"And for myself, who have deeply studied the secrets of nature, seeing but now these clouds curling wantonly round the bosom of the hill, I was filled with mysterious longings at the sight, longings I know nothing of but that they spring from the region of my loins, and that, like the infant Hercules, they showed their strength from the very cradle. And these longings were not merely after rosy mists and floating clouds; they pictured very precisely a wench named Monna Libetta I made acquaintance with once in travelling, at Castro, at an inn where she was serving-maid and at the free disposal of the muleteers and soldiers frequenting it. "But the picture I framed in my mind of Monna Libetta, this morning, as I fared along the slopes of the hills, was wondrously embellished by the tenderness of recollection and the regrets of separation, and she was tricked out with all the pretty fancies that, springing from the loins as I said, presently send their fragrant fire coursing through all the body's soul, transfusing it with languishing ardours and pains that are a delicious pleasure. "For I would have you know, my Giovanni, that looking at her calmly and coldly, the girl was not greatly different from all the rest of the country wenches that, in the plains of Umbria and the Roman Marches, go afield to milk the cattle. She had dark eyes, slow and sullen, a sunburnt face, a big mouth, the bosom heavy, the belly tanned and the forepart of the legs, from the knee, shaggy with hair. Her laugh was ready and rude, in a general way; but in act with a lover, her face grew dark and transfigured as if with wonder at the presence of a god. 'Twas this had attached me to her, and I have many a time pondered since on the nature of this attachment, for I am learned and curious to search out the reasons of things. "And I discovered the force that drew me toward this girl Monna Libetta, maid-servant at the inn of Castro, was the same that governs the stars in heaven and that there is one force and one only in the world, which is Love. And it is likewise Hate, as is shown by the case of this same Monna Libetta, who was fiercely fondled, and just as fiercely beaten. "And I mind me how a groom in the Pope's stables, who was her chief lover, struck her so savagely one night in the hay-loft where he was bedding with her, that he left her lying there for dead. And he rushed crying through the streets that the vampires had strangled the girl. These be subjects a man must needs ponder if he would gain some notion of true physics and natural philosophy." Thus spoke the Subtle Doctor. And the holy man Giovanni sitting up on his bedding of dung, answered: "Nay! Doctor, is this language meet to address to a man that is to be hanged in a very short while? Hearing you, I am filled with doubt whether your words are the words of a good man and a great Theologian, or if they do not rather come from an evil dream sent by the Angel of Darkness."
