"No sooner, therefore, had the Duke managed to inform her of his sentiments towards her, than she took credit to herself for so important a conquest. The attachment of a man approached by all the world with the titles of Your Grace and Your Highness tickled her pride, and filled her mind with the most absurd notions; so that she was indefinitely exalted in her own opinion, and thought the less of me. All that I had done for love of her, instead of exciting feelings of gratitude, now appeared but a contemptible offering to her charms, of which she no longer thought me worthy; and she seems not to have doubted that if the noble duke, who flattered her by his homage, had seen her before she had thrown herself away on me, he would have eagerly sought her hand. Infatuated by these absurd notions, and seduced by some well-timed presents which flattered her vanity, she yielded to the secret assiduities of his grace.
"Although they corresponded frequently, I had not for some time the slightest suspicion of their communications; but, at last, my eyes were unfortunately opened to my disgrace. One day I returned from hunting somewhat earlier than usual, and went directly to the apartment of my wife, who expected nothing less than to see me. She had just received a letter from her paramour, and was at the moment preparing a reply. She could not disguise her emotion at my unexpected coming; and as I perceived on the table paper and ink, I trembled,--for the truth rushed on my mind with the speed of all unwelcome conclusions. I commanded her to show me what she was writing, which she refused; so that I was compelled to use violence in order to satisfy my jealous curiosity, and drew from her bosom, in spite of her resistance, a letter which was to the following effect:--
"'Must I for ever languish in the despair of seeing thee again? Hast thou then cruelty enough to call sweet hopes into my heart, and let the short-lived blisses perish from delay? Don Juan leaves thee daily for the chase, or to repair to Toledo: would not Love then snatch these happy opportunities with eager joy? Think of the passion which consumes my life! Pity me, lady! and remember that if the happiness is great we hope to share, the greater is the torment which bars us its possession.'
