I must tell you, charming ladies, that there are very many men who, because they have consumed a great part of their time over the study of letters, are persuaded that they are mighty wise, whereas in truth they know little or nothing. And while men of this sort think they are marking their foreheads with lines of wisdom, they too often only scoop out their own eyes,[28] which thing happened to a certain physician, greatly skilled in his calling, for he, while he deemed he was about to put a cheat upon another, was himself most ignominiously duped, to his own great injury, all of which you will learn from the fable which I will presently tell you. Gallese, King of Portugal, had a son whose name was Nerino, and in the bringing up of this boy he followed such a course that up to the time when he reached his eighteenth year Nerino had never once cast eyes upon a woman except his mother and the nurse who had the care of him. Wherefore when he had come to full age the king determined to send him to pursue his studies in the university of Padua, so that he might get a knowledge of Latin letters and of the tongue and manners of the Italians as well. And the plan which he had devised he duly carried out. When the young Nerino had come to Padua, he soon acquired the friendship of many of the scholars, and every day these would come to pay their respects to him, one of the above named being a certain Messer Raimondo Brunello, a physician. It chanced one day, as Nerino and this friend of his were conversing now about this thing and now about that, they engaged (as is the manner of sprightly youths) in a discourse anent the beauty of women, and on this subject the former took one view and the latter another. But Nerino, though he had never in times past cast eyes upon any woman save his mother and his nurse, declared with some heat that in his reckoning there could not be found in all the world any lady who should be more beautiful, more graceful, and more exquisite than was his own mother. And when, by way of putting this speech of his to the test, they brought divers ladies to his notice, he still declared that in comparison to his mother they were little better than carrion.
