In the late 1880s, a dashing young Italian aristocrat made an astonishing confession to the novelist Émile Zola. In a series of revealing letters, he frankly described his sexual experiences with other men—including his seduction as a teenager by one of his father’s friends and his first love affair, with a sergeant during his military service—as well as his “extraordinary” personality. Judging it too controversial, Zola gave it to a young doctor, who in 1896 published a censored version in a medical study on sexual inversion, as homosexuality was then known. When the Italian came across this book, he was shocked to discover how his life story had been distorted. In protest, he wrote a long, daring, and unapologetic letter to the doctor defending his right to love and to live as he wished. This book is the first complete, unexpurgated version in English of this remarkable queer autobiography. Its text is based on the recently discovered manuscript of the Italian’s letter to the doctor. It also features an introduction tracing the textual history of the documents, analytical essays, and additional materials that help place the work in its historical context. Offering a striking glimpse of gay life in Europe in the late nineteenth century, brings to light the powerful voice of a young man who forthrightly expressed his desires and eloquently affirmed his right to pleasure.
