It must also be remembered, in qualification of the outrageousness, one might almost say the indecency, of his appeal to Andersen, that he had not in the remotest degree realized the extent of the stone-carver’s infatuation with the Italian. Neither physical passion, nor ideal passion, were things that entered into his view of the relations between the sexes. Desire with him was of a strange and complicated subtlety, generally diffused into a mild and brooding sentiment. He was abnormally faithful, but at the same time abnormally cold; and though, very often, jealousy bit him like a viper, it was a jealousy of the mind, not a jealousy of the senses. What in other people would have been gross and astounding cynicism, was in Mr. Quincunx a perfectly simple and even childlike recognition of elemental facts. He could sweep aside every conventional mask and plunge into the very earth-mould of reality, but he was quite unconscious of any shame, or any merit, in so doing. He simply envisaged facts, and stated the facts he envisaged, without the conventional unction of worldly discretion. This being so, it was in no ironic extravagance that he appealed to Andersen, but quite innocently, and without consciousness of anything unusual. Of the two men, some might have supposed, considering the circumstances, that it was Mr. Quincunx who was mad, and his interlocutor who was sane. On the other hand, it might be said that only a madman would have received the recluse’s appeal in the calm and serious manner in which Andersen received it. The abysmal cunning of those who have only one object in life, and are in sight of its attainment, actuated the unfortunate stone-carver in his attitude to his rival at this moment. “If some fairy or some god,” he said, “did lift the stone from her sepulchre and you from your sepulchre, my advice to you and to her would be to go away, to escape, to be free. You would be happy--you would both be happy! And the reason of your happiness would be that you would know the Devil had been conquered. And you would know that, because, by gathering all the stones in the world upon my own head, and being buried beneath them, I should have made a rampart higher than Leo’s Hill to protect you from the Evil One!” Andersen’s words were eager and hurried, and when he had finished speaking, he surveyed Mr. Quincunx with wild and feverish eyes. It was now borne in for the first time upon that worthy philosopher, that he was engaged in conversation with one whose wits were turned, and a great terror took possession of him. If the cunning of madmen is deep and subtle, it is sometimes surpassed by the cunning of those who are afraid of madmen.
