Goodness, it's been over 30 years since I read "The Leopard". I tried to reread it about 15 years ago, but I had recently lost a Sicilian colleague, and the voice and mindset of the Prince were so much like my friend that I couldn't take it. (Not the morals, I hasten to add--my friend was a totally moral person.)
But one bit stuck with me for 30 years, so I want to share it. The arranged marriage turns out not to be happy, also childless, but the couple had a wonderful courtship:
"Those were the best days in the lives of Tancredi and Angelica.... But of that they were still unaware, in their pursuit of a future which they deemed more concrete than it turned out to be, made of nothing but smoke and wind. When they were old and uselessly wise, their thoughts would go back to those days with insistent regret........
Those days were a preparation for a marriage which, even erotically, was no success; a preparation, however, in a way sufficient to itself, exquisite and brief; like those overtures which outlive the forgotten operas they belong to and hint in delicate veiled gaiety at all the arias which later in the opera are to be developed undeftly, and fail."
