Many other circumstances contributed to confirm Catherine's belief in the occult sciences. On the eve of the tournament where Henri II. was mortally wounded, Catherine saw the fatal thrust in a dream. Her astrological council, consisting of Nostradamus and the two Ruggieri, had foretold the King's death. History has recorded Catherine's earnest entreaties that he should not enter the lists. The prognostic, and the dream begotten of the prognostic, were verified. The chronicles of the time relate another and not less strange fact. The courier who brought news of the victory of Moncontour arrived at night, having ridden so hard that he had killed three horses. The Queen-mother was roused, and said, "I knew it." "In fact," says Brantôme, "she had the day before announced her son's success and some details of the fight." The astrologer attached to the House of Bourbon foretold that the youngest of the Princes in direct descent from Saint-Louis, the son of Antoine de Bourbon, would be King of France. This prophecy, noted by Sully, was fulfilled precisely as described by the horoscope, which made Henri IV. remark that by dint of lies these astrologers hit on the truth. Be this as it may, most of the clever men of the time believed in the far-reaching "science of the Magi," as it was called by the masters of astrology--or sorcery, as it was termed by the people--and they were justified by the verification of horoscopes. It was for Cosmo Ruggieri, her mathematician and astrologer--her wizard, if you will--that Catherine erected the pillar against the corn-market in Paris, the only remaining relic of the Hôtel de Soissons. Cosmo Ruggieri, like confessors, had a mysterious influence which satisfied him, as it does them. His secret ambition, too, was superior to that of vulgar minds. This man, depicted by romance-writers and playwrights as a mere juggler, held the rich abbey of Saint-Mahé in Lower Brittany, and had refused high ecclesiastical preferment; the money he derived in abundance from the superstitious mania of the time was sufficient for his private undertakings; and the Queen's hand, extended to protect his head, preserved every hair of it from harm. As to Catherine's devouring thirst for dominion, her desire to acquire power was so great that, in order to grasp it, she could ally herself with the Guises, the enemies of the throne; and to keep the reins of State in her own hands, she adopted every means, sacrificing her friends, and even her children. This woman could not live without the intrigues of rule, as a gambler cannot live without the excitement of play. Though she was an Italian and a daughter of the luxurious Medici, the Calvinists, though they calumniated her plentifully, never accused her of having a lover.
