“She does not believe in miracles.”

“Does not believe in miracles? Then she does not believe in God either. So much the better! I have influence with the Archbishop of Milan. Tell her so. I can ruin her. I can destroy you all. It is true, Amalia. What books does she read? Doubtless some of them are on the Index. Let me see them. I will compile a list. A hint from me....”

“Not a word more, Casanova! Here she comes. Keep yourself well in hand; do not let your eyes betray you. Listen, Casanova; I have never known a purer-minded girl. Did she suspect what I have heard from you, she would feel herself soiled, and for the rest of your stay she would not so much as look at you. Talk to her; talk to her. You will soon ask her pardon and mine.”

Marcolina came up with the girls, who ran on into the house. She paused, as if out of courtesy to the guest, standing before him, while Amalia deliberately withdrew. Indeed, it actually seemed to Casanova that from those pale, half-parted lips, from the smooth brow crowned with light-brown hair now restored to order, there emanated an aroma of aloofness and purity. Rarely had he had this feeling with regard to any woman; nor had he had it in the case of Marcolina when they were within four walls. A devotional mood, a spirit of self-sacrifice knowing nothing of desire, seemed to take possession of his soul. Discreetly, in a respectful tone such as at that day was customary towards persons of rank, in a manner which she could not but regard as flattering, he enquired whether it was her purpose to resume her studies that evening. She answered that in the country her work was somewhat irregular. Nevertheless, even during free hours, mathematical problems upon which she had recently been pondering, would at times invade her mind unawares. This had just happened while she was lying on the greensward gazing up into the sky.

Casanova, emboldened by the friendliness of her demeanor, asked jestingly what was the nature of this lofty, urgent problem. She replied, in much the same tone, that it had nothing whatever to do with the Cabala, with which, so rumor ran, the Chevalier de Seingalt worked wonders. He would therefore not know what to make of her problem.

Casanova was piqued that she should speak of the Cabala with such unconcealed contempt. In his rare hours of heart-searching he was well aware that the mystical system of numbers which passed by that name had neither sense nor purpose. He knew it had no correspondence with any natural reality; that it was no more than an instrument whereby cheats and jesters—Casanova assumed these roles by turn, and was a master player in both capacities—could lead credulous fools by the nose. Nevertheless, in defiance of his own better judgment, he now undertook to defend the Cabala as a serious and perfectly valid science. He spoke of the divine nature of the number seven, to which there are so many references in Holy Writ; of the deep prophetic significance of pyramids of figures, for the construction of which he had himself invented a new system; and of the frequent fulfilment of the forecasts he had based upon this system. In Amsterdam, a few years ago, through the use of arithmancy, he had induced Hope the banker to take over the insurance of a ship which was already reported lost, whereby the banker had made two hundred thousand gold guilders. He held forth so eloquently in defence of his preposterous theories that, as often happened, he began to believe all the nonsense he was talking. At length he went so far as to maintain that the Cabala was not so much a branch of mathematics as the metaphysical perfectionment of mathematics.

At this point, Marcolina, who had been listening attentively and with apparent seriousness, suddenly assumed a half-commiserating, half-mischievous expression, and said:

“You are trying, Signor Casanova”—she seemed deliberately to avoid addressing him as Chevalier—“to give me an elaborate proof of your renowned talent as entertainer, and I am extremely grateful to you. But of course you know as well as I do that the Cabala has not merely nothing to do with mathematics, but is in conflict with the very essence of mathematics. The Cabala bears to mathematics the same sort of relationship that the confused or fallacious chatter of the Sophists bore to the serene, lofty doctrines of Plato and of Aristotle.”

“Nevertheless, beautiful and learned Marcolina, you will admit,” answered Casanova promptly, “that even the Sophists were far from being such contemptible, foolish apprentices as your harsh criticism would imply. Let me give you a contemporary example. M. Voltaire’s whole technique of thought and writing entitles us to describe him as an Arch-Sophist. Yet no one will refuse the due meed of honor to his extraordinary talent. I would not myself refuse it, though I am at this moment engaged in composing a polemic against him. Let me add that I am not allowing myself to be influenced in his favor by recollection of the extreme civility he was good enough to show me when I visited him at Ferney ten years ago.”

“It is really most considerate of you to be so lenient in your criticism of the greatest mind of the century!” Marcolina smilingly retorted.
