Spain had not in the sixteenth century ceased to be celebrated for its magicians, who still retained a modicum of the occult philosophy of the Moorish doctors of Toledo and Granada. Perhaps the most celebrated of these comparatively modern masters of magic was Doctor Eugenio Torralva, physician to the family of the Admiral of Castile. Educated at Rome, he early became a pronounced sceptic, and formed an intimacy with a certain Master Alfonso, a man who, after changing his Jewish faith for Islam, and that again for Christianity, had at last become a free-thinker. Another evil companion was a Dominican monk called Brother Pietro, who told Torralva that he had in his service a good angel called Zequiel, who had no equal in the spiritual world as a seer, and was besides of such a disinterested temperament that he served only those who had complete confidence in him and deserved his attachment. All this excited Torralva's curiosity to an unbounded degree. He was one of those people, fortunate or otherwise, in whom the love of mystery has been deeply implanted, and when Pietro generously proposed to resign his familiar spirit to his friend's keeping he eagerly accepted the offer. Nor did Zequiel himself offer any opposition to this change of master, and, appearing at the summons of Pietro, assured Torralva that he would follow his service as long as he lived, and wherever he was obliged to go. There was nothing very startling in the appearance of the spirit, who was dressed in a flesh-coloured habit and black cloak, and had the appearance of a young man with an abundance of fair hair. From this time onward Zequiel appeared to Torralva at every change of the moon, and as often as the physician required his services, which was generally for the purpose of transporting him in a short space of time to distant places. Sometimes the spirit assumed the appearance of a hermit, at others that of a traveller, and even accompanied his master to church, from which circumstance Torralva concluded that he was a beneficent and Christian-minded spirit. But, alas! Dr Torralva was to find, like many another, that attendance at the sacred edifice is not necessarily a guarantee of piety.
