And now this last experiment, so bold that he had almost shrunk from trying it, which had resulted in an unbroken series of successes in the midst of an epidemic with an enormous mortality! Once again he was a doctor and nothing more. With redoubled zeal he followed every case, scarcely for a minute did he leave his patient's side, and with increasing excitement he watched every symptom, every detail, with his former scepticism—and yet the fact remained, for a whole week not a single fatal case!

He had almost forgotten that Don Dionisio and the Madonna del Buon Cammino followed his footsteps—he had forgotten them as he had forgotten himself. Now and then his vacant eyes would fall upon the unconscious assistant at his side, and he felt glad that he had been able to give the old man a share in his success. Don Dionisio seemed to need no more rest than the doctor, day and night he was going about with his Madonna. His face shone with ecstasy, and he enjoyed to the full his short happiness.

The Madonna del Buon Cammino was now clothed in a flame-coloured silken mantle, a diadem of showy glass beads encircled her brow, and round her neck, strung upon a cord, hung numbers of rings and gold ear-rings. Night and day votive candles were lighted in her chapel, and on the walls, so naked before, hung ex votos of all possible kinds, thank-offerings for deliverance from sickness and death. The chapel was always full of people, praying fervently on their knees for help from that mighty Madonna who had performed so many miracles, and who stretched out her protecting hand over the street. For, to his amazement, the doctor had heard Don Dionisio prophesy that as long as the lights burned in the chapel of the Madonna del Buon Cammino, the cholera would never dare to approach her street.

It was now that the poor people of Naples were to suffer their deepest misery, that the infection, swift as fire, broke out all over the alleys and slums of the four poor quarters. It was now that people fell down in the street as if they had been struck by lightning; that the dying and dead lay side by side in almost every house; that the omnibuses of Portici, filled with the day's death-harvest, were driven every evening up to the Campo Santo dei Colerosi,[41] where over a thousand corpses every night filled the enormous grave. It was now that trembling hands broke down the walls with which modern times had hidden the old shrines at the street corners, that the people in wild fury stormed the Duomo to force the priests to carry San Gennaro himself down to their alleys. It was now that anxiety reached the borders of frenzy, that despair began to howl like rage, that from trembling lips prayers and curses fell in alternating confusion, that knives gleamed in hands which just before had convulsively grasped rosary and crucifix.

The doctor and his friend went on their way as before, undisturbed by the increasing terrors which surrounded them. And wherever they went Death gave way before them. The doctor needed all his self-control to enable him still to maintain his doubts, and before his eyes he saw like a mirage the goal which his daring dreams already reached. As for Don Dionisio, no questioning doubt had ever awakened his slumbering freedom of thought, and long ago the doctor had given up all attempts to restrain the old fellow's joyous conviction of his victory.

The epidemic had now reached its highest point, almost every house in the quarter was infected, and still Don Dionisio's prophecy held good, for not a single case had occurred in the street of the Madonna del Buon Cammino.

The doctor had been told by a commare that in one of the bassi in Orto del Conte lay a dying woman, and that her husband had been avvelenato[42] in the hospital the day before. He went there the same evening, but it was with great difficulty that he succeeded in getting through the hostile crowd which had assembled in front of the infected house. He heard that the husband had been removed almost by force to the hospital, that he had there died, and that when, a couple of hours afterwards, they had tried to remove his wife too, who had been attacked in the night, the people had opposed it, a carabiniere had been stabbed, and the others had had to save their lives by flight. As usual, the unfortunate doctors bore the blame of all the evil, and he heard all around him in the crowd the well-known epithets of "Ammazzacane!" "Assassino!"[43] "Avvelenatore!"[44] After several fruitless efforts to gain their confidence and make friends with them, he had no choice but to give up all attempts of helping the sick woman and to wait till Don Dionisio came. As soon as he entered the room the attention of every one was at once fixed upon him and his Madonna, and they all fell on their knees and prayed fervently, without caring in the least about either the patient or the doctor. The woman was in Stadium algidum,[45] but her pulse was still perceptible. Strong in the confidence of his previous successes, the doctor went to work. He had hardly finished before the heart began to flag. Just as Don Dionisio with triumphant voice announced that the miracle was done, the death-agony began, and it was with the greatest difficulty that the doctor could keep up the action of the heart until the Madonna del Buon Cammino had left the house, followed by the crowd outside in solemn procession. Shortly afterwards the doctor slipped out of the house like a thief, and ran for his life to the corner of the Via del Duomo, where he knew he would be in safety.

The same night three of his patients died. He did his utmost to prevent Don Dionisio accompanying him the following day, but in vain. Every one of the sick he visited and treated that day died under his eyes.

The wings which had borne him during those days had fallen from his shoulders, and dead tired he wandered home in the evening with Don Dionisio at his side. They said good-night to each other in front of the chapel of the Madonna del Buon Cammino, and in the flickering light of the lamp before her shrine the doctor saw a deathly pallor spread over his friend's face. The old man tottered and fell, with the Madonna in his arms. The doctor carried him into the chapel and laid him upon the straw bed where he slept, in a corner behind a curtain. He placed the Madonna del Buon Cammino carefully on her stand, and poured oil for the night into the little lamp which burned over her head. Don Dionisio motioned with his hand to be moved nearer, and the doctor dragged his bed forward to the pedestal of the image. "Come è bella, come è simpatica!" said he, with feeble voice. He lay there quite motionless and silent, with his eyes intently fixed upon his beloved Madonna. The doctor sat all night long by his side, whilst his strength diminished more and more and he slowly grew cold. One votive candle after another flickered and went out, and the shadows fell deeper and deeper in the chapel of the Madonna del Buon Cammino. Then it became all dark, and only the little oil-lamp as of old spread its trembling light over the pale waxen image with the impassive smile upon her rigid features.

The next day the doctor fainted in the street, and was picked up and taken to the Cholera Hospital. And, indomitable as fate, death swept over the street of the Madonna del Buon Cammino, over Vicolo del Monaco. For it was Vicolo del Monaco—that name which filled Naples with terror, and which, through the newspapers, was known to the whole world as the place where the cholera raged in its fiercest form.[46]
