He remounted his horse as he approached the market-place, from which the town climbed up; but he found his way blocked, for 'twas market-day, and the great square, bordered with a colonnade that made an Eastern bazaar, was thickly planted with stalls, whose white canvas awnings struck a delicious note of coolness against the throbbing blue sky and the flaming costumes of the peasants come up from the environs. Through a corner of the _praca_ one saw poplars and elms and the fresh gleam of the river. The nasal hum of many voices sounded blithe and busy. At the bazaar entrance, where old women vended flowers and fruit, Gabriel reined in his horse.

"How happy these simple souls!" he mused. "How sure of their salvation! To count their beads and mutter their _Ave Marias_; 'tis all they need. Yon fisher, with his great gold ear-rings, who throws his nets and cuddles his Juanita and carouses with his mates, hath more to thank the saints for than miserable I, who, blessed with wealth, am cursed with loneliness, and loving my fellow-men, yet know they are but sheep. G.o.d's sheep, natheless, silly and deaf to the cry of their true shepherd, and misled by priestly wolves."

A cripple interrupted his reflections by a whining appeal. Gabriel shuddered with pity at the sight of his sores, and, giving him a piece of silver, lost himself in a new reverie on the mystery of suffering.

"Thine herbs sold out too!" cheerily grumbled a well-known voice, and, turning his head, Gabriel saw that the burly old gentleman addressing the wrinkled market-woman from the vantage-point of a mule's back was, indeed, Dom Diego de Balthasar, late professor of the logics at the University of Coimbra, and newly settled in Porto as a physician.

"Ay, indeed, ere noon!" the dried-up old dame mumbled. "All Porto seems hungry for bitter herbs to-day. But thus it happens sometimes about Eastertide, though I love not such salads myself."

"Naturally. They are good for the blood," laughed Dom Diego, as his eye caught Gabriel's. "And thou hast none, good dame."

There seemed almost a wink in the professorial eye, and the young horseman smiled in good-natured response to the physician's estimate of the jest.

"Then are the eaters sensible," he said.

"Ay, the only sensible people in Portugal," rejoined Dom Diego, changing his speech to Latin, but retaining his smile. "And the only good blood, Da Costa," he added, with what was now an unmistakable wink. But this time Gabriel failed to see the point.

"The only good blood?" he repeated. "Dost thou then hold with the Trappists that meat is an evil?"

A strange, startled look flashed across the physician's face, sweeping off its ruddy hue, and though his smile returned on the instant, it was as though forced back.

"In a measure," he replied. "Too much flesh generateth humors and distempers in the blood. Hence Holy Church hath ordained Lent. She is no friend to us physicians. _Adeos!_" and he ambled off on his mule, waving the young horseman a laughing farewell.

But Gabriel, skirting the market, rode up the steep streets troubled by a vague sense of a mystery, and later repeated the conversation to a friar at the college.

III.

A week later he heard in the town that Dom Diego de Balthasar had been arrested by the Inquisition for Judaism. The news brought him a more complex thrill than that shock of horror at the treacherous persistence of a pestilent heresy which it excited in the breast of his fellow-citizens. He recalled to mind now that there were thirty-four traces by which the bloodhounds of the Holy Office scented out the secret Jew, and that one of the tests ran: "If he celebrates the Pa.s.sover by eating bitter herbs and lettuces." But the shudder which the thought of the Jew had once caused him was, to his own surprise, replaced by a secret sympathy. In his slowly-matured, self-evolved scepticism, he had forgotten that a whole race had remained Protestant from the first, rejecting at any and every cost the corner-stone of the Christian scheme. And this race--he remembered suddenly with a leap of the heart and a strange tingling of the blood--had once been his own! The knowledge that had lurked in the background of consciousness, like the exiled memory of an ancient shame, sprang up, strong and a.s.sertive. The far-off shadowy figures of those base-born ancestors of his who had prayed in the ancient synagogues in the days before the Great Expulsion, shook off the mists of a hundred years and stood forth solid, heroic, appealing.

And then recalling the dearth of bitter herbs in the market-place on what he now understood was the eve of Pa.s.sover, he had a sudden intuition of a great secret brotherhood of the synagogue ramifying beneath all the outward life of Church and State; of a society honeycombed with Judaism that persisted tenaciously and eternally though persecution and expulsion, not in stray units, such as the Inquisition ferreted out, but in ineradicable communities. It was because the incautious physician had mistaken him for a member of the brotherhood of Israel that he had ventured upon his now transparent jests. "Good G.o.d!" thought Da Costa, sickening as he remembered the _auto-da-fe_ he had seen at Lisbon in his boyhood, when De la Asuncao, the Franciscan Jew monk, clothed in the Sanbenito, was solemnly burnt in the presence of the king, the queen, the court, and the mob. "What if 'twas my tale to Frei Jose that led to Dom Diego's arrest! But no, that were surely evidence too trivial, and ambiguous at the best." And he put the painful suspicion aside and hastened to shut himself up in his study, sending down an excuse to his mother and brother by Pedro, the black slave-boy.

In the beautiful house on the hilltop, built by Gabriel's grandfather, and adorned with fine panelings and mosaics of many-colored woods from the Brazils, this study, secluded by its position at the head of the n.o.ble staircase, was not the least beautiful room. The floor and the walls were of rich-hued tiles, the arched ceiling was ribbed with polished woods to look like the scooped-out interior of a half-orange.

Costly hangings m.u.f.fled the noise of the outer world, and large shutters excluded, when necessary, the glare of the sun. The rays of Reason alone could not be shut out, and in this haunt of peace the young Catholic had known his bitterest hours of unrest. Here he now cast himself feverishly upon the perusal of the Old Testament, neglected by him, as by the Church.

"This book, at least, must be true," ran his tumultuous thoughts. "For this Testament do both creeds revere that wrangle over the later." He had a Latin text, and first he turned to the fifty-third chapter of Isaiah, and, reading it critically, he seemed to see that all these pa.s.sages of prediction he had taken on trust as prognostications of a Redeemer might prophesy quite other and more intelligible things. And long past midnight he read among the Prophets, with flushed cheek and sparkling eye, as one drunk with new wine. What sublime truths, what aspirations after peace and justice, what trumpet-calls to righteousness!

He thrilled to the cry of Amos: "Take thou away from me the noise of thy songs, for I will not hear the melody of thy viols. But let judgment run down as waters, and righteousness as a mighty stream."

And to the question of Micah: "What doth the Lord require of thee but to do justly and to love mercy and to walk humbly with thy G.o.d?" Ay, justice and mercy and humbleness--not paternosters and penances. He was melted to tears, he was exalted to the stars.

He turned to the Pentateuch and to the Laws of Moses, to the tender ordinances for the poor, the stranger, the beast. "Thou shalt love thy neighbor as thyself." "Thou shalt be unto me a holy people."

Why had his ancestors cut themselves off from this great people, whose creed was once so sublime and so simple? There had reached down to him some vague sense of the nameless tragedies of the Great Expulsion when these stiff-necked heretics were confronted with the choice of expatriation or conversion; but now he searched his book-shelves eagerly for some chronicle of those days of Torquemada. The native historians had little, but that little filled his imagination with horrid images of that second Exodus--famine, the plague, robbery, slaughter, the violation of virgins.

And all on account of the pertinacious ambition of a Portuguese king to rule Spain through an alliance with a Spanish princess--an ambition as pertinaciously foiled by the irony of history. No, they were not without excuse, those ancestors of his who had been left behind clinging to the Church. Could they have been genuine converts, these Marranos, or New Christians? he asked himself. Well, whatever his great-grandfathers had felt, his father's faith had been ardent enough, of that he could not doubt. He recalled the long years of ritual; childish memories of paternal pieties. No, the secret conspiracy had not embraced the Da Costa household. And he would fain believe that his more distant progenitors, too, had not been hypocrites; for aught he knew they had gone over to the Church even before the Expulsion; at any rate he was glad to have no evidence for an ancestry of deceit. None of the Da Costas had been cowards, thank Heaven! And he--he was no coward, he told himself.

IV

In the morning, though only a few hours of sleep had intervened, the enthusiasm of the night had somewhat subsided. "Whence came the inspiration of Moses?" flew up to his mind almost as soon as he opened his eyes on the sunlit world. He threw open the protrusive cas.e.m.e.nt of his bedroom to the balmy air, tinged with a whiff of salt, and gazed pensively at the white town rambling down towards the shining river.

Had G.o.d indeed revealed Himself on Mount Sinai? But this fresh doubt was banished by the renewed suspicion which, after having disturbed his dreams in nebulous distortions, sprang up in daylight clearness.

It was his babbling about Dom Diego that had ruined the genial old physician. After days of gathering uneasiness, being unable to gain any satisfaction from the friar, he sought the secretary of the Inquisition in his bureau at a monastery of the Dominicans. The secretary rubbed his hands at the sight of the speechful face. "Aha!

What new foxes hast thou scented?" The greeting stung like a stab.

"None," he replied, with a tremor in his speech and in his limbs. "I did but desire to learn if I am to blame for Dom Diego's arrest."

"To blame?" and the secretary looked askance at him. "Say, rather, to praise."

"Nay, to blame," repeated Gabriel staunchly. "Mayhap I mistook or misrendered his conversation. 'Tis scant evidence to imprison a man on. I trust ye have found more."

"Ay, thou didst but set Frei Jose on the track. We did not even trouble thee to appear before the Qualifiers."

"And he is, indeed, a Jew!"

"A Hebrew of Hebrews, by his stiff-neckedness. But 'twas not quite proven; the fox is a cunning beast. Already he hath had the three 'first audiences,' but he will not confess and be made a Penitent.

This morning we try other means."

"Torture?" said Gabriel, paling. The secretary nodded.

"But if he is innocent."

"No fear of that; he will confess at the first twinge. Come, unknit thy brow. Wouldst make sure thou hast served Heaven? Thou shalt hear his confession--as a reward for thy zeal."

"He will deem I have come to gloat."

"Here is a mask for thee."

Gabriel took it hesitatingly, repelled, but more strongly fascinated, and after a feverish half-hour of waiting he found himself with the secretary, the judge of the Inquisition, the surgeon, and another masked man in an underground vault faintly lit by hanging lamps. On one side were the ma.s.sive doors studded with rusty k.n.o.bs, of airless cells; on the rough, spider-webbed wall opposite, against which leaned an iron ladder, were fixed iron rings at varying heights. A thumbscrew stood in the corner, and in the centre was a small writing-table, at which the judge seated himself.

The secretary unlocked a dungeon door, and through the holes of his mask Gabriel had a glimpse of the despondent figure of the burly physician crouching in a cell nigh too narrow for turning room.

"Stand forth, Dom Abraham de Balthasar!" said the judge, ostentatiously referring to a paper.

The physician blinked his eyes at the increased light, but did not budge.

"My name is Dom Diego," he said.

"Thy baptismal name imports no more to us than to thee. Perchance I should have said Dom Isaac. Stand forth!"

The physician straightened himself sullenly. "A pretty treatment for a loyal son of Holy Church who hath served his Most Faithful and Catholic Sovereign at the University," he grumbled. "Who accuses me of Judaism? Confront me with the rogue!"

"'Tis against our law," said the secretary.

"Let me hear the specific charges. Read me the counts."

"In the audience-chamber. Anon."

"Confess! confess!" snapped the judge testily.
