And lo! One sweep of the brush, and the picture is changed.

Ten minutes . . . less . . . and the whole course of the world's history is altered. No sooner has St. Just mounted the tribune than Tallien jumps to his feet. His voice, usually meek and cultured, rises in a harsh crescendo, until it drowns that of the younger orator.

"Citizens," he exclaims, "I ask for truth! Let us tear aside the curtain behind which lurk concealed the real conspirators and the traitors!"

"Yes, yes! Truth! Let us have the truth!" One hundred voices—not forty—have raised the echo.

The mutiny is on the verge of becoming open revolt, is that already, perhaps. It is like a spark fallen—who knows where?—into a powder magazine. Robespierre feels it, sees the spark. He knows that one movement, one word, one plunge into that magazine, foredoomed though it be to destruction, one stamp with a sure foot, may yet quench the spark, may yet smother the mutiny. He rushes to the tribune, tries to mount. But Tallien has forestalled him, elbows him out of the way, and turns to the seven hundred, with a cry that rings far beyond the Hall, out into the streets.

"Citizens!" he thunders in his turn. "I begged of you just now to tear aside the curtains behind which lurk the traitors. Well, the curtain is already rent. And if you dare not strike at the tyrant now, then 'tis I who will dare!" And from beneath his coat he draws a dagger and raises it above his head. "And I will plunge this into his heart," he cries, "if you have not the courage to smite!"

His words, that gleaming bit of steel, fan the spark into a flame. Within a few seconds, seven hundred voices are shouting, "Down with the tyrant!" Arms are waving, hands gesticulate wildly, excitedly. Only a very few shout, "Behold the dagger of Brutus!" All the others retort with "Tyranny!" and "Conspiracy!" and with cries of "Vive la Liberté!"

At this hour all is confusion and deafening uproar. In vain Robespierre tries to speak. He demands to speak. He hurls insults, anathema, upon the President, who relentlessly refuses him speech and jingles his bell against him.

"President of Assassins," the falling tyrant cries, "I demand speech of thee!"

But the bell goes jingling on, and Robespierre, choked with rage and terror, "turns blue" we are told, and his hand goes up to his throat.
