One of them, who bore the character of a profound observer, laid down as his opinion that this young man, so phlegmatic in appearance, must in reality be very dangerous, as under this icy exterior he was sure to conceal an ardent desire to avenge his friends, the De Witts.
Another observed that the love of tulips agreed perfectly well with that of politics, and that it was proved in history that many very dangerous men were engaged in gardening, just as if it had been their profession, whilst really they occupied themselves with perfectly different concerns; witness Tarquin the Elder, who grew poppies at Gabii, and the Great Conde, who watered his carnations at the dungeon of Vincennes at the very moment when the former meditated his return to Rome, and the latter his escape from prison.
The judge summed up with the following dilemma:-"Either Cornelius van Baerle is a great lover of tulips, or a great lover of politics; in either case, he has told us a falsehood; first, because his having occupied himself with politics is proved by the letters which were found at his house; and secondly, because his having occupied himself with tulips is proved by the bulbs which leave no doubt of the fact. And herein lies the enormity of the case. As Cornelius van Baerle was concerned in the growing of tulips and in the pursuit of politics at one and the same time, the prisoner is of hybrid character, of an amphibious organisation, working with equal ardour at politics and at tulips, which proves him to belong to the class of men most dangerous to public tranquillity, and shows a certain, or rather a complete, analogy between his character and that of those master minds of which Tarquin the Elder and the Great Conde have been felicitously quoted as examples."
The upshot of all these reasonings was, that his Highness the Prince Stadtholder of Holland would feel infinitely obliged to the magistracy of the Hague if they simplified for him the government of the Seven Provinces by destroying even the least germ of conspiracy against his authority.
This argument capped all the others, and, in order so much the more effectually to destroy the germ of conspiracy, sentence of death was unanimously pronounced against Cornelius van Baerle, as being arraigned, and convicted, for having, under the innocent appearance of a tulip-fancier, participated in the detestable intrigues and abominable plots of the brothers De Witt against Dutch nationality and in their secret relations with their French enemy.
A supplementary clause was tacked to the sentence, to the effect that "the aforesaid Cornelius van Baerle should be led from the prison of the Buytenhof to the scaffold in the yard of the same name, where the public executioner would cut off his head."
