This by no means suited the views of the Orange faction. The life of the two brothers being a constant obstacle to their plans, they changed their tactics, and tried to obtain by calumny what they had not been able to effect by the aid of the poniard.
How rarely does it happen that, in the right moment, a great man is found to head the execution of vast and noble designs; and for that reason, when such a providential concurrence of circumstances does occur, history is prompt to record the name of the chosen one, and to hold him up to the admiration of posterity. But when Satan interposes in human affairs to cast a shadow upon some happy existence, or to overthrow a kingdom, it seldom happens that he does not find at his side some miserable tool, in whose ear he has but to whisper a word to set him at once about his task.
The wretched tool who was at hand to be the agent of this dastardly plot was one Tyckelaer whom we have already mentioned, a surgeon by profession.
He lodged an information against Cornelius de Witt, setting forth that the warden--who, as he had shown by the letters added to his signature, was fuming at the repeal of the Perpetual Edict--had, from hatred against William of Orange, hired an assassin to deliver the new Republic of its new Stadtholder; and he, Tyckelaer was the person thus chosen; but that, horrified at the bare idea of the act which he was asked to perpetrate, he had preferred rather to reveal the crime than to commit it.
This disclosure was, indeed, well calculated to call forth a furious outbreak among the Orange faction. The Attorney General caused, on the 16th of August, 1672, Cornelius de Witt to be arrested; and the noble brother of John de Witt had, like the vilest criminal, to undergo, in one of the apartments of the town prison, the preparatory degrees of torture, by means of which his judges expected to force from him the confession of his alleged plot against William of Orange.
But Cornelius was not only possessed of a great mind, but also of a great heart. He belonged to that race of martyrs who, indissolubly wedded to their political convictions as their ancestors were to their faith, are able to smile on pain: while being stretched on the rack, he recited with a firm voice, and scanning the lines according to measure, the first strophe of the "Justum ac tenacem" of Horace, and, making no confession, tired not only the strength, but even the fanaticism, of his executioners.
