That such was actually the case is proved by De Thou, who relates an extraordinary speech made by the King at the Louvre, in 1599, on the occasion of the promulgation of the Edict of Nantes, to the deputies of the Parliament of Paris, in the course of which he declared that, twenty-six years previously, when he was residing at the Court of Charles IX, he was about to cast the dice with Henri de Lorraine, Duc de Guise, his relative, amid a large circle of nobles, when at the instant in which they were prepared to commence their game drops of blood appeared upon the table, which were renewed without any apparent agency as fast as they were wiped away. Each party carefully ascertained that it could not proceed from any of the individuals present; and the phenomenon was so frequently repeated that Henry, as he averred, at once amazed and disturbed, declined to persevere in the pastime, considering the circumstance as an evil omen.[154] Whatever may be the opinion of the reader as to the actual cause of this apparent prodigy, it is at least certain that it was verified by subsequent events, as well as the extraordinary and multiplied prophecy that the King himself would meet his death in a coach. Under these circumstances, combined with the almost universal credulity of the age and nation which he governed, it is scarcely matter of surprise that Henri IV, on so momentous an occasion as the birth of his son, should have sought, even while he feigned to disregard the result, to learn the after-destiny of the royal infant; and accordingly, a few days subsequently, he commanded M. de la Rivière,[155] who publicly professed the science of judicial astrology, to draw the horoscope of the Dauphin with all the accuracy of which the operation was susceptible. The command was answered by an assurance from La Rivière that the work was already in progress; but as another week passed by without any communication from the seer, Henry became impatient, and again summoned him to his presence in order to inquire the cause of the delay. "Sire," replied La Rivière, "I have abandoned the undertaking, as I am reluctant to sport with a science whose secrets I have partially forgotten, and which I have, moreover, frequently found defective." "I am not to be deceived by so idle a pretext," said the King, who readily detected that the alleged excuse was a mere subterfuge; "you have no such scruples, but you have resolved not to reveal to me what you have ascertained, lest I should discover the fallacy of your pretended knowledge or be angered by your prediction. Whatever may be the cause of your hesitation, however, I am resolved that you shall speak; and I command you, upon pain of my displeasure, to do so truthfully."
