Of late a great audacity of thought had come to Giovanni. He feared nothing, because he had nothing to lose. He had convinced himself that neither in the faith of Fra Benedetto, nor in the knowledge of Leonardo, would he find peace. Cassandra's prophecies gave him a glimpse of a new idea, so startling as to be terrible. Instead of turning away he approached it with the courage of despair. Day by day their souls came closer to each other.
Once he asked her why she hid what she believed to be the truth, why she even dissembled?
'All things are not for all men,' she answered. 'Martyrdoms, wonders, and signs are necessary for the crowd. Only those whose faith is imperfect die for their faith, that they may convince others, and themselves. But perfect faith is the same thing as perfect knowledge. Did the truths of geometry discovered by Pythagoras require that he should die in proof of them? Perfect faith is silent; and its secret is above profession, for the master said, "Ye know all, but be ye known of none."'
'What master?' asked Giovanni, thinking of Leonardo.
'Basil, the Egyptian Gnostic,' she replied; and explained that the great teachers of the early Christian ages, to whom faith and knowledge had been one, had called themselves Gnostics, or Knowers; and she went on to repeat to him many of their sayings, often strange and monstrous, like the visions of the delirious.
He was especially impressed by a legend as to the creation of the world and of man, put forth by the Alexandrine Ophites, or snake worshippers.
'"Above all the heavens is boundless Darkness, immovable, fairer than any light; the Unknown Father, the Abyss, the Silence. His only-begotten daughter, the Wisdom of God, separating from the Father, knew life, and sorrow, and darkened her splendour. The son of her travail was Jaldavaoth, the creating God. Falling away from his mother he plunged yet more deeply into existence, and created the world of the body, a distorted image of the spiritual world. In it was Man, formed to reflect the greatness of his creator, and to bear witness to his power. The elemental spirits, the ministers of Jaldavaoth, brought the senseless mass of flesh to Jaldavaoth to be endowed with life; but the Wisdom of God inspired it also with a breath of the divine wisdom, received by her from the Unknown Father. And then this mean creature, formed of earth and dust, became greater than Jaldavaoth its creator, and grew into the shape and the likeness not of him but of the true God, the Unknown Father. Four-footed Man raised his face from the earth, and Jaldavaoth, at the sight of the being which had slipped from his power, was filled with anger and alarm. He formed another creature, the Angel of Darkness, the serpent-like Satan, the wisdom accursed. And by the help of the serpent Jaldavaoth formed the three kingdoms of Nature; and set Man therein, and gave him a law. "Do this; do not that: if thou breakest the law, thou shalt die." For he hoped by the yoke of the law, and by the fear of death to recover his power over man. But the Wisdom of God still protected Man, and sent him a comforter, the Spirit of Knowledge—snake-like also, but winged like the morning star, the Angel of the Dawn, him to whom allusion is made in the saying, "Be ye wise as the serpent." And the Spirit of Knowledge went down to men and said, "Taste and know, and your eyes shall be opened, and ye shall be as gods."'
'Hearken, Giovanni,' concluded Cassandra; 'the men of the crowd, the children of this world, are the slaves of Jaldavaoth and of the serpent Satan, living under the fear of death, bound by the yoke of the law. But the children of light, those who know, the chosen of Sophia, the Wisdom of God, transcend all laws, overstep all bounds, are free as gods, are furnished with wings, remain pure in the midst of evil, even as gold glitters in the mire. And the Spirit of Knowledge, the Angel of the Dawn, leads them through life and death, through evil and through good, through all the curses and the terrors of the world of Jaldavaoth, to the great mother, Sophia, the Wisdom of God; and she bringeth them to the bosom of the great Darkness, which reigns above the heavens, which is immovable and fairer than any light; to the bosom of the Father of all things.'
And hearing this legend of the Ophites, Giovanni could not help inwardly comparing Jaldavaoth to the son of Kronos; the breath of Divine Wisdom to the fire of Prometheus; the Beneficent Serpent the Angel of the Dawn, Lucifer, Son of the Morning, to Prometheus the Titan. In all ages and nations, in the tragedies of Æschylus, in the legend of the Gnostics, in the history of Julian the Apostate, in the teaching of Pletho the philosopher, Giovanni found the echoes of the great discord, the same great struggle, which darkened his own spirit. Ten centuries ago men were suffering as he suffered now, were contending with the same double thoughts, were the victims of the same contradictions, the same temptations. The knowledge that this was so solaced him, yet it deepened his anguish. Sometimes he felt overwhelmed by all these thoughts as by drunkenness or delirium. And then it seemed to him that Cassandra only pretended to be strong and inspired and initiated into the mystery of truth, while in reality she was no less ignorant, no less astray than he was himself; and that the two of them were as helpless and lost as they had been twelve years before; and this new sabbath of half divine, half satanic lore was even more senseless than the Witches' Sabbath to which she had once invited him, and which she now despised as childishness. Giovanni became alarmed and wished to flee, but it was too late; curiosity drew him like a spell, and he felt he would not leave her till he knew all to the end; till he had found salvation and had perished with her.
Now about this time there came to Milan a famous inquisitor and doctor of theology, Fra Giorgio de Casale.
