruins, and yet it was inhabited. Few of the houses had doors, hardly any window had a shutter, and as he passed, he saw that in many lower rooms the light fell from above, through a fallen floor and a broken roof above it.

Yet in every ruined dwelling, and almost at every door, there was some one, and all were frightful to see; all were in rags that hardly clung together, and some could scarcely cover themselves modestly; one was blind, another had no arms or no legs, another was devoured by hideous disease—many were mere bundles of bones in scanty rags, and stretched out filthy skeleton hands for alms as the decently dressed clerk came near. Omobono stood still for a moment when he realised that he was in the beggars' quarter, where more than half the dying paupers of the great city took refuge amidst houses ruined and burnt long ago when the Crusaders had sacked Constantinople, and never more than half repaired since then.

The clerk stood still, for the sight of so much misery hurt him, and it hurt him still more to think that he had but very few small coins in his wallet. The poor creatures should have them all, one by one, but there would be few indeed for so many.

He was talking with an old beggar woman.
