The single tap of the drum warned him; the singing had ceased. And this bitter idealist, this preacher of the hollowness of the real, wondered where were the sable trappings of woe, the hideous envisagement of them that are condemned with mortuary symbols in garbs of painted flame to the stake, faggot, axe, and headsman. None of these were visible, and the gentle spirit of the prisoner became ruffled, alarmed. He expected violence but instead they offered churchly music. Restless, his nerves fretted, he asked himself the reason. He did not fear death, for he despised life; he had no earthly ties; his life's philosophy had been fittingly enunciated; and he knew that even though a terrible death overtook him his seed had fallen on ripe soil. As he was a descendant from some older system that denied the will to live, so would he in turn beget disciples who would be beaten, burned and reviled by the great foe to liberty—the foe that strangled it before Egypt's theocracy, aye! before the day of sun-worshippers invoking their round, burning god, riding naked in the blue. Baruch pondered these things, and had almost lost his grasp on time and space when something jarred his consciousness.

It was the tap of the drum, sombre, dull, hollow and threatening; he shivered as he heard its percussive note, and with a start remembered that the Dies Iræ had been chaunted in the same key. Once more he wondered.

A light touch on the shoulder brought him realization. He stood almost alone; the monks were gliding down the great Hall of the Oblates and disappearing through a low arched door, the sole opening in the huge apartment. One remained, a black friar, absolutely hooded.

Baruch followed him. The pair noiselessly traversed the wonderful hall with its canopies of light, its airy arches, massive groinings and bewildering blur of color and fragrance; the air was thick and grateful with incense. Exactly in the middle of the hall there rested on the floor a black shadow, a curiously shaped shadow. It was a life-sized crucifix which Baruch had not seen before. To it he was led by the black friar, who motioned him to the floor; then this unbelieving Jew and atheist laid himself humbly down, and with outstretched arms awaited his end.

In few rapid movements the prisoner was chained to the cross; and with a penetratingly sweet smile the friar gave him a silent blessing, while Baruch's eyes followed the dazzling tracery on the ceiling, and caught a glimpse of the golden, gleaming organ tubes above the Throne of Judgment.

The stillness was so profound that he heard the soft sighs of the candles, the forest of unnumbered candles; the room was windless. Again the singular fancy overtook him that the key of B ruled the song of the lights, and he stirred painfully because certain sounds irritated him, recalling as a child his vague rage at the Kol Nidrei, which was sung in the key of B at the synagogue.

He closed his eyes a moment and opened them with fright, for the drum sounded near his head, though he could not turn to see it. Suddenly he was encircled by ten monks and chaunting heard. Mendoza noticed the admirable monotone, the absolute, pitch, and then, with a leap of his heart, the key color B again; and the mode was major.

The hooded monks sang in Latin the Lord's Prayer. "Our Father," they solemnly intoned—"Our Father who art in Heaven; hallowed be thy name. Thy Kingdom come. Thy will be done on earth as it is in Heaven. Give us this day our daily bread. And forgive us our trespasses as we forgive those who trespass against us. And lead us not into temptation, but deliver us from evil. Amen."

Baruch tried to sleep. The rich voices lulled him into temporary rest; he seemed to have slept hours. But he knew this was impossible, for the monks were singing the Lord's Prayer when he awoke. He grew exasperated; why need they pray over him? Why did they not take him to his damp cell to rot or to be eaten by vermin? This blaze of light was unendurable; it penetrated his closed eyelids, painted burning visions on his brain, and the music—the accursed music—continued. Again the Lord's Prayer was solemnly intoned, and noticing the freshness of the voices he opened his eyes, counted ten cowled monks around him; and the key they sang was B, the mode major.

Another set, Baruch thought, as he remarked the stature of the singers, and sought oblivion. All that night and all next day he chased sleep, and the morning of the third day found him with half mad gaze, sleepless and frantic. When from deadly exhaustion he would half faint into stupor the hollow, sinister sound of the drum stunned his ears, while rich, churchly voices of men would intone "Pater noster, qui es in cœlis!" and always in the agonizing key of B.
