But he had counted without the fact that the butterfly is the final development of its genus and cannot turn into anything else. It must be a butterfly to the end. Poor Marco soon found that his heart was as susceptible as ever, and could beat like a boy's on very slight provocation, but that unfortunately it was never his rich wife who provoked it to such unseemly and lively action. Yet her facial angle inspired him with a terror even greater than the attraction of a pretty face and a well-turned figure. She had a way of setting her thin lips over her prominent teeth which at the same time stretched the skin upon the bridge of her hooked nose while she looked at him from under her half-closed lids, that made his blood run cold, robbed the richest sauce of its delicious flavour, and turned the wine of Samos to vinegar in his glass. Daily, she grew older, sharper, more irritable; and daily, too, the heart of Marco Pesaro seemed to grow younger and the more to crave the companionship of a mate much younger still, or at least the near presence of those outward, visible, and tangible gifts of the gods, such as a deep warm eye, and a soft white hand, with which man has always associated the heart of woman. Zeno guessed all this and the rest too; the letter he had received needed no further explanation, and for old acquaintance's sake he had no objection to executing the commission Marco had thrust upon him. And now, all you who stop and gather round the story-teller in this world's great bazaar, to listen, if his tale please you, and to find fault with him if it does not, you cry out that if Carlo Zeno was really the hero history describes him to have been, he would have been very, very grieved at being asked to do anything so inhuman as to buy a pretty slave abroad to be sent home to a friend, even though the latter protested that the girl was to be trained as a companion for his wife. He would have been grieved and angry, he would have torn the letter to shreds, and would either not have answered it at all, or would have written to tell Pesaro that he was a brute, that men and women are all free and equal, and that to buy and sell them is high treason against the majesty of the rights of men.
