“In Christ’s name, Bannadonna,” impulsively broke in the chief, his attention for the first time attracted to the figure by his associate’s remark, “Una’s face looks just like that of Deborah, the prophetess, as painted by the Florentine, Del Fonca.” “Surely, Bannadonna,” lowly resumed the milder magistrate, “you meant the twelve should wear the same jocundly abandoned air. But see, the smile of Una seems but a fatal one. ’Tis different.” While his mild associate was speaking, the chief glanced, inquiringly, from him to the caster, as if anxious to mark how the discrepancy would be accounted for. As the chief stood, his advanced foot was on the scuttle’s curb. Bannadonna spoke:— “Eccellenza, now that, following your keener eye, I glance upon the face of Una, I do, indeed, perceive some little variance. But look all round the bell, and you will find no two faces entirely correspond. Because there is a law in art—But the cold wind is rising more; these lattices are but a poor defence. Suffer me, magnificoes, to conduct you at least partly on your way. Those in whose well-being there is a public stake should be heedfully attended.” “Touching the look of Una, you were saying, Bannadonna, that there was a certain law in art,” observed the chief, as the three now descended the stone shaft, “pray, tell me, then—” “Pardon—another time, Eccellenza; the tower is damp.” “Nay, I must rest, and hear it now. Here,—here is a wide landing, and through this leeward slit no wind, but ample light. Tell us of your law, and at large.” “Since, Eccellenza, you insist, know that there is a law in art, which bars the possibility of duplicates. Some years ago, you may remember, I graved a small seal for your republic, bearing, for its chief device, the head of your own ancestor, its illustrious founder. It becoming necessary, for the customs’ use, to have innumerable impressions for bales and boxes, I graved an entire plate, containing one hundred of the seals. Now, though, indeed, my object was to have those hundred heads identical, and though, I dare say, people think them so, yet, upon closely scanning an uncut impression from the plate, no two of those five-score faces, side by side, will be found alike. Gravity is the air of all; but diversified in all. In some, benevolent; in some, ambiguous; in two or three, to a close scrutiny, all but incipiently malign, the variation of less than a hair’s breadth in the linear shadings round the mouth sufficing to all this. Now, Eccellenza, transmute that general gravity into joyousness, and subject it to twelve of those variations I have described, and tell me, will you not have my hours here, and Una one of them? But I like—” “Hark! is that—a footfall above?”
