Claude, saddened and discouraged in his human affections, by all this, had flung himself eagerly into the arms of learning, that sister which, at least does not laugh in your face, and which always pays you, though in money that is sometimes a little hollow, for the attention which you have paid to her. Hence, he became more and more learned, and, at the same time, as a natural consequence, more and more rigid as a priest, more and more sad as a man. There are for each of us several parallelisms between our intelligence, our habits, and our character, which develop without a break, and break only in the great disturbances of life.
As Claude Frollo had passed through nearly the entire circle of human learning--positive, exterior, and permissible--since his youth, he was obliged, unless he came to a halt, ~ubi defuit orbis~, to proceed further and seek other aliments for the insatiable activity of his intelligence. The antique symbol of the serpent biting its tail is, above all, applicable to science. It would appear that Claude Frollo had experienced this. Many grave persons affirm that, after having exhausted the ~fas~ of human learning, he had dared to penetrate into the ~nefas~. He had, they said, tasted in succession all the apples of the tree of knowledge, and, whether from hunger or disgust, had ended by tasting the forbidden fruit. He had taken his place by turns, as the reader has seen, in the conferences of the theologians in Sorbonne,--in the assemblies of the doctors of art, after the manner of Saint-Hilaire,--in the disputes of the decretalists, after the manner of Saint-Martin,--in the congregations of physicians at the holy water font of Notre- Dame, ~ad cupam Nostroe-Dominoe~. All the dishes permitted and approved, which those four great kitchens called the four faculties could elaborate and serve to the understanding, he had devoured, and had been satiated with them before his hunger was appeased. Then he had penetrated further, lower, beneath all that finished, material, limited knowledge; he had, perhaps, risked his soul, and had seated himself in the cavern at that mysterious table of the alchemists, of the astrologers, of the hermetics, of which Averroès, Gillaume de Paris, and Nicolas Flamel hold the end in the Middle Ages; and which extends in the East, by the light of the seven- branched candlestick, to Solomon, Pythagoras, and Zoroaster.
That is, at least, what was supposed, whether rightly or not. It is certain that the archdeacon often visited the cemetery of the Saints-Innocents, where, it is true, his father and mother had been buried, with other victims of the plague of 1466; but that he appeared far less devout before the cross of their grave than before the strange figures with which the tomb of Nicolas Flamel and Claude Pernelle, erected just beside it, was loaded.
