Nearly 200 years ago, the French novelist Honoré de Balzac created a remarkable character, Vautrin, a charming, hyper-masculine master criminal, and a man who loves men. In three of Balzac’s most popular novels an important part of the plot turns on Vautrin’s love for an exceptionally handsome, much younger man: 21-year-old Eugène de Rastignac in Père Goriot, twenty-year-old Lucien de Rubempré in the climactic scene of Lost Illusions and in A Harlot High and Low (Splendeurs et misères) and 27-year-old Théodore Calvi (nicknamed “Madeleine”), who doesn’t appear until the end of the last book, when Vautrin is around fifty, but who had also been involved with Vautrin a decade before, at the age of eighteen.
p 611 | The "man of taste" was Oscar Wilde, who in his essay "The Decay of Lying" wrote, "One of the greatest tragedies of my life is the death of Lucien de Rubempré in Splendeurs et misères."
