Bruno, who had not needed to be much with him in order to discover that this physician was but a dolt, had never such a jolly time in palming off his strange stories upon him, while the physician, on his part, was marvellously delighted with Bruno; to whom, having bidden him to breakfast, and thinking that for that reason he might talk familiarly with him, he expressed the amazement with which he regarded both him and Buffalmacco, for that, being but poor men, they lived so lightheartedly, and asked him to tell him how they managed. At which fresh proof of the doctor's simplicity and fatuity Bruno was inclined to laugh; but, bethinking him that 'twere best to answer him according to his folly, he said:--"Master, there are not many persons to whom I would disclose our manner of life, but, as you are my friend, and I know you will not let it go further, I do not mind telling you. The fact is that my comrade and I live not only as lightheartedly and jovially as you see, but much more so; and yet neither our art, nor any property that we possess, yields us enough to keep us in water: not that I would have you suppose that we go a thieving: no, 'tis that we go the course, and thereby without the least harm done to a soul we get all that we need, nay, all that we desire; and thus it is that we live so lightheartedly as you see." Which explanation the doctor believing none the less readily that he knew not what it meant, was lost in wonder, and forthwith burned with a most vehement desire to know what going the course might be, and was instant with Bruno to expound it, assuring him that he would never tell a soul. "Alas! Master," said Bruno, "what is this you ask of me? 'Tis a mighty great secret you would have me impart to you: 'twould be enough to undo me, to send me packing out of the world, nay, into the very jaws of Lucifer of San Gallo,(2) if it came to be known. But such is the respect in which I hold your quiditative pumpionship of Legnaia, and the trust I repose in you, that I am not able to deny you aught you ask of me; and so I will tell it you, on condition that you swear by the cross at Montesone that you will keep your promise, and never repeat it to a soul."
